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

• 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
