Geographic boundaries in GRASS raster/vector files

I suspected as much, thank you for confirming it. Now for the translation:

north = max(y)
south = min(y)
west = min(x)
east = max(x)

Correct?

To be precise, it should be:

    north = max(y) + n-s res / 2.0
    south = min(y) - n-s res / 2.0
    west = min(x) - e-w res / 2.0
    east = max(x) + e-w res / 2.0

if you are certain that the data profiles in your
original data were used as boundaries. Otherwise either
your resolution or rows/cols won't match up.
