• Shapefile “counties”– Counties.shp - points, lines, areas– Counties.shx - index file– Counties.dbf - attribute file

• No topology stored!

• .zip versus .e00


ArcView and Extensions• ArcView 3.x

– Spatial Analyst– GridHandler– ChartViewer– Network Analyst– 3D Analyst– ArcView Internet Map Server/ArcIMS– Support Products, e.g. Manuals, CD-ROM


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

ArcView is WIMPy!

elevator bar

• 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

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


Buffering...


Clipping (cookie cutting)...


Analysis or “Geoprocessing”


Working with wizards Explanation & guidance

Not just new users

Helpful graphics

Smart defaults!

This is the Buffer wizard

One operation at a time
