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
3
office.

TOC – 3 flavors
• Display Tab
– Allows you
to
manipulate
the data
– And change
layer
position by
dragging
This is usually where you
want to be!

TOC – 3 flavors
• Selection
Tab
– Shows
which
layers are
selectable
– And you can
change that
right there
By default ALL are selectable and
that can be a booby trap that can
get you into trouble in many ways!

. 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

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
20
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
21
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)
22
Adding Data
• Directly from ArcMap
• Drag from ArcCatalog
23
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
24
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!
25
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
26
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!
