Lat/lon is still incomplete. The digitizer and i.points assume that
the map or image can be rectified to your geograhic projection using
a linear mapping. This is mostly true for UTM, but it is completely
wrong for lat/lon. There is no method (at present) to digitize maps
into a lat/lon location or register images to a lat/lon coordinate
system either.

|Hello,
|	We are trying to do some digitizing and image registration in a mapset
|	using lat/lon.  We have experience working in UTM but need to do some
|	work in lat/lon.  We first run i.target directing the output to our
|	mapset in lat/lon but the program i.points seems to only accept UTM
|	coordinates.  In fact it will not accept the lat/lon coordinates
|	we type in. 
|	Does anyone have experience with lat/lon mapsets in grass?
