try gdalwarp to see how the raster is re-projected there and then compare
the settings in GRASS.

the real strength of GRASS in raster is, that you can change the computional
region of interest to extent and resolution to what fits best for your
analysis. you can change back to resolution and extend to your original
data.
Thanks, Helmut. Working through the r.proj process clarified most of my
confusion.
What remains for me to better understand is the relation of raster regions
and vector regions. I'm working on this.
Best regards,
Rich
