GeoDifference Service

Under investigation
Description
 

A GeoDifference Service identifies the difference between two different sets of geospatial data. In the case of vector data, this service would produce a third set of vector data that contains the vectors found in only one of the two sets of geospatial data, and a list of the differences between the polyon attribute tables. In the case of raster data, this service would produce a surface that represents the differences between the raster values.
