Scheduled for release with ArcGIS 9.1 in the first half of 2005, ArcGIS Network Analyst enables ArcGIS users to solve a variety of problems using geographic networks. Tasks, such as finding the most efficient travel route, generating travel directions, finding the closest facility, or defining service areas based on travel time, become greatly simplified.

In ArcGIS Network Analyst, warehouses and their individual drive times are displayed along with a demand point. Using the Closest Facility function, the closest warehouse to the demand point is identified.

Included with 9.1 (previously 9.0.2), Network Analyst enhances ArcGIS by adding advanced network management and creation. ArcGIS Network Analyst can be used for a range of problems from classic point-to-point routing to advanced time-based delivery models across millions of features. By using the advanced features in the new ArcGIS Network Analyst model, users can do more with their data.

Network-based spatial analysis is available for ArcGIS Desktop (ArcView, ArcEditor, or ArcInfo), ArcGIS Engine, and ArcGIS Server. For desktop users, ArcGIS Network Analyst provides a rich environment with easy-to-use menus and tools, as well as the robust functionality available in the geoprocessing environment for modeling and scripting. ArcGIS Engine and ArcGIS Server users can employ the application program interfaces of the optional Network Extension to provide customized network solutions.

ArcView 3.x Network Analyst users will find all their familiar tools available in ArcGIS Network Analyst. In addition, ArcGIS Network Analyst has improved the core functionalities and added new features. ArcGIS Network Analyst requires ArcView, ArcEditor, or ArcInfo.
