Scenarios for using the PAAT

There are four main scenarios when using the Positional Accuracy Assessment Tool (PAAT) tool to assess positional accuracy: using two feature classes, a feature class and a raster, two rasters, and a z-enabled point feature class and digital elevation model (DEM) raster or triangulated irregular network (TIN). The different combinations of layers for evaluation and reference cause the PAAT session to be variable based on what you are using as an evaluation layer versus a reference layer. For example, using two feature classes creates a grid on the reference layer, but if you are comparing a z-enabled point feature class to a DEM, the grid does not appear.

The scenarios and their respective behaviors are as follows:
