Course Stuff…• There are now 45 of you!• So I have to change some things

1. Each week when you hand in A. Quiz from moduleB. Exercise I assign

2. You will add a reflection page for the WEEK

3. You will put The week #, your name, Your Class (357 or 557) on the back, upper right of the reflection page.

4. This does not apply to this week.

MORE• There is a fairness question –• Some have lab Tuesday and some Friday• Yet things have to be turned in on

Tuesday• BUT: since labs are help sessions and

since usually they are only 20% full (after the first couple of weeks) anyone can go to any lab.

• SO DON’T WAIT TO FRIDAY TO WORK – START EARLY

• Tuesday night stays the turn in day (Actually Wednesday AM @ 8:00 is when I take things out of the box outside my office.

You can move them around.

In fact, you can move them right off the ArcMap Window

TOC – 3 flavors

• Display Tab– Allows you

to manipulate the data

– And change layer position by dragging

This is usually where youwant to be!

15

TOC – 3 flavors

• Selection Tab– Shows

which layers are selectable

– And you can change that right there

By default ALL are selectable andthat can be a booby trap that canget you into trouble in many ways!

• Source Tab– Allows you to

manipulate the data

– Shows path to data

– Cannot change layer order

17

. M?? things• In the previous slide the San Diego

data was stored in a GeoDatabase

• I can tell this from the symbol and from the extension (mdb) on the file “folder” that contains the layers

• The .mdb folder = a GeoDatabase• The other .M thing is the .mxd or

map document

18

GeoDatabase?

An object-oriented data model introduced by ESRI that represents geographic features and attributes as objects and the relationships between objects but is hosted inside a relational database management system. A geodatabase can store objects, such as feature classes, feature datasets, nonspatial tables, and relationship classes.

All in one chunk!

Identification

• There are several ways of identifying features (and this is related to selecting)– Use the Drawing toolbar selection

tool to display a “map tip” if one exists

– Use the Identify tool to display the record of data for that object

– Select the feature and look in the attribute table for info

21

Selection• Selection is a way of focusing the

system’s attention on a specific feature (object) or set of features

• There are several ways of selecting– Use the selection tool

The feature will get a strange aqua color or outline. The record in the attribute table will be colored aqua also

– You can shift-Click to select a number of features

– You can select a record in the attribute table and it will also be selected in the dataview

22

More Selection

• Under the Selection menu there are a number of options– Select by location (select features

from one or more layers based their spatial relation to features in another layer)

– Select by Attribute (select features based on data in the attribute database)

23

Adding Data

• Directly from ArcMap• Drag from ArcCatalog

24

ArcCatalog

• Is a very handy application• In Exercise 1a you will see that a

shapefile is composed of 3-~8 files• And thus is hard to move because

you always leave something behnid• In ArcCatalog, however, it appears

as one file and you can move, rename, etc much easier

25

ArcCatalog (cont)

• Booby trap – sometimes if you are working with data in ArcCatalog you cannot add it to a map because Catalog is using it

• Solution – close ArcCatalog• Point – this is not a ESRI thing but

is due to Windows not liking two apps working with the same data at the same time!

26

ArcCatalog (more yet)

• ArcCatalog is very handy because you can preview data before you load it into ArcMap

• You can look at– Contents (name, Type, Symbol– Preview

• Geographic data• Table data

– Metadata

27

Avoid Booby Trap

• You should always manage your data in ArcCatalog and NOT in Windows Explorer.

• In ArcCatalog shape files are represented by one file

• In Windows Explorer shape files are represented by 3 or more files

• Too easy to miss one if moving files around!
