Data formats
• ArcInfo Coverages
– info directory
– multiple files
• ArcView Shapefile
• Many import formats
• Output to printer, file, image etc.

ArcView Shapefile
• Triplet of files, *.shp, *.shx, *.dbf
• Shapefile “counties”
– Counties.shp - points, lines, areas
– Counties.shx - index file
– Counties.dbf - attribute file
• No topology stored!
• .zip versus .e00

ArcView Components
• Project: collective storage for maps,
charts and tables
• View: display set for geographic data
• Theme: One attribute or data layer,
part of a display
• Table: spreadsheet-type flat file of
attributes and records

ArcView: Project, View,
Theme, Table

ArcView Components (2)
• Extension: An extra part of ArcView for
specific enhancements, e.g. Spatial
Analyst, GridHandler.
• Layout: Full set of properties, settings,
and components that generate a specific
map
• Chart: “business graphic” display of data
in a table
• Script: a program written in ArcView’s
programming language called “Avenue”

ArcView is WIMPy!
Geo 265, GIS Practicuum
The WIMP Interface
• Windows: Multiple, scroll, resize,
elevator bar
• Icons: Represent windows, tasks, etc.
Can use drag and drop, click to
activate etc.
• Menus: Pop-up, pull-down, pull-right.
Messages
• Pointers: Mostly the mouse. Can use
digitizer, track ball etc.

ArcView: Active Window
Geo 265, GIS Practicuum
Windows: The active window
• Projects, views, tables, charts,
layout, and scripts all have their own
windows
• Only one window is “active” at a time
• To make a window active, click on it
or select it from the menus
• The title bar will be highlighted in
color when the window is active

Icons: Buttons vs. Tools
• Buttons - top layer of icons
– Push once, something will happen
• Tools below buttoms
– Must do something with mouse to make
something happen

Helpful Techniques...
• OVERLAY
– integrates 2 or more layers to create a
new layer
• BUFFERING
– creates new features (polygons) from
existing features
• CLIPPING
– extracts and/or deletes features from one
layer that overlap with another layer
