ArcView 3.1/3.2
An Overview
As of January 2000, ArcView 3.2 was superceded by ArcGIS 8.
The term ArcView was applied to the lowest level tier of ArcGIS 8.
Progressively higher tiers, all with a common interface, were termed
ArcEditor and ArcInfo

Arcview Components
• projects
• tables
– all components associated with
a particular undertaking
– comprised of views, tables,
charts, layouts, scripts
• view
• chart
– essentially a map which you
look at or view
– contains one or more themes
– business graphics to display
geographic and tabular data
• layout
• themes
– layers of spatial data with
similar characteristics (eg
streets, hydrolgy, capitals)
– in ARC/INFO called coverage
if vector, grid if raster
7/12/2016 Ron Briggs, UT-Dallas
– rows (usually geographic locations,
linked by ID to theme features)
– columns describe attributes
(characteristics) of locations
– graphic output/screen display of
views, tables, charts
• script
– automation feature written in
Avenue which allows full
customization

Arcview Components:
Projects
• Project (workspace)
– all components (‘documents’)
associated with a particular
undertaking
– stored in file with extension .apr
– components dynamically
updated: change one part, other
parts updated accordingly.
– reopens in identical form to
when closed
– five types of documents
available: views, tables, charts,
layouts, scripts
– each document has a set of tools
for working with it

ArcView Components:
Views & Themes
•
•
•
•
•
a view is essentially a map which
you look at (view) on the screen
(or print with layout)
it contains one or more themes
(ARCINFO coverages/grids)
which are layers of spatial data
with similar characteristics eg
streets, hydrolgy, capitals
only one view active at a time
themes listed in ArcView Table of
Contents which allows you to
control themes to be viewed
themes are added from View
window using View pull down
menu

GIS Framework
roads
hydrology
topography
Data is organized by layers,
coverages or themes
(synonomous concepts), each
representing a common feature.

ArcView Components
Tables & Charts
•
•
•
•
•
•
contains attribute (descriptive) data
can create in ArcView or access data
from other sources (e.g via SQL)
references to tables are stored, not data
itself (therefore automatic update)
event tables contain geographic
references and can be mapped (nonevent tables can simply be included in
layouts)
charts can be used to display tabular
data.
6 types: area, bar, column, line, pie,
scatter
Area
Bar
Column
Line
Pie
Scatter
Since data is stored in dBase tables and Excel can read these, it’s often as
easy to use Excel (or similar) for graphing, especially for “one-off” charts.

Data Types in basic Arcview (3.2)
[others available via standard (free) or optional (extra $) extensions]
Vector (spatial)
– shape file: ARCVIEW’s native format
(object database model)

– x,y coordinates defining lines, points,
polygons
Tabular (attribute)

Using Extensions and Scripts in ArcView
• Obtain copy of script or extension
– Write yourself with Avenue language
– Supplied with ArcView in folder: arcview/samples/scripts or
arcview/samples/ext
• Go to ArcView Help/Contents/Sample Scripts and Extensions for documentation
– Buy from ESRI and other companies
– Supplied free by ESRI or users and available on ESRI web site at:
http://gis.esri.com/arcscripts/scripts.cfm (also includes extensions)
• or go to www.esri.com and click Support/Downloads/ArcScripts
• Be sure to print or download documentation/description
• To load and use an extension
– Place .avx file in arcview/ext32 folder
– Open ArcView, choose File/extensions, place tick next to name, click OK
• To load and use a script
In Project window, select Script and click new button to open script window
Use Script/load text file to load code from existing text file containing avenue code (.ave)
e.g. \av_gis30\arcview\samples\scripts\calcapl.ave
will calculate areas, perimeters, lengths
Click the “check mark” icon to compile the code.
Take steps within ArcView as appropriate for specific script
e.g. Open a View and be sure the theme you want processed is active.
Click on script window then click the “Runner" icon to run script.
e.g. variables measuring area and perimeter will be added to theme table
Will be covered
in later classes.
