May 10, 2017 at 1:25 | comment | added | fatih_dur | I think I have found the issue, just my ignorance. In the same help page references in the question, there is only one option for Floating data, which is Floating-point 32 bit. Obviously if ArcGIS sees a float raster is coming, it sets the depth 32 bit automatically. Most probably I need to scale up/down my float values and round to nearest integer to avoid this issue. | |
May 10, 2017 at 1:21 | comment | added | fatih_dur | @ahmadhanb, Most probably this is related to the overall mechanism of Spatial Analyst or Raster Processing toolsets, somehow it promotes the depth. Thanks for the hint anyway. | |
May 10, 2017 at 1:04 | comment | added | ahmadhanb | As far as I know, if you clip the raster using a feature class, the output will be a raster depth with a pixel depth of 32 bit even if the raster pixels values can be within 16 or 8 bit pixel depth. The problem might be due to the clipping of raster image rather than the raster calculator. | |
