Hi all,
Morten Hulden has done much work on r.proj:
"> Item: r.proj
I've done some hacking on r.proj and I now have a patch that
- aborts if the input map is outside current region
- trims the output map to the current region or smaller
- does not allocate more memory than necessary for projecting the
overlapping parts of the input map and output region
- aligns cell edges and centers of the output map exactly to those
of output region
- matches (unless changed explicitly) resolution exactly to that
of output region
- during overlap checks, passes cell centers to PROJ instead of
edges (which are invalid in many projections, causing 'Error in do_proj'
aborts)
- allows projecting azimuthal, conical etc maps even if north is
not upward or east is not rightward (no more 'north must be greater than
south' or 'east must be greater than west' errors)
It is in CVS now.
Thanks, Morten!!
Markus
