topic Converting signed/unsigned 16 bit raster in Data Management Questions https://community.esri.com/t5/data-management-questions/converting-signed-unsigned-16-bit-raster/m-p/701475#M39824 <HTML><HEAD></HEAD><BODY><SPAN>Hello-</SPAN><BR /><SPAN>&nbsp; I have a 16 bit signed .gis raster w/ 1 band (greyscale) cell values displayed as -32,768 through 32,768. I used 'Copy Raster' to convert it to an unsigned 16 bit .img file w/ cell values displayed as 0 through 50,233 (this is the format and cell values I would like). However, when I try to use 'Copy Raster' again on this second file to change it to a signed 16 bit .img w/cell values 0 through 50,233, it reverts back to the old unwanted cell values (-32, 768 through 32,768). How can I get a signed 16 bit .img with cell values 0 through 50,233? Thanks</SPAN></BODY></HTML> Tue, 26 Apr 2011 14:39:26 GMT AlecKretchun 2011-04-26T14:39:26Z Converting signed/unsigned 16 bit raster https://community.esri.com/t5/data-management-questions/converting-signed-unsigned-16-bit-raster/m-p/701475#M39824 <HTML><HEAD></HEAD><BODY><SPAN>Hello-</SPAN><BR /><SPAN>&nbsp; I have a 16 bit signed .gis raster w/ 1 band (greyscale) cell values displayed as -32,768 through 32,768.
