yes, and the r.proj -p and -g flags (or g.region rast=inputmap &&
v.in.region inputmap_box;; v.proj) tell you approx. what it should
be set to, although you should probably check + fix the output
region resolution by hand before the final r.proj run. also note
that if there is much array rotation going on you might make the
resolution a tad bit finer to preserve fidelity. (for simple
units changing there should be none though)
