Hi,
I am trying to use gdal2tiles with a set of geotiff and I get the
following error
ERROR 6: EPSG PCS/GCS code 900913 not found in EPSG support files. Is this
a valid
EPSG coordinate system?
ERROR 6: No translation for an empty SRS to PROJ.4 format is known.
I have already transformed to projection EPSG:3857, here is the gdalinfo
output for one of the files
the command generates the tiles, but as the images appear a bit shifted I
wonder if it somewhat misinterpreted the projection.
Instead of reprojecting to EPSG:900913 (which will place the points on
the same spot on the globe), try to assign the projection with -a_srs.
This will effectively shift the points.
If the shift goes in the wrong direction, try EPSG:3395. This is the
projection on a ellipsoid rather than a sphere.
HTH,
André Joost
