New types of analysis are possible because it can be used to model raster data, in addition to the vector data ArcView GIS already supports.

ArcView 3D Analyst enables users to create, analyze, and display surface data. This generic surface modeling package is ideal for both the novice and the advanced user, its functionality answering the needs of those performing tasks related to surface analysis and display. Unique features of ArcView 3D Analyst include support for triangulated irregular networks (TINs) and simple three-dimensional vector geometry, as well as interactive perspective viewing.

The ArcView Network Analyst extension enables users to solve a variety of problems using geographic networks (i.e., streets, highways, rivers, pipelines, electric lines, etc.) such as finding the most efficient travel route, generating travel directions, finding the closest facility, or defining service areas based on travel time.
