Area Task Info
Default impedance cutoffs. Cutoffs specify the quantity of the impedance to apply. They constrain the extent of the service area to be calculated. For example, if you apply breaks of 5, 10, and 15 when the impedance is set to Time, the service area will include those streets that can be reached within 5, 10, and 15 minutes.
Geometry at cutoff. Specifies the behavior of service area output for a single facility when multiple cutoff values are specified. This parameter does not apply to line output. Default value ServiceAreaPolygonCutoffGeometry.Rings will be returned on error.
Maximum locating distance is the furthest distance in meters that Network Analyst searches when locating or relocating a point onto the network. The search looks for suitable edges or junctions and snaps the point to the nearest one. If a suitable location isn't found within the maximum locating distance, the object is marked as unlocated.
Polygon buffer distance. The polygon buffer refers to the distance from the road the service area polygon should extend when no other reachable roads are nearby, similar to a line buffer size. This is useful if the network is very sparse and you don't want the service area to cover large areas where there are no features.
Polygon detail. Specifies the level of detail of the output polygons. If your analysis covers an urban area with a grid-like street network, the difference between generalized and standard polygons will be minimal. However, for mountain and rural roads, the standard and detailed polygons may present significantly more accurate results than generalized polygons. Default value ServiceAreaPolygonDetail.Standard will be returned on error.
