I'd like a Linux program which displays ASCII ArcGrid files (NxM rectangular ASCII data grids which may have either integer or floating point values). There is no practical upper or lower limit to these values.
I would like suggestions of a program which could read in this rectangular grid and display it in colour. The program must also have the capability to rescale the data so that I can isolate ranges of interest, it would be best if the rescaling could be nonlinear. (A nice, intuitive interface for this would be bestest.)
This is somewhat of a GIS application, so answers dependent upon conversion to the GeoTIFF format are acceptable.
Gimp did not work for me, so if you suggest it, you should be very specific about how to get it to display the GeoTIFF format (or a rectangular grid)
