Yes, you can then export it. IMAGINE (.img) is generally the most stable for large rasters in my experience. — Jarlath O’Neil-Dunne University of Vermont | Spatial Analysis Lab > On Mar 25, 2015, at 3:39 PM, Christi Ludlow Townsend <[log in to unmask]> wrote: > > Jarlath, > > Can I then export the hillshade as an actual file?

I've mosaiced the tiles into four hemisphere-wide rasters (16-bit signed integer). I am running each mosaic through the ESRI 10.2 Hillshade tool which outputs 8-bit unsigned files.

ESRI directions say to use a reclassify or extract by attribute to separate non-zero values. Thing is, most of the resulting hillshade pixel values are non-zero so not much area would be made transparent by creating such a file. > > Any ideas? > > It seems that much of the support documentation assumes you want to use mosaic datasets which I cannot in this case. > > Many thanks, > > Christi > ------------------------------------------------------------------------- This list (NEARC-L) is an unmoderated discussion list for all NEARC Users.
