Resumen
Creates trade areas that approximate the size, shape, and area of existing polygons using available routes from the selected distance type.
Uso
The Output Feature Class attribute table contains a field that lists the distance or travel time of each polygon from centroid to boundary.
If the Store Layer parameter is specified, its locations will be used as the starting point for creating network service areas, instead of the input centroids.
The Iterations Limit parameter allows you to reduce credit consumption for online data by restricting the number of times networks can be traversed. A low Iterations Limit value may impact how closely the drive time trade areas align with the input polygons.
