Краткая информация
Creates a feature class of network distance trade areas that expand around point features until criteria is reached.
Использование
The size of output polygons is determined by the Threshold Values parameter value provided for a selected Threshold Variable parameter value from the Business Analyst dataset.
Multiple threshold drive time polygons can be created around each input by typing individual values into separate threshold value text boxes.
The ID Field parameter uniquely identifies the point location around which threshold drive time polygons are created.
