Use your data

Format

Topics are followed by software demonstrations and reviews.

Today we'll discuss ESRI MapIt products. After a brief introduction, we'll focus on how to

prepare, serve, and use your data using product features included with MapIt.

Each section will be followed by a demonstration.





What isESRI MapIt?

So what is ESRI MapIt?





Product overview

New mapping product

Helps prepare your data for use in mapping applications

ESRI MapIt is a new software and services solution which allows your organization to quickly

create highly interactive maps in your Microsoft SQL Server and Excel data, which can beshared virtually anywhere through SharePoint portals, Silverlight Web-based applications, and

desktop applications.

Technically, it's designed as a lightweight Web mapping solution to prepare, serve, and use

spatially enabled data stored in SQL Server 2008.

Much of your data may have a geographic component that defines a location and allows it to bedisplayed in the map. MapIt provides the tools you need to make this possible.





Product overview

New mapping product


REST-ful services for rich, interactive client applications

Natively supports both 32- and 64-bit Windows

MapIt includes a REST-ful interface for consuming spatially enabled data and SQL Server.

A set of clients is packaged with the product, a Silverlight WPF API for building rich, interactive

Web and desktop client applications, and an out-of-the-box mapping Web Part for SharePoint

sites. All MapIt features are supported in pure 64- and 32-bit environments.





Product overview

New mapping product


REST-ful services for rich, interactive client applications

Natively supports both 32- and 64-bit Windows

Takes advantage of existing investments

Microsoft IIS

SharePoint

Office

SQL Server 2008

Silverlight/WPF

MapIt enables you to take advantage of existing infrastructure to manage, serve, and use

geographic data. No modifications or schemas or data types with SQL Server are required.Instead, native capabilities for using geographic data and SQL Server are leveraged. Likewise,

serving data on your SQL Server instance is enabled via an ArcIMS Web service that connects to

your instance using standard methods.

You can then use your data for interactive mapping applications that you can build using a

Microsoft Silverlight or Windows Presentation Foundation, or WPF, and host within SharePoint.





What MapIt does for you

Spatially visualizes data

Point and area data

Shows patterns and relationships

So what does MapIt do for you? Basically, MapIt allows your users to easily explore the

geographic components of your organization's data. Your map's data can create a powerful visualtool for decision making, exposing trends that might otherwise remain hidden.





What MapIt does for you

Spatially visualizes data

Point and area data

Shows patterns and relationships

Integrates with the Cloud

Data and services

• Bing and ArcGIS Online

• Demographics and business data

MapIt supports integration with public services and deployment for public use. This means use

with Internet services and data, affectionately termed the cloud. This includes the Microsoft du jour services platform. In general, data, services, and applications created and hosted using

MapIt features can be incorporated with other business data and services to devise effective

solutions and presents intuitive and aesthetic results.





Workflow overview

Prepare

Spatial Data Assistant

• Assists loading “geo” data into SQL Server 2008

• Spatially enables existing SQL tables

In general, MapIt supports a prepare, serve, and use workflow. Prepare involves creating,

managing, or manipulating data in SQL Server. MapIt includes a stand-alone WPF application, aSpatial Data Assistant, which enables you to load geoenabled data into SQL server, or spatially

enable existing SQL tables.





Workflow overview

Prepare




Serve

Spatial Data Service

• Web service for SQL Server Spatial

Serve involves exposing your SQL Server data via standard Web service protocol. MapIt

includes the Spatial Data Service as a REST-ful Web service. This means a client can use thelightweight REST format over HTTP to communicate with the Spatial Data Service and query

geographic data tables in SQL Server.

ESRI Map Web part to add mapping to SharePoint

Silverlight\WPF API to build rich Web and desktop clientapplications

Use involves creating an application to consume tables within SQL Server using the Spatial Data

Service. Two premier clients are included with MapIt. The ArcGIS API for Microsoft Silverlightand WPF is a lightweight mapping API for developers to create rich Web, Silverlight, or desktop

WPF clients.

The ESRI Map Web Part for Microsoft SharePoint is an in-the-box, deployable SharePoint Web

Part that contains a map built on the Silverlight platform. The map is configured in SharePoint at

runtime via a user interface that allows you to choose a basemap, add operational layers,

SharePoint lists, MapIt services, or ArcGIS Server map services. It also allows you to useoperational layer properties and define those properties such as name, transparency, field aliases,

and symbology.





Softwaredemonstration

Let's move on to the software demonstration portion.

Let's step to the install to see what features are included with the product, and how they're

initially configured. First, you'll download the 32-bit or 64-bit version of the product, depending

on the platform you're installing on.

Note we also offer a trial version for you to test the functionality of the product before purchase.

If you haven't already, visit www.esri.com/mapit for more information.

In this case, I'm installing on Windows Server 2003, 32-bit. I'll start the 32-bit setup, and stepthrough the dialogs.

We'll accept the license agreement and go to the next page which lists the features in MapIt.We’ll see Spatial Data Assistant, Spatial Data Service, Web client API, which is the

Silverlight/WPF API, and the ESRI Map Web Part for SharePoint.

Now we actually need to configure the Spatial Data Service. First, I need to choose an IS server

in which I want to install the ASP .NET service. I have a number of servers available, one of

which I created explicitly to support the Spatial Data Service. I call it IS Server for MapIt; it's

hosted on port 82. Note here I also have a couple of SharePoint servers which we'll use later inthe session.




In this case I need to define the name of the virtual director for the service. The default is theacronym SDS, short for Spatial Data Service, but I can choose whatever I'd like to. I'm going to

accept the defaults and go to the next dialog.

In this dialog I need to define the server and the SQL Server instance of the service that I'll

connect to. It's on a different machine. I'm going to type in the name here and the instance name.I'm using SQL Express 2008.

I also must enter user credentials, either Windows or SQL Server. The service will use these

credentials to connect to SQL Server, so these credentials will be encrypted within the Web

config of the ASP .NET service.

Note, the set up will check the validity of the SQL Server instance. If a SQL account is specified,

it will attempt to connect. If a Windows account is specified, it will only check to make sure it's avalid Windows account; it will not connect.

In this case, I'll specify a SQL Server account that I've created. I need to have at least selectedprivileges on tables within a specific schema or database reader privileges for this specific

account within SQL Server to be able to query tabular data.

We'll proceed with the install. You'll note that it's relatively quick. Lay down our components,each of the features. When we're finished, we should be prompted with a license configuration

utility. So the license configuration utility shows us a couple of options. We can use the

evaluation version by default, or we can use the licensed version.

Note that the evaluation version is limited to 60-day trial. So the first time you use the SpatialData Assistant, or the Spatial Data Service, it will time out after 60 days. The spatial data system

is limited to geocoding 100 records, or loading 100 records from a shapefile. The Spatial Data

Service is limited to returning 100 records from query.

In this case we're going to use the licensed version, and assuming we purchased a license, I can

navigate out to a location that I had my license, reference it from the dialog and get a notificationthat my license configuration has succeeded.

Note also that we have a set of program menu items that have been added. We're going to step

through for the remainder of this session, each of these program items, and see how each is usedwithin the MapIt workflow.





Review

The MapIt product includes the following features



ArcGIS API for Microsoft Silverlight/WPF

ESRI Map Web Part for Microsoft SharePoint

So to review, installation of MapIt includes four components. The Spatial Data Assistant, the

Spatial Data Service, the ArcGIS API for Microsoft Silverlight APF, and the ESRI Map Web Partfor Microsoft SharePoint. We'll cover each of these in more detail in the sections to come.





Prepare your data

After installation, the first step in the workflow involves preparing your data.






Helps prepare data for use with mapping applications

Assign locations to SQL Server data using address fields

Load standard ESRI shapefiles into SQL Server

• Open format commonly used for sharing geographic data

Load standard geographies from an ESRI Web site

• Available for free from a standard data catalog

The Spatial Data Assistant is a stand-alone WPF application that assists you in preparing your

data for use in a mapping application. It assists you in three ways. One, it assigns locations orgeography, in tables and SQL Server that contain address information. Two, it enables you to

load your own spatial data stored in a shapefile format into SQL Server. Note that the shapefile is

a common standard used to share geographic data. And three, ESRI provides a set of freegeographic datasets you can load directly into SQL server.






So, let's see the Spatial Data Assistant in action. So let's get started with the Spatial Data

Assistant. I'm going to show a Windows Server 2003 machine, 32-bit. I'm going to navigate tothe program menu item for Spatial Data Assistant, which we've just installed. And in this dialog,

I'll be able to specify the server name and the instance that I want to connect to. Then I can

define Windows or SQL Server authentication. In this case I'm going to use my Windowsaccount, which has write privileges to the database.

Two dialogs are provided, one to create points from addresses, and another to load spatial data.

What I'd like to do is create points from addresses. On SLQ Server I have a database with a tablethat contains addresses without geography. There's no spatial component in this table. This is on

my SQL Server machine, the machine where I have my SQL Server instance running using SQL

Server Management Studio to view this table. You can see in my databases I have a demodatabase, and I have a table named LmbrStores.

In LmbrStores, I have some address information that I'd like to geocode. Addresses including theaddress field, ZIP, city, and state. What I'd like to do is assign a geometry column to this, and use

the address to generate a location, known as geocoding.

So let's click on the Create points from address and I'll specify the database—demo—and thetable that contains my address information, LmbrStores. But I can also show advanced options

here. It gives me the ability to assign a spatial reference to align my data geographically. I can

define either a Bing Maps spatial reference, which is in the Mercator projection. I can useArcGIS Online, which uses a geographic. I can also define a well-known ID of a spatial




reference if I so choose. In this case I'm going to use the ArcGIS Online data, or geographicspatial reference.

I can also choose the service that I want to use to generate my locations for my address attributeinformation. Bing Maps provides a geocode service that enables me to use either the production-

level services or staging services. Now Bing Maps requires a developer account to access both. If we want access to production services, you need to purchase a license. If you haven't purchased alicense, you can use their staging environment.

ArcGIS Online provides a set of services that enables you to find locations or geocode to North

America or European addresses. In this case, my addresses happen to be in North America, so I'llselect that option. Let’s go on to the next dialog. In this dialog, depending on which service I've

chosen, I need to match the fields in my table to this address inputs to the service. Note that some

fields are already matched based on naming assumptions. I'll specify the state, since that wasn'tdefined, the state province which happens to be a field in my SQL Server table, and I'll click on

Create points.

Note that once the process is initiated, the application will provide feedback as to the progress of

the operation.

Note that the desktop application is communicating with the remote service, passing attributeinformation to determine a geocode location. When geocoding, there are often different scores,

or match scores or reliability ratings, based upon the match between the attribute information and

the base layer or reference data that the service provides.

When the geocode process is finished, we'll get a brief summary to show the results of theprocess and what to expect when we view our data.

When completed, we'll go back to the machine that has my SQL Server instance on it and take alook at the table and see how it's changed.

Okay, out of 332 records, they were all located successfully. It looks like there were multiplematches for a couple, for most of those, and we selected the first match, or the best match when

generating a location.

Let's go back to the SQL instance. We should see our spatial results. There they are in the shapecolumn. There's also in SQL Server Management Studio one of the spatial types capabilities

within SQL Server 2008. We can also get spatial results, so we can see the spatial component

within Management Studio, and get an idea using this Cartesian coordinate system, where thosepoints show up on a grid.

Great. So it looks like our address information was geocoded successfully.

Let's move on to the other option, loading existing spatial data into SQL Server. I'll click on Load

spatial data, and this enables you to select between either a catalog of standard datasets, which




are hosted by ESRI, or you can load your own shapefile into SQL Server. In this session we'regoing to select a standard dataset.

We'll navigate to something reasonably lightweight, in this case the U.S. states. Note here wehave both United States and world data available. I'll click Next to define which database I want

to load this into. I'll specify U.S. states. I'm going to load this as geographic, so I'll specify thegeographic name. In my advanced options, I can define the spatial reference I want to use toassign this spatial data when it's loaded into its SQL Server instance, and I can click Load data.

The application will go out to the standard geography, download that geography, and load it

within my SQL Server instance.

Note also the help system that comes with MapIt. This provides you with a variety of

information in detail associated with using the Spatial Data Assistant. So if you need additional

information on working with the Spatial Data Assistant, this is a great place to start.





Review

Spatial Data Assistant helps you

Add data to SQL Server

Spatially enable data in SQL Server

So to review, the Spatial Data Assistant gives you the ability to add geographic data to SQL

Server, and spatially enable the data with the locational components, such as addresses, alreadyin SQL Server. Note we're merely working with the spatial types inherent to SQL Server 2008.

The Spatial Data Assistant makes it easier to generate or modify data using these spatial types,

but you can use other utilities, functions, and tools to generate spatial data in SQL Server as well.





Serve your data

A pivotal step in exposing spatial data hosted in SQL Server is providing a common standard

format by which clients can query and consume data.






ASP.NET REST-ful Service

Supports spatial and attribute queries

This is provided in MapIt via the Spatial Data Service, an ASP. NET Web service that uses the

lightweight REST format for client interaction. The service supports querying tables in a SQLServer instance, using either spatial or attribute filter.








Connects to SQL Server 2008 using standard methods

It connects to SQL server using standard methods and protocols. Some of these properties are

visible, and can be managed within the Web services Web .config file. For instance, a Windowsor SQL account is provided during installation and is used to connect to a named SQL Server

instance.

This information is encrypted in the Web .config. Note the account defined must have at least

select permissions on a schema or table, or read permissions on the database in which you want

to query content.









Spatial Data Services Directory application

• Simple browser-based application

• Browse databases, tables, and views

• Perform query operations

• Copy and paste URLs into clients

The Spatial Data Service also provides a visual user interface in a browser to traverse and

discover databases and tables, table metadata such as fields and primary keys, and allows you toinitiate spatial attribute queries to return data.

The URLs discovered using the services directory can be used by clients to consume spatial dataexposed by the Spatial Data Service.









Spatial Data Services Directory application

• Simple browser-based application

• Browse databases, tables, and views

• Perform query operations

• Copy and paste URLs into clients

Support Projection on the Fly

Any standard WKID (from/to)

As part of the query operation on tables, the Spatial Data Service also supports changing the

spatial reference on the fly. This means you can define a well-known ID, or WKID, for a spatialreference of your choice to align the results of the query to other layers in your client application.






So let's move on to the software demonstration for the Spatial Data Service. I'll go back to my

machine where I have installed MapIt, and I'm going to navigate to the Spatial Data Serviceprogram menu item.

A browser window will pop up and display the home page for the Spatial Data Servicesdirectory. The services directory is a set of databases available in the SQL Server instance that

we're connecting to. Those databases we can click on and we can traverse the tables that they

contain, in this case we're interested in the LmbrStores table that we recently geocoded addresses

in and added a spatial column to. We can discover field metadata by clicking on the table,whether or not we have a primary key, the name of the field, and the fields that are contained

within the table.

Note there's a shape column of a specific SQL Server type, and it also contains the spatial

reference ID, or the well-known ID, for this service geometry type.

There's one supported operation, query. Query is what will be used by clients to interact with

spatial data within SQL Server. On this page we can construct queries and see what results will

return. In the Where clause, if I add a 1=1, this will return all features within the table. We scroll

down to the bottom. What we'll see here is a comprehensive list essentially of results that werereturned. We're just going to, by default, display the top 50 of those results.

What we can see here is that the geometry is returned, in this case point geometry, with itscoordinates and the spatial reference. I know we can project on the fly using Spatial Data




Service, so you can enter another well-known ID, in this case, a well-known ID for Bing Maps ora Web Mercator projection. We'll initiate another query, and we'll see that the spatial component

has changed. Note the data in the table in SQL Server instance has not changed. Merely the

geometry as stored has been projected on-the-fly by the Spatial Data Service before beingreturned to the client.

We can also, in the returned fields, be able to find all fields using an asterisk. This will give us alook at all fields as returned for each row within our table.

We can also choose between HTML and JSON. HTML is really just designed for the services

directory so that you can view the data more aesthetically. JSON is used for programmaticclients. We can see that content here.

Note one thing that's very important about the services directory is the ability to retrieve the URLthat a client will use to query our data, spatial data within SQL Server.

This URL will come in handy in future sessions when we cover working with the Silverlight APIas well as the ESRI Map Web Part.

Note, by default, the Spatial Data Service is limited to returning a thousand records at a time.

The Spatial Data Service admin can change this in the Web .config, or note that a client will berequired to iterate from multiple queries to return more than a thousand records. Note there's also

a help system included with the services directory.

In this case, each page within the service directory has its own help content, and we can scroll

down, we can see the different parameters that are provided via the REST for request, to a tablewithin our SQL Server instance using the Spatial Data Service.

One other item to note is that the Spatial Data Service leverages caching for improvedperformance. If you've recently upgraded or changed content of a database or a tables within

SQL Server, you will likely need to refresh the Spatial Data Service cache. Note the convenient

Refresh link which you click on in the services directory to refresh your content.

Note in the next two sessions, we're going to cover using the Spatial Data Service and client

applications and the services directory to consume and display spatial data stored in SQL Server.





Review

Spatial Data Services enable you to

View your SQL Server instance content

Use REST to query tables in a SQL Server instance

So to review the Spatial Data Service, it provides a gateway to spatial data, stored in SQL Server

by, one, providing a services directory to traverse SQL server instance content and discoverURLs; and two, providing a lightweight REST API to query tables and return results.

You can modify the behavior of the Spatial Data Service such as record limits to cache mode inits Web .config. See the MapIt help for a complete list.

You can also deploy multiple Spatial Data Service instances. Merely copy and paste the REST

folder, included with the MapIt install, to a location of your choice, and then use the SDS configutility included with the product, on the command line, to set up the IIS Web application.





Use your data

Once your geographic data is prepared and loaded into SQL Server and served using the Spatial

Data Service, you can construct a client to consume and display your spatial data on a map. Twoclient features are included with MapIt: the ArcGIS API for Microsoft Silverlight/WPF, and the

ESRI Map Web Part for Microsoft SharePoint.

First, we'll take a closer look at the ArcGIS API and build a Silverlight application.





ArcGIS API for Microsoft Silverlight\WPF

Designed for the Silverlight and WPF Platform

Create rich, interactive Web and desktop applications

Integrate ArcGIS Server, MapIt, and Bing Maps

The ArcGIS API for Microsoft Silverlight/WPF is designed for developers to create applications

built on the Microsoft Silverlight or WPF platforms, both of which are integrated with VisualStudio 2008 and Visual Web Developer Express 2008. The API enables developers to create rich

Internet and desktop applications that utilize the powerful mapping, geocoding, and

geoprocessing capabilities provided by ArcGIS Server and Bing Map services.

To use the API, simply reference the ArcGIS API for Microsoft Silverlight or WPF libraries

included with MapIt, and start creating your Silverlight or WPF application using Visual Studio

or Visual Web Developer.









Libraries

ESRI.ArcGIS.Client.dll – Core library (map, layers, graphics...)

ESRI.ArcGIS.Client.Bing.dll – Support for Bing Maps services

ESRI.ArcGIS.Client.Toolkit.dll – Controls for working with themap

The API is composed of three libraries. A core library, which contains the map control, layer

support, graphics, geometry, and symbolization. The Bing library provides support for Bing Mapservices, such as map imagery, geocoding, and routing. And the toolkit, which provides a set of

common controls to enhance the core components in your application, such the navigator, the

magnifying glass, or a toolbar.









Libraries

ESRI.ArcGIS.Client.dll – Core library (map, layers, graphics...)

ESRI.ArcGIS.Client.Bing.dll – Support for Bing Maps services

ESRI.ArcGIS.Client.Toolkit.dll – Controls for working with themap

Requirements

Visual Studio 2008 sp1

• Express to Team Suite

• Microsoft .NET Framework 3.5 sp1

Silverlight tools for Visual Studio (add-on)

To get started with using the ArcGIS API for Microsoft Silverlight/WPF, you'll need to install

Visual Studio 2008 Service Pak 1, or Visual Web Developer 2008 Service Pak 1. Note bothinclude the .NET Framework 3.5, but you'll need to install Service Pak 1 for the 3.5 framework,

as well.

You'll also need the Silverlight tools add-on for Visual Studio. More information on the

Silverlight requirements is available at the Silverlight .NET Web site.






On to the software demonstration. In this example, we use Visual Studio 2008. To create a new

Silverlight application in Visual Studio, go to File > New project and select the Silverlight nodeunder the language of your choice, C # or VB .NET.

Then select the Silverlight application template. When you're prompted to create a page thathosts your Silverlight application, note that by default, browser security restrictions do not allow

access to remote services when a file is loaded from the file system. Remote services include

ArcGIS Server, Bing, and MapIt services, some of which will be used in this application.

With this in mind, the page that contains the Silverlight application needs to be hosted and

accessed via a Web server. Fortunately, Visual Studio includes an ASP .NET development server,

which can be used. In this example, make sure the option to add a new ASP .NET Web project tothe solution to host Silverlight remains selected.

At this point, your Silverlight application and the Web host application will be created. Bydefault, the Silverlight application includes a page .xaml, or XAML file, as a container for

Silverlight controls.

We'll only add markup to the XAML page in this demonstration.

In Visual Studio, add our reference to the core library, ESRI.arcgis.client.dll.




The library is located in the installation directory for MapIt under the client API folder. Notethere is both the Silverlight and the WPF folder containing ArcGIS API assemblies compiled for

either the Silverlight or WPF platform. In this case we're building a Silverlight application, so

make sure you reference the assemblies within the Silverlight folder.

Note that no controls will be available in the Visual Studio toolbox; instead I've added a set of pre-created XAML markup shortcuts that I'll use to create the application for this demonstration.

First I'd like to add a set of references that I'll use while building the application. I want to

remove the height and width so the Silverlight application will fill the browser window, then I'm

going to add a set of references. These references most of which actually go to the assembly thatI just added, ESRI.arcgis.client.

This enables me now to use ArcGIS API Silverlight content with any application.

Now, it's in the grid control that provides a layout. I'm going add a new map. I've given a unique

name, and I've provided an extent. This is a geographic extent that includes the continentalUnited States. There is also a layers collection defined here, and it contains a single base layer,

an ArcGIS Online tiled map service, street map service, that contains precached tiles of roads,

landmarks, and relief data. We're going to use this base layer to provide context and really an

aesthetic backdrop for our data from MapIt.

To use MapIt data, we need to access tables that the MapIt Spatial Data Service provides access

to. Namely these tables contain geometry and attributes.

A query from the client, in this case the Silverlight API which uses the Spatial Data Service, willreturn features, which can be rendered in the map. So in this case, I'm going use a convenient

layer type provided by the Silverlight API named, FeatureLayer.

A feature layer, component merely requires a URL from which to retrieve features. We can use

the Spatial Data Service services directory to get the URL we need. In this case we're interested

the LmbrStores locations we geocoded with the spatial data systems.

Let's navigate out to the services directory, now to get to the table of interest, in this case,

LmbrStores. You can copy and paste the URL directly from the browser into the URL properties

for the feature layer, that you'd like to access.

The feature layer itself includes a default renderer, so we don't need to specify one to see our

MapIt table content. Let's see what it looks like.

As the application starts, we'll see our basemap, our street map layer from ArcGIS Online, and

the geocoded locations shown on top of the street map layer. Here we can see the locations, butwe need to enhance the look and feel of these locations to provide more information to the user.

In Silverlight, frequently a collection of resources is defined in XAML to be used by other visualelements on the page to define the visual content. In this case, I need to add some symbology and




renderer resources that I can use for the remainder of the demonstration to change the look andfeel for the rendering of the points that we're retrieving from MapIt.

What I've added here is a single simple marker symbol that I can use to render points. I've got agroup of marker symbols used to render points, all bundled within a class breaks renderer. The

class breaks renderer allows me to find minimum/maximum values within which I want to use adefined symbol type. I've also defined the attribute on which I want to retrieve these values that Ican apply these symbols. There's also a dictionary converter included here that will be used in a

data binding scenario later in this exercise.

What's important here is I want to be able to enhance the rendering of the data retrieved from myMapIt table for LmbrStores. So there's a renderer attribute on the feature layer by which I can

reference a resource, in this case, a renderer resource. I'm interested in the class breaks renderer

that I defined in the minimum/maximum values for my sales field.

I'm going to reference this as a static resource, a resource that doesn't change at runtime. And I'm

also going to add a set of output fields of interest to my feature layer.

And the field that'll be used here is SALES, and the feature I’m going to be using,

COMPANYNAME, for demonstration later. Let's see how this looks. Okay. So we can see that

the class breaks renderer and the different symbols for different values of scales are applied. Aswe zoom in, you can see that the points themselves start to separate a bit and we can see the

difference between individual locations. Unfortunately, we don't get any attribute information,

and at some scales, some of the points overlap one another, so it's difficult to tell just how manylocations happen to be in a specific region.

We can solve this with a cluster renderer, which is included with the ArcGIS Silverlight API.

Let's define a cluster renderer. First I'm going to remove my class breaks renderer, and I've

created a cluster renderer. I'm going to add that to the page and note here, the feature layer itself contains a clusterer property. The cluster itself can contain a flare cluster instance, which has a

set of properties that we can define. But in general, the clustering itself actually identifies groups

of points in a layer that are within a given cluster distance, or radius, in this case.

The cluster distanced is dependent on scale at which the map is displayed. So as you zoom in,

fewer points are clustered, and as you zoom out, more points are clustered. Clusters can be

rendered in two ways, as a flare symbol and as a cluster symbol. With the cluster you can definehow many points within a given radius in pixels will be clustered using a flare symbol. The flare

symbol is merely an animated symbol that we'll see in a moment. In this case, the maximum flare

count is 10. So anywhere between 10 and the maximum flare count will use a flare symbol.Anything greater than the maximum flare count will use a cluster symbol. Single features will be

rendered using the feature symbol attribute on a feature layer.

The single feature symbol I've defined in my resources, and I've given it a name, MyRedMarker

symbol. I'll define that there. Let's go ahead and run it and see what it looks like. Okay. The

geocoded locations now are clustered, based upon the definitions provided within our featureclusterer. Note as we hover over these cluster locations, which indicate the number of points




within a specific defined radius, we have a flare symbol. And you can see the animation of theflare symbol as we hover over those points to show us the individual points themselves.

Note here individual features are rendered using the simple symbol red marker symbol that wedefined and the cluster symbol doesn't have any animated or interactivity at this point. If we

zoom in, we change the map scale. We can see that clustering is recalculated based upon thecurrent map scale and the radius is reapplied.

And to enhance this application further, what would be nice is being able to provide maybe a

pop-up, or additional information on individual points to give us attributes, or attribute

information. These pop-ups that we're going to construct are called MapTips.

So, within the feature layer, there's a MapTips property. I'm going to add a block of text here

which contains a predefined MapTip. Now MapTips are merely containers for other Silverlightuser interface containers, or other user interface elements. In this case, we have a grid with a set

of StackPanels. Add some text blocks to display field values for features. Now data binding is

used to associate a feature set as a source and the text blocks as a target within the bindingscenario.

To define as a property for our text, we're going to be binding to the data context, within the

scope, which is the data context that applies to the feature layer. We're using my dictionaryconverter to convert between the feature set, which is a dictionary, and we're using a converter

parameter which in this case happens to be a field name within that dictionary that is our feature

set.

We're defining company name, city, and sales, all of these will show up within the container thatwe define for a MapTip upon hover of the feature at runtime.

Let's see how this looks. Now when we hover over a feature, we can see individual pop-ups orMapTips display with attribute information associated with that point. As we zoom in, clusters

are recalculated, and we still have the pop-up values.

ArcGIS API for Microsoft Silverlight/WPF

Lightweight yet powerful client API

Add MapIt tables as operational layers

Graphics or feature layers

Define rendering, symbology, clustering, Map Tips

So we’ve completed building our Silverlight application and showed how to integrate geographic

data, prepared and served using MapIt components. As we've seen, the Silverlight/WPF API istruly a lightweight yet powerful service client. Spatial data accessed by the MapIt Spatial Data

Service can be consumed and rendered as graphic features in a map.

The feature layer provides a convenient means by which we can reference the URL that contains,

or that queries, spatial data within SQL Server using the Spatial Data Service. Enhanced feature

functionality, contained by the Silverlight WPF/API, allows us to apply a broad range of

thematic rendering, clustering, and MapTips capabilities.





MapIt for Microsoft SharePoint

Prepackaged ESRI Web part

Build using the ArcGIS API for Microsoft Silverlight

The other client included with MapIt is the ESRI Map Web Part for Microsoft SharePoint. The

Map Web Part is not a developer component. Instead, it's a prepackaged, deployable Web Partconfigured within SharePoint. It's built using an ArcGIS API for Microsoft Silverlight, so it can

take advantage of the rich interactive nature of a Silverlight application.








Includes:

Automated deployment package

Simple administrative interface for configuring map

Choose from an ArcGIS Online or Bing Maps basemap

Add SharePoint lists, ArcGIS Server map service layers, or ESRIMapIt tables directly to the map

Define symbology, custom class break, unique value renderers

The Map Web Part feature includes a SharePoint deployment package and a command line utility

to install the part on a SharePoint site. Once installed, the part provides an administrativeinterface to a Web Part editor who wants to configure the Map Web Part content. You can use an

ArcGIS Online or a Bing Maps layer as a basemap. You can add feature data as operational

layers from SharePoint lists and feature layers in ArcGIS Server Map Services or, as we'll showin this session, MapIt tables.

The configuration of the Map Web Part exposes the ability to modify these operational layers and

change properties, such as transparency, we can define filter definitions, add pop-ups with aliasfields, and construct renderers on the fly.








Includes:

Automated deployment package

Simple administrative interface for configuring map

Choose from an ArcGIS Online or Bing Maps basemap

Requirements:

Microsoft Office SharePoint Server (MOSS) 2007• Enabled with Microsoft .NET Framework 3.5 sp1

• Standard or Enterprise level

The Web Part itself requires Microsoft Office SharePoint Server–MOSS–2007, enabled with the

.NET framework version 3.5 Service Pak 1. We can use this on either Windows Server 2003 or2008, and it's supported on the standard and enterprise level both in 32- and 64-bit OSs.






So in this demonstration I'll go through deploying the Web Part, configuring within SharePoint,

and getting the results.

I'll navigate back to the machine on which I've installed MapIt. Within the MapIt install location

there is a SharePoint folder. The SharePoint folder contains a couple of files of interest. There's aWindows SharePoint solution, which contains the part, we also have a SP config utility, mainline

utility, that we can use to install and uninstall the part onto a the SharePoint site.

There's also a help file, which is accessible via the program menu, which will assist you indeploying, using, and configuring the part. In this case what I'd like to do is deploy the part on a

Web application that I've hosted on this machine. If I navigate out to a command prompt and go

to the SharePoint folder in the MapIt install location, I can specify the SP config utility in thecommand line.

If I specify without parameters, I get a set of help information on the different parameters that arepermitted when using this utility. I'm interested in installing the ESRI Map Web Part onto a Web

application that I've hosted on this machine named Sedona. Now the Web application itself may

contain, and does contain, multiple site collections.

We get instant feedback on the deployment process. The part will be installed and activated on

each site collection. So in the browser, I'll navigate to the Web application that contains a site

collection named DemoSiteCollection that I've created for this demonstration. There's adocument collection that contains a demonstration page, a Web Part page that I can add Web




Parts to. I open this page, navigate to site actions, and click Edit page. This enables me to put inthe Add a Web Part and navigate using the Add Web Parts dialog to the ESRI category, and check

the box next to ESRI Map Web Part.

This will add the Web Part to the page. We can see by default that the map is centered on the

continental United States. It's using an ArcGIS Online layer and includes a collection of layersfrom ArcGIS Online. I can choose between streets, which is the default, topography, or imagery.

Note since it's based on our Silverlight API, we have all of the rich interactive qualities of a

Silverlight application at our fingertips.

What I'd like to do now is start configuring the Web Part so I can add operational layers. I'll

select the edit/modify shared Web Part option. What I'm also want to do is get myself a little

more real estate, so I'm going to change the size of the markup in the browser. What we can seein edit mode is a set of panels, one that allows me to set the basemap, and another one that allows

me to define data sources and add operational layers.

First I'll set the basemap. I have the option of using ArcGIS Online, which is the default, or Bing

Maps production or staging. I have a Bing Maps production account. I'll enter those details here.

As soon as I click OK, I get instant feedback. Note that my request is sent, and behind the scenes

I can see that my map has switched to the Bing Maps roads layer. I click on the globe in theupper left-hand corner; I can shrink the configuration panels and view my map.

Note Bing Maps, like ArcGIS online, has a layer collection that I can choose from. Roads is thedefault, but I can also choose aerial, imagery, or aerial imagery with labels. I'm going to stick

with the roads layer.

I'm going to reopen the configuration panels, shrink the basemap panel, and start working within

my data source panel. By default, any SharePoint list within the current site collection that hasgeoenabled fields will show up. We’ll get back to this in a moment.

First I'd like to add some common geographies that I've added to my SQL Server instance andI've made accessible via my Spatial Data Service.

I'm going to navigate to the Spatial Data Service end point that I created earlier. We'll see the

entry is tagged in the data source panel with Spatial Data Service.

If I expand this panel, I can see a list of databases and tables within those databases. I'm

interested in adding ZIP Codes and in this case, in the Mercator of projection, in the sameprojection as Bing Maps.

Instantly, I'm brought to a configuration panel. This configuration panel enables me to set avariety of options, such as the display name that I'd like to show when users are consuming the

Map Web Part in their layer list. So I'll change this to something a little more intuitive. I'm

actually going to filter for ZIP Codes that are in the state of Oregon, and I'm also going to definepopulation density in just a moment.




For the filter expression, I just want to show those ZIP Codes that show up in Oregon, so I can

specify a field name and a filter value. I'll click Apply, and hide the configuration tabs and zoom

to the operational layer. By default, the symbology for the polygons are the areas that are storedand associated with my ZIP Codes in Oregon are given a default symbol. In addition, a set of

pop-ups or MapTips is also configured and available upon each aerial polygon in a map. We cansee all fields are included by default.

If I select the pop-up tab in the configuration dialog, I can set specific fields that I'd like to show

in the pop-up or the MapTip within the map. In this case I'd like to show ZIP, give it an alias

name that will show up in the MapTip, and also specify population density.

Once I enter the values, I'll note the layer's immediately updated. I'd also like to apply

symbology to the map as it's displayed within the SharePoint Web Part. By default, a simplesymbol for all features is set. I can use the color bar to define different colors, which are actively

updated as I interact with the color selector.

In this case, I'd like to apply a set of value ranges so I have the ability to create a thematic map

with a set of class breaks. I also want to define a field on which to construct those class breaks.

What you'll notice is when I specify the classify by field, it will give me a class breaks slider bar.

By default, I'll have two class breaks. It will spread between the lowest and highest values withinthe field selected. In this case I want to add a couple ranges, so I'll add two ranges, and I'll

specify the class break minimum and maximum values for those ranges.

I can also interact with the slider bar to change the boundaries between the class breaks. If I need

fine detail, I can select the class break, and I can define the value explicitly. In this case, I know acouple of class break values that I'd like to enter, and so I'll select a respective class break within

the slider bar and modify them appropriately.

What we can see on the map is that features are updated immediately. What I also get is a color

ramp selector. So a set of predefined color ramps are created for me. I can define these explicitly

if I'd like, or, for ease of use, I can select a color ramp and have it immediately applied, using theclass breaks that I defined earlier.

As soon as I click OK and accept the changes, the part will show a later collection which

contains any layers or operational layers that I've added to our map. In this case, if I need toreconfigure that layer I can click on it again and open up the configuration panels that we saw

before.

I also have an Add Data button here that takes me back to my Data Source panel. This enables

me to add additional information or additional operational layers to my map. As I mentioned

before, we can add a SharePoint list data to a map.

I have a set of SharePoint lists available in my site collection, one of which contains login sites,

and in all items used created by default. If I select all items, I'm taken into configuration panelsfor the list. One item of note is that a SharePoint list can have address information or




coordinates. Addresses need to be geocoded. Coordinates contain spatial information that enableslist base data to be plotted on the map.

I'm going to select two fields within the list and click the Locate button. In the map, immediately,those locations are plotted. I'd also like to find a more intuitive name for the Web Part end users.

In addition, I want to set a couple of fields that they may find important such aslatitude/longitude and site name. I can also define a more appropriate symbol for my points usingan integrated symbol selector. When finished, I can click OK, and I go back to my configuration

layer list.

What I'd also like to do is to define the initial extent for the map. So when a user opens the WebPart for the first time in a page, he'll be viewing this extent. I'll close my configuration dialogs to

get a better view. When finished editing, click OK or Apply to save the changes.

We'll exit edit mode in the page, and we'll be able to view the part from the end user's

perspective. They have the ability to interact with the features such as the SharePoint list data

plotted on the map and other information, such as population density and ZIP Codes. In this casewe can see that we have a set of login sites that happen to be located quite a distance away from

most of the population centers within Oregon. Note the user also has the ability to change the

base layer.
