Subject: GRASS is messing up Robinson projection
grass binary for platform: Compiled from Sources
GRASS Version: CVS 2004-7-24
When using an external PROJ 4.4.8, GRASS is shifting the coordinates for the Robinson projection.
Along the equator and the poles there is no shift. But at mid latitudes, everything is shifted approx.
20000m vertically (no x-shift) towards the equator. Moving towards the poles or the equator the
shift decreases. The same happens in the inverse (from Robinson), except that the shift is towards
the poles.
I've checked with the PROJ lib proj command and it does a correct projection and inverse projection.
But with GRASS m.proj2 (in 5.3) and r.proj and v.proj (both 5.3 and 5.7), everything is shifted.
When the previous proj - 4.4.7 - is installed, GRASS projects to and from Robinson just fine.
