[Proj] Can I convert the ellipsoids using Proj?

[Jose Gonçalves]

Cleo

If cartesian geocentric coordinates are the same and you just want to
express them in a different ellipsoid you can do:

cs2cs -f %.9f +a=6378136.30 +rf=298.257 +proj=latlong +towgs84=0,0,0 +to
+a=6378137 +rf=298.25722356 +proj=latlong +towgs84=0,0,0

If there are shift and rotation you can express them in the +towgs84.

Regards

José
