Hi Wolfgang, is gdalwarp/ogr2ogr -t_srs "+proj=tmerc +lat_0=0 +lon_0=9 +k=1.000000 +x_0=3500000 +y_0=0 +ellps=bessel +units=m +nadgrids=./HeTa2010.gsb +wktext" - s_srs "+proj=utm +zone=32 +ellps=GRS80 +datum=WGS84 +units=m" ... not working for you?
The default EPSG:25832 can also be written as "+proj=tmerc +lat_0=0 +lon_0=9 +k=0.9996 +x_0=500000 +y_0=0 +ellps=WGS84 +units=m +wktext" Gr Ralf Am Montag 13 Dezember 2010, 12:07:51 schrieb Wolfgang Lahr: > Hello list, > > I am using GDAL/OGR to transform raster and vector data from German > Gauss-Krueger (DHDN) to ETRS/UTM like so: > > gdalwarp/ogr2ogr -s_srs "+proj=tmerc +lat_0=0 +lon_0=9 +k=1.000000 > +x_0=3500000 +y_0=0 +ellps=bessel +units=m +nadgrids=./HeTa2010.gsb > +wktext" -t_srs "+proj=utm +zone=32 +ellps=GRS80 +datum=WGS84 +units=m" > ... > > This works very well (Kudos to Frank and co-developers!!). > > Now, the question came up, how to do it just the other way round, ie from > ETRS/UTM to Gauss-Krueger (DHDN) using the same grid. > > Any hints? > > Regards and thanks > > Wolfgang > > _______________________________________________ > gdal-dev mailing list > [email protected] > http://lists.osgeo.org/mailman/listinfo/gdal-dev _______________________________________________ gdal-dev mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/gdal-dev
