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
