How is the name of a service area determined?
The name of the service area polygon is based on the name of the associated facility and the break range; for instance, Graphic Pick 1: 0.0 – 5.0 would represent a polygon that covers all traversable edges within five minutes from the facility, Graphic Pick 1. The unique ID of the associated facility.
Where are the facilities located in service area analysis?
This network analysis class stores the network locations that are used as facilities in service area analysis. The Facilities feature layer has three default symbols: Located, Unlocated, and Error. You can modify the symbology of the Facilities layer in the Layer Properties dialog box.
How to generate lines in service area analysis?
Check Generate Lines on the Line Generation tab of the service area analysis layer’s Layer Properties dialog box. The service area lines feature layer can be symbolized in the same manner as other line feature layers. The system-managed ID field. The geometry of the line, which is stored internally.
How are concentric service areas used in network analysis?
Concentric service areas show how accessibility varies with impedance. Once service areas are created, you can use them to identify how much land, how many people, or how much of anything else is within the neighborhood or region. Finding the network-based service area follows the same workflow as other network analyses.
Where does the service area begin and end?
Right side of vehicle (1)—The service area can begin or end at the facility such that the facility is on the right side of the vehicle. Left side of vehicle (2)—The service area can begin or end at the facility such that the facility is on the left side of the vehicle.
When is a new service area analysis layer created?
When a new service area analysis layer is created, the Facilities class is empty. It is populated only when network locations are added into it. At least one facility is necessary to create a service area. The system-managed ID field. The geometry field indicating the geographic location of the network analysis object.
