Hi,
I wonder if ogr2ogr can translate/shift vector data within the same
coordinate system. In Postgis I would use ST_Translate(geometry, float8,
float8, float8) to solve my problem.
I have data that is in the swiss coordinate system (metric, scale 1:1),
but not correctly georeferenced. All vector data should be translated
according to a given x/y offset. The output should be again in the swiss
coordinate system.
I looked up the documentation of ogr2ogr at
http://www.gdal.org/ogr/ogr2ogr.html but couldn't find a way to do what I
want.
Thanks for any hint on how to do this with ogr, if it is possible at all.
Andreas,
It should be possible to specify a -s_srs and -t_srs that match the
actual coordinate system, except using a different false easting/northing
for the source srs. This would result in an offset in x and y similar to
the difference in false easting/northing.
You can also use the vec_tr.py sample script to apply particular
transformation to all geometries in a vector layer:

Best regards,
