I am using ArcGIS 10 (includes spatial and geostatistical analyst). I have a raster (GRID) with a value range of -167 to 18. I would like to query the raster and create a new one with only the values between -117 and -69. I cannot figure out how to use the raster calculator to do this task. Any suggestions?

You can use the set null tool in the spatial analyst toolbox to assign any cell values outside your desired range to null values. The result will be a new raster layer with only the cell values you wish to preserve.

The expression you should use will be along the lines of:

Value > -117 AND Value < -69

and the false raster should be the same as your input raster, to keep values where the expression evaluates as false.

I do not find the help useful at all unfortunately. I try setting an exclusion range, but do not get the intended results. Not sure what else I can do with this tool. –  Keith Larson Sep 3 '12 at 8:49
