What’s Happening…
1. Going to go over the differences
between ArcView 3.x and ArcGIS
2. Introduce a new data container
called a GeoDatabase
3. Then you are going to…
a) Download an ESRI on-line course
b) Download the data for that course
c) Do two of the exercises in that course
2
Objectives of Ex 1
• Familiarize you with the ESRI on-line
courses
• Familiarize you with the differences
between ArcView 3.x and ArcGIS
3
The Challenge
• You know how to use ArcView 3x
• The world is going to ArcGIS, now in
version 9.2
• ArcGIS can do everything ArcView 3x
could do …
• And MUCH MORE!
• The price you pay is complexity
• Which is not necessarily good from your
point of view
4
Two basic things…
• There is no such thing as an Active
Theme!
– All layers are active unless turned off
• When in doubt, Right Click!
5
Terminology is Different
ArcView 3.x
Project (.apr)
View
Layout
Theme
Grid

Select by Attribute
Select by Theme
Select by Location
Table Link
Table relate
*Layer
Has two meanings (1) Like a theme, (2)
Also means a Symbology file like a .avl but
has extension .lyr and has no data!
7
In ArcView…
• You could…
–
–
–
–
Add themes to the view
Change symbology of themes
Re-order the themes in the Table of Contents
Carry out many operations on the themes
• Select by attribute or location
• Overlay themes to make new themes
• Etc.
– Make maps from themes
8
And in ArcGIS…
• You can do the same things in ArcMap!
• Let’s compare the old ArcView user
interface with the new ArcMap user
interface
• But first
– ArcMap comes in three license levels
ArcView
ArcEditor
More Power – more $
ArcInfo

ArcGIS in General…
• Can do the same kinds of things as
ArcView
• The interface is different and the
terms used are different
• Two things to remember
– No such thing as the “Active Theme”
– When in doubt, Right click

Many Tool Bars;

and
Data or Map mode
13
Basic Tools etc.
• Add data
• Open Toolbox
• Zoom in
• Open Catalog
• Zoom out
• Find
• Zoom to full Extent
• Pan
• Select Feature
Info
• Arc Length
• Remember the tool
tip lower left
14
Layout view
• The Layout view
is where you
make maps
• It is very easy to
go back and
forth between
the Data and
Layout views
15
Data Management
• When you moved data in ArcView3x
you had to be sure that you got all
the shapefile files
• Pain!
• So ESRI provided a second software
called ArcCatalog
• In ArcCatalog you can copy and paste
data without having to worry about
missing some of the files
16
In ArcCatalog you can….
• Manage data
• Preview data
– Geography
– Attribute table
• View Metadata
• When you find the data you want you
can just drag it into ArcGIS!!!
17
ArcCatalog
18
Loading data
• Data can be
–
–
–
–
Shapefiles – even ArcView 3 shapes
Various kind of images
Rasters
Coverage (older file type)
• And can be either stand-alone data …
• Or be in a new container called a
GeoDatabase (GDB)
19

21
GDB
• GDBs are not hard to use
• They are hard to build
• You can drag them around in Windows
Explore with impunity
• More and more data is delivered in
GDB
• Consider GDBs and FDSs to be
folders
22
Views of data in Catalog
• The Contents
View
• Name
• Type
• Symbol
23
Views of data in Catalog
• Preview of
Geometry
24
Views of data in Catalog
• Preview of
Attribute table
25
Views of data in Catalog
• Metadata
– Description
– Spatial data
• Projection
• Datum
• Linear unit
– Attributes

Other Advantages of ArcGIS
• Project on the fly
– That means you don’t have to mess with
projections and datums!
– But only works if there is a .prj file
• Automatic ordering of data in the TOC
– Points at top, lines in middle, polys at bottom
• Right Clicking!
• Properties
30
Booby Traps
• Never, Ever have a space anywhere in
a path to ArcGIS data or project!!!!
• Use “_” as a spacer not “-”

OK

Exercise 1
• Your have 2 documents
– Print out of the course
– A document describing how to download and
store data
• Demo of
–
–
–
–
accessing ESRI’s virtual campus
Downloading a course
Downloading the data for a course
Doing two exercises
• #2 and #3
