Summary
Generates trade areas based on standard geographic units.
Learn more about how Create Trade Area From Geography Levels works
Usage
-
The spatial reference of the output feature class will be the same as the input geography boundary layer.
-
Use the Append Fields From Geography Boundary to Output option to include the demographic data of an ESRI dataset in the output trade areas.
-
The Table Containing Matching Geography Fields must be in a format compatible with ArcMap. Your tabular data can be in the form of a database file format (.dbf) file, a comma- or tab-delimited text (.txt) file, or a relational database management system (RDBMS).
-
All nonmatching ZIP Codes will be excluded in the output trade area.
-
Nonmatching ZIP Codes are ZIP Code records in the Table Containing Matching Geography IDs that are not valid and do not have a corresponding feature in the input geography boundary layer.
-
If you want to select from a list of available geographic features to create a study area, you can use the Trade Area wizard in ArcMap. Selecting geographic features is not available as a geoprocessing tool.
-
In ArcMap, trade areas will only be created for features that are within the active study area or analysis extent.
