The Custom Geographic data type is used for records that have been grouped into custom territories. This allows data from each territory to be credibility weighted with data from nearby territories, using Variable Gradient Geospatial Smoothing.
MultiRate can group records using latitude and longitude data (this can be done with the Create New Territory Column tool) or they can be grouped into territories by the user (see User Defined Territories).
If the territories are created by MultiRate or the user creates a Map Data Table, an approximate mapping of the the resulting Custom Geographic factors can be viewed in the Result Inspection Panel if the computer has Microsoft MapPoint installed.
**Note: This map is created by displaying the factor for each Territory in all of the ZIP Codes whose centroid is contained in that Territory. As a result, the outlines of territories on the map will be approximate. An example of this can be seen below.**
