DESCRIPTION
Autodesk uses Feature Data Objects (or FDO) technology to manage live data connections to geospatial data, eliminating the need to import or export data. It allows AutoCAD Map to combine the analysis benefits of GIS software with the flexibility of CAD software.

Welcome
Richard Chappell – “Rick”Geospatial Application EngineerCADsoft Consulting, Inc1295 W. Washington St., Suite 201, Tempe, AZ 85281480-820-0408 [email protected]://www.cadsoft-consult.com/blogs/geo/http://www.linkedin.com/in/richardchappell
Objectives
Participants to gain a basic understanding of FDO To be able to basic FDO connections in AutoCAD Map 3D 2010 To be able to filter FDO feature sources To be able to stylize FDO feature sources
Agenda
Discuss FDO What it is Where it came from What it means to us Hands on Examples of working with
AutoCAD Map 3D 2010 to connect and manage FDO feature sources
Tell us who you are
Name What do you do Experience with Autodesk products Why you’re here
What is FDO?
The FDO Standard is maintained at OSGeo
Where did FDO come from?
Autodesk needed a technology that could provide a way to access many different geospatial data sources through a common mechanism.
Requirements object-based feature model Supports the OGC Simple Feature specification geometry types Defines a logical model that maps to commonly used physical
implementations Each data source has its corresponding FDO provider. Allow clients to determine specific capabilities of a particular
provider Allows new commands and schema additions to be easily added
over time

AutoCAD Map 3D
AutoCAD Map 3D uses FDO technology to create a hybrid environment with geospatial features and drawing objects
There are 3 main types of feature sources: File-based raster and vector (SHP, SDF, DEM, SID, ECW,etc) Database vector and ODBC (Oracle, Access) OpenGIS raster and vector (WMS, WFS)
Feature sources render very rapidly
Feature Source – Raster (Mr Sid)
Feature Source – Raster (DEM)
Feature Source – Vector (Shape)
Feature Source – ODBC (Access)

Feature Layers
Process Connect to a feature source Can be a single file or folder Give it a name Adjust settings (coordinates)Feature source is added to Map Explorer Add to MapFeature layer is now added to Display Manager.
Map Overview
Hands-On Exercise – Connect to a Feature Source
Open redding.dwg Ensure Display Manager is selected in the Task Pane (If task pane is not up, type mapwspace) Click Data>Connect to Data Click Add SDF Connection Give it a name – SDF_Parcel For source file, select parcels.sdf In the Add Data to map area: Ensure parcels schema is selected Note coordinate system is CA-I Click Add to Map
Hands-On Exercise – Connect to a Feature Source
Add another SDF connection Name – SDF_ROADS Source – Roads.sdf
Under Add Data to Map Ensure Roads Schema is selected Click Add to Map
Add Shape Connection Name – SHP_Waterlines Source – waterlines.shp Click Connect
Under Add Data to Map area Ensure waterlines schema is seleected Click Add to Map
Close Data Connect Window
Hands-On Exercise – Connect to a Feature Source
In the Display Manager, select the waterlines layer. Click the Table button (at top of Task Pane) In the Data table dialog box, select any record – note the map zooms to the
objects selected in the Data Table.
Hands-On Exercise – Add Point Data (ODBC)
First, we need to serve a database as an ODBC connection
In Windows, clisck Start>Run Enter ODBCAD32 Click OK
In the ODBC Data Source Administrator Dialog box, clixk System DSN Click the Add button In the Create New Data Source dialog box, under Name, select Microsoft Access Driver (*.mdb) Click Finish
In the ODBC Microsoft Access Setup dialog box, for Data Source Name, enter REDDING_ODBC Click Select
Browse to redding_hydrants.mdb Click OK
Click OK to complete the ODBC setup
Hands-On Exercise – Add Point Data (ODBC)
The next step is to add ODBC Data to the Drawing as a feature source Use the same process to Connect to Data and Add ODBC Connection Name – ODBC_Hydrants Source Type – Data Source Name (DSN) Redding_ODBC Click Connect
Click Login Under the Add Data to Map: Click Edit Coordinate Systems tab Click the Default Spatial context Click Edit
In Select Coordinates System dialog box Category – Lat Longs Coord System – LL, No Datum, Latitude-Longitude; Degrees -180 to +180 Click OK
Hands-On Exercise – Add Point Data (ODBC)
Under Add Data to Map For X, select LON For Y, select LAT For Z, select <none>
Click Add to Map Close the Data Connect Box
Filtering Data Sources
By Attribute STNAME = Brittany Drive
By Location
Hands-On Exercise – Query Features on Connect
Use an Attribute Filter Connect to SDF feature source Name – SDF_PARCELS_BRITTANY_DRIVE Source – parcels.sdf Click connect Under Schema, ensure Parcels are Checked Click the down arrow next to Add to Map Select Add to Map with Query In the Create Query dialog box, click Property > STNAME Click the Equal To button
Hands-On Exercise – Query Features on Connect
Click Get Values Under Select a Property to Retrieve Its Values, select STNAME Under Filter the List of Values, enter: BR Click the green arrow button Click Brittany Dr Click Insert Value In the Create Query dialog box, click OK
To see the filtered parcel feature source, turn the other feature sources off in the Display Manager
Hands-On Exercise – Use a Spatial Feature with a SHP
Create a new data connection Name – SHP_VALVES_BRITTANY_DRIVE Source – valves.shp Click Connect Under Schema, ensure Valevs are checked Click Add to Map with Query In the Create Query dialog box, click Locate on Map>Inside
Rectangle Create a rectangle around the filtered parcels In the Create Query dialog box, click OK Close the Data Connect window
Valves are filtered within the rectangle
Hands-On Exercise – Stylize the Features
Turn on all of the feature layers At top of Task Pane, click Groups and select Draw Order Drag roads above parcels, and hydrants above roads In the Display Manager, select the Hydrants layer and click the
Style button Under Scale ranges for Layer, set the To scale to 5000 In the Style editor pane, click the Style Browse button In the Style Point dialog, click the Symbol browse button Browse to, and select water-hydrant.dwg Click on the WATER symbol Click OK
Hands-On Exercise - Stylizing
Add themes and styles to feature layers
Tell us how we did
