How to change Z-Units on a File Geodatabase Raster?

Discussion created by nbanerjee on Jun 16, 2014

Im thinking this should be easy, but dont see a solution.  I have a raster that stores elevation in feet.  However everytime I use one of the 'functional surface' tools in tool box, such as 'Add Surface Information' it multiplies the values of the cells by 3.281 since it appears to "think" the data is in 'meters'.  I know for a ESRI grid you can manually change the prj.adf text file inside the raster folder, but how do I change this for a file geodatabase?
