Uso
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.
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.
There must be at least two store points in the input store layer for this tool to work.
