I'm getting a strange result when I'm generating an hillshade with the gdaldem hillshade command.
Here is my command (see the compute_edges parameter):
/Library/Frameworks/GDAL.framework/Versions/1.10/Programs/gdaldem hillshade -compute_edges -alt 90 -z 8 -s 111120 /Users/jflegendre/Documents/GDAL_PROJECTS/MP/01-DEM_MERGED/out.tiff /Users/jflegendre/Documents/GDAL_PROJECTS/MP/02-HILLSHADED_DEM/hillshaded_dem.tiff
Here is a section of the output raster:
I've also tried to clip the result with a perimeter shapefile, but there still had some black pixels.
I've tried too the nearblack gdal command without effect. The image that you can see in this post is the result of the nearblack command. So I'm stuck actually.
Can someone help me on this?
