Dear List,
I have several ASTER GDEM (originally Latlong) images that I want to reinterpolate from 30 to 10 m res. I also need to patch these images. I am not sure whether:
-
I should patch them in Latlong using r.series, reproject into UTM and interpolate them using r.resamp.rst or
-
reproject images individually into UTM, interpolate individually using r.resamp.rst and then patch them using r.series.
So far, I tried the second option. After cubic reprojection and interpolation to 10m the tiles have little borders of NULL areas when I display them together. They don’t go away when patched.
I will appreciate any advice
Thanks.
