Introduction to ArcGIS Desktop 2

Although each product serves a unique purpose, there is a great deal of overlap among them. For example:

ArcToolbox can be opened and utilized in both ArcCatalog and ArcMap

Both ArcCatalog and ArcMap can display GIS data and table data

Extensions can be activated in either ArcCatalog or ArcMap

ArcCatalog

Acts as ArcGIS Desktop “Manager”Searches For, Organizes, Creates and

Displays Spatial Data

Creates, Edits and Displays MetadataCan be used concurrently with ArcMap to
