ArcGIS Network Analyst: An Introduction
ArcGIS Network Analyst: An Introduction
• Find the area you can reach from a facility
- Solve for many facilities
- Use multiple break values
- Specify the direction of travel
- Output lines or polygons
- Analyze for different times of the day
Service Area solverperforms coverage analysis
Use the Service Area solver to
find coverage for fire stations

- Breaks
- Maximum hours
- Time windows on orders
Vehicle Routing Problem solverperforms fleet routing
ArcGIS Network Analyst: An Introduction
• Find the nearest facilities from
each incident
- Limit the search distance
- Limit the number of facilities to find
- Travel from the facility to the incident
Closest Facility solverfinds the nearest location
Find the nearest emergency vehicle to
an incident
