    Provide checks to ensure that Spatial analyst functions that depend upon projected coordinates are indeed valid.

    For example, calculating slope using a grid in decimal degrees and Z values in meters, provides erroneous results.  Given the number of posts on this and related issues, please fix it.  check for projected coordinates for all Spatial Analyst functions that require planimetric data.
