The two maps are showing the same data. d.rast scales each raster to (min,max) of the colorbar, which is why the tiles appear misaligned. The data is unchanged.
Ken, And because each individual tile has diffeent minimum and maximum elevations they don't make a smooth surface while the patched map does. Now I understand.
I don't see how anyone can answer that without knowing the specifics of your project and goals.
To describe geomorphic characteristics of the basin and how they affect channel hydraulics, sediment transport to the lower reaches, and fish distributions, all to a non-technical audience of decision-makers.
I'd patch than resample to avoid possible edge effects, if your resample isn't perfectly aligned with each sub-raster.
This is what I thought made more sense. Your confirmation is much appreciated. Regards, Rich _______________________________________________ grass-user mailing list grass-user@lists.osgeo.org https://lists.osgeo.org/mailman/listinfo/grass-user
