hi Hamish,

curious - what does that mean? To use ogr2ogr in conjunction with
g.proj -wf is one of my favourites... but is

GRASS 6.4.svn (latlong_tbe_climate):~ > g.proj -wf
GEOGCS["wgs84",DATUM["WGS_1984",SPHEROID["WGS_1984",6378137,298.257223563],
TOWGS84[0.000,0.000,0.000]],PRIMEM["Greenwich",0],UNIT["degree",0.0174532925199433]]

sufficient to work around the indicated '+nadgrids will be ignored' problem?

thanks,
Markus
