[GRASS-user] Invalid region and coordinates when trying to reproject.

>    Projection: x,y

It is impossible to reproject from a simple XY location to a
projected location, or vice versa. Simple XY is just like graph
paper, with no Earth-based geo-* part to it. It is most commonly
used for imagery where x,y are measured in pixels, and manual geo-
referencing must be performed, not a reprojection between known
coord systems.

Start over from the beginning, creating a new lat/lon location and
importing your data into it. (assuming that's what the source
data's native coordinates are in)


sorry for introducing the nasty hack which suggested using xy,
