esriNAOutputPolygonType Constants

Options for service area polygon results.

Constant	Value	Description
esriNAOutputPolygonNone	0	No polygons are generated.
esriNAOutputPolygonSimplified	1	Simplified polygons are generated.
esriNAOutputPolygonDetailed	2	Detailed polygons are generated.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server. Requires Network Analyst Extension.

Remarks

The esriNAOutputPolygonType specifies the type of polygon output generated by the INAServiceAreaSolver. The default is to generate simplified polygons as they can be generated quickly by looking at the ends of the traversal results. The detailed method takes longer and will look at the inside of the traversal results to find unreached areas and generate holes in the service area polygon as well as better define the boundary of the service area.

esriNAOutputPolygonsNone - No polygons will be output.
esriNAOutputPolygonSimplified - Simplified, faster to generate, polygons are created by this option.
esriNAOutputPolygonDetailed - Detailed, with holes in the service area as well as better boundary, but slower to generate, polygons are created by the option.
