ArcGIS Network Analyst

The ArcGIS Network Analyst extension expands the core capabilities of ArcView GIS software by providing network-based spatial analysis tools. Users can build multimodal routes, provide travel directions, look for closest facilities, and create service areas and origin-destination cost matrices. They can solve vehicle routing problems that include turn restrictions, speed limits, height restrictions, and traffic conditions at different times of the day.

This donation from ESRI includes ArcGIS Network Analyst for one user.

Here are some notable features of this product:

• Routes can consider barriers, such as closed streets.
• Service areas can be based on either driving time or driving distance.
• Network maps can be overlaid with other data layers to reveal relationships not otherwise apparent.
• Driving directions can be shown as text, overview maps, turn-by-turn maps, or stop vicinity maps.
• Introduction to ArcGIS Network Analyst is a free online training course available to anyone on the ESRI website. It shows how the extension solves various problems and explains how to create simple and multimodal network datasets. It takes about one hour to complete.

Additional Eligibility Requirements:

Recipient organizations must already have and use single-user ArcView or ArcEditor software or else request ArcView concurrently with this extension. Because this extension is advanced software, ESRI requires prospective recipients to submit a written statement describing their advanced needs, demonstrating an understanding of the core capabilities of the general products, and describing the specific capabilities of the advanced products needed for their intended tasks. These statements will be reviewed by ESRI, who may request further details or clarifications.

ArcGIS Network Analyst Software:

ArcGIS Network Analyst adds these capabilities to those of ArcView:

• Routing: Develop routes that consider time windows, driver breaks, and vehicle capacities.
• Service area analysis: Generate complex polygons; allocate service across networks.
• Closest-facility analysis: Route according to fixed and mobile assets; plan for emergency response.
• Driving directions: Create expandable inset maps; enable auto-generation.
• Modeling realistic network conditions: Create models that encompass such attributes as distance, time, visibility, multipart turns, dynamic impedance, and hierarchical routing.
• Multimodal networks: Model multiple forms of transportation across a single dataset by using points of coincidence, such as rail stations or bus stops, that form the linkages between several different forms of transportation.

More details and links to case studies can be found on the ESRI website to help in evaluating whether this product is what is needed.
