I have mosaiced 8 SRTM DEM tiles in order to get one raster layer of elevation. When I use "Mosaic to New Raster" tool I set as a pixel type format "16 bit signed" because this is the format that SRTM uses. When I construct slope/aspect/curvature the raster changes pixel type and from 16 bit signed becomes 32 bit float.
Why does this happen and does it corrupt my analysis?
I use ArcGIS Desktop 10.2.
