Description
I have a AIG dataset of Queensland, Australia. In MapWindow, the data looks correct (with the exception of some systematic offset errors near the coast that aren't too serious).
When I run this file through gdaldem -color-relief
, the output is almost correct, but with small regions of 'noise' that results in heights of 18,000ft, or -40,000ft, for example.
I am using the gdaldem from http://www.gisinternals.com/sdk/PackageList.aspx?file=release-1600-x64-gdal-1-11-mapserver-6-4.zip
my command is: gdaldem.exe color-relief "e153s29dem1_0\w001001.adf" "colourTextFile.txt" "deme153s29.png" -of PNG
