Threshold Trade Areas (Business Analyst)
Краткая информация
Creates rings around your stores. The radii of the rings are determined by expanding from the store location until they meet your criteria.

Использование
-
The spatial reference of the output feature class will be the same as the store layer.
-
The store layer input feature class must be point features.
-
In most cases, the store layer input feature layer will be a Business Analyst store layer.
-
Valid numeric units must be used when defining radii values. Negative values cannot be used for threshold radii.
-
Selecting all sites to use will create rings for each point feature in the ring centers (stores) input feature class.
-
In ArcMap, trade areas will only be created for features that are within the active study area or analysis extent.
-
The threshold layer must be a point or polygon feature class and be set up as a Business Analyst Dataset (BDS) layer. In most cases, you should select the block group or block points layer.

ThresholdFeatureLayer |
The input feature class containing the threshold data that will determine the radii. | Feature Layer |
ThresholdPopulationField |
The threshold value field contained in the threshold layer. | Field |
MeasureUnits (дополнительно) |
The units used with the distance values. By default, the units defined in the Business Analyst preferences will be selected.
