may I ask for your help about how to use cs2cs.
I got some sample data from southern Germany which (probably) comes in
A single sample point would be
GK: 4491957.175 5511210.407
These values were computed by an online tool.
When I try to convert from GK to WGS84, I guess I have to use:
cs2cs +init=/usr/local/share/proj/world:gk4-d +towgs84
the result is
56d30'44.77"E 39d38'19.023"N 0.000
That's far away. Another online example names:
cs2cs +init=epsg:31466 +to +init=epsg:4326
which returns even worse:
32d6'20.91"E 46d39'54.638"N 16.676
I guess what I do is completely wrong. But I do not find the description
yet how to do it properly.
