ArcGIS Network Analyst Development Progresses

ArcGIS Network Analyst is a powerful extension for routing that provides a framework for network-based spatial analysis, including location analysis, drive-time analysis, and spatial interaction modeling.

ArcGIS Network Analyst can produce routes with time windows.

Using a sophisticated network data set model, users can easily build networks from their GIS data and dynamically change the analysis of these networks. ArcGIS Network Analyst allows users to model realistic network conditions and solve routing scenarios, such as path, tour, closest facility, and service area.

Scheduled for release 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.

Use ArcGIS Network Analyst to determine

  • Drive-time analysis: Point-to-point routing
  • Route directions: Service area definition
  • Shortest path: Optimum route
  • Closest facility: Origin destination matrix

Network Analyst enhances ArcGIS by adding routing, closest facility, service area analysis, and advanced network management and creation. 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 Network Analyst model, users can do more with their data.

Advanced features of the Network Analyst model include

  • Complex multipart turns
  • Dynamic impedance
  • Global weights
  • Scalable to multiusers
  • Exact and hierarchical routing
  • Network barrier support

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 Analyst 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.
