010209 : <value> and <value> have incompatible projections.

Description

The input geodatasets have incompatible projections, and the Spatial Analyst tool cannot be used with them.

Solution

Either project one of the datasets to be the same as the other, or project them both to a mutually compatible projection. Use the Project Raster or Project tools to project the data. Use Project if you are using a coverage dataset.
