Hi to all,
I am a newbie on this list, I am triyng to project some lat-long points
(international ellipsoid on
rome40 datum)( 12.17183333 43.55000000) to Gauss-Boaga Projection
(tmerc on
+international ellipsoid on rome40). I use:
cs2cs -E +proj=latlong +ellps=intl
++towgs84=-104.1,-49.1,-9.9,0.971,-2.917,0.714,-11.68 +to +proj=tmerc
+lon_0=15
++k=0.9996 +x_0=2520000 +ellps=intl
+towgs84=-104.1,-49.1,-9.9,0.971,-2.917,0.714,-11.68 -v -f %.6f
I have reprojected the values to GB with grass in order to test the
result (the
+result shold be: 2291529.04882672 4825875.89322372 according to
grass)
But I get wrong values, especially on latitude (2205154.728842
5838292.243164)
can someone help??
cheers,
Francesco
