Priority ranks and geoprocessing tools

Priority ranks are used by many geoprocessing tools. Ranking is a way to give greater control to feature classes that are known to have more reliable positions.

There are two sets of tools that use ranks: tools with multiple inputs that explicitly allow ranking to be set, and certain overlay and extraction tools that give a higher rank to the input features over the overlay or extract features.

The geoprocessing tools below allow you to specify ranks for the input feature classes:

The geoprocessing tools below do not allow you to specify ranks for the input features; the input feature class will always be ranked higher than the overlay (clip, identity, symdiff) features. Update is the exception to this rule, as the update features will be given a higher rank over the input features.
