Using ArcGIS (Map/Catalog) 10.0. I have a raster file (kdens) developed from point data using the kernel density tool. It is 32-bit float file format. I need this file converted to a polygon shapefile. (Note I have used the Math/Times tool to preserve the decimal units in a new raster: kdens100K). Using the copy raster tool, I have specified the output raster to 32-bit unsigned. However, the output raster is identified as a 16-bit signed when I check the raster properties and the raster values are truncated to match the 16-bit value range.

Any insight into to why the output is being formatted to 16-bit signed when I specify 32-bit unsigned?

    That is unusual. Why are you copying it? If you already have it as a raster... are you changing format? Are you certain the 'to' format supports UInt32 pixel format? i.e. what format is 'from' and what format is 'to'.

  • Raster has to be of integer type if you want to convert it to polygons. Copy raster tool lives in it's own world – FelixIP Apr 23 '15 at 1:32
