ArcGIS Desktop Extensions
ArcGIS Desktop products (ArcView, ArcEditor, and ArcInfo) are engineered with a common architecture and a shared extension model. This extension model includes a wide-ranging suite of optional tools that can dramatically expand the functional capabilities of these products with specialized geographic information system (GIS) tools.
This brochure can be used to help clarify these optional extensions and their potential use within an organization, or applied to specific data models or scenarios.
