I have a raster (a DEM) in GRID format, source type = continuous, pixel type = floating point, 32 Bit. The field names do not display when I attempt to use this raster in Extract by Attributes tool, nor when I select Properties > Fields of this raster. Does the Extract by Attributes tool not work with floating point data? I got this to work by using raster math INT function but this truncates decimals. Is there a simple workaround other than multiplying raster values by, say, 1000 (to keep three decimal places of value)? Thanks.
