[GRASSLIST:1058] ellipsoid

Hi,

I need to define a location using a county-wide version of LCC given ellipsoid semi-major/minor axes. I appended the available ellipsoid information to \gdal\ellipsoid.csv, but it did not show up as an option when I listed the available ellipsoids. Do other files need to be edited (\gdal\gdal_datum.csv) ?

Using Cygwin\Grass6.0...

Thanks.

Martin,

you could try to add it instead to
lib/gis/ellipse.table

Modifying the csv files is probably much more complex and should be done
in GDAL (where
we get these files from).
