Enumeration Type Documentation

◆ AGSServiceAreaOverlapGeometry

Type of overlap between service area geometries.


Creates individual polygons for each facility. The polygons can overlap each other. For overlapping lines, portions of the network that are within reach of more than one facility will have a line for each facility.


Merges the polygons of multiple facilities that have the same cutoff values into one polygon. If the polygons of a given break value don't touch, they are nonetheless merged into one multipart polygon. This option does not apply to lines.


Creates individual polygons that are closest for each facility. The polygons do not overlap each other. For split lines, none of the lines overlap each other, and a line is always assigned to the nearest facility even if more than one facility can reach it.

◆ AGSServiceAreaPolygonCutoffGeometry

Type of geometry for concentric service areas.


Output polygons extend between the nearest cutoff values only. They do not include the area of smaller breaks. This creates polygons between consecutive breaks.


Output polygons extend from the facility to the cutoff. If you create 5- and 10-minute service areas, the 10-minute service area polygon will include the area under the 5-minute service area polygon as well as the area from the 5-minute to the 10-minute area.

◆ AGSServiceAreaPolygonDetail

Level of detail for service area geometries.


Prefers higher-order edges to the lowest-order edges in the transportation network, for example primary roads, then secondary roads, and finally local roads in that order.


Polygons are generated quickly and are fairly accurate, but quality deteriorates somewhat as you move toward the borders of the service area polygons. Outputting standard-detail polygons may result in islands of unreached network elements, such as roads, being covered.


Most detailed polygons. Holes within the polygon may exist; they represent islands of network elements that couldn't be reached due to travel restrictions for example. Expect high-precision polygons to take the longest amount of time to generate.
