I've attached the raster, in two versions. The one ending in 'I' is an integer raster, the one in 'F' is floating point. Neither one works for me in Raster Calculator. thanks for your help. Jeff

Jim, I tried running statistics on both rasters, and got the same result when running mosaic, so my problem hasn't changed. thanks Jeff

When I try to use the raster calculator (in ArcToolBox or as a command tool), I get a runtime error. The error messages are shown below. And yes, I have a license for Spatial Analyst, but I seldom use it, so its quite possible that I am doing something obviously wrong. The output raster, test02 does not exist yet (I tried pre-creating it, but that didn't work, either). The input raster is integer, but float rasters are not working for me either.

When I use the mosaic tool to combine two or more integer (or float) rasters, originally DEM's, the value ranges (elevation) change. For example, one raster has a range of values from 1189 - 1513, the other 1215-1557. I expect the mosaicked raster to range from 1189-1557. But, instead, I get a value range of -32768 to 32767. So, the mosaicked raster is useless to me.
