Hi all,
I have a shapefile with the following in the prj file:
GEOGCS["GCS_ITRF_2000",DATUM["D_ITRF_2000",SPHEROID["GRS_1980",6378137.0,298.257222101]],PRIMEM["Greenwich",0.0],UNIT["Degree",0.0174532925199433]]
Anyone know how to convert this to a proj4 definition?
Thanks,
-Steve
One option could be to simply convert the shapefile into GMT format.
# -fid 0 keeps the GMT file small
ogr2ogr -f GMT yourfile.gmt yourfile.shp -fid 0
You'll find something like this in the GMT file:
# @Jp"+proj=longlat +ellps=GRS80 +no_defs "
