Brilliant. Thanks, Uwe. I will try that and let you if it works. From: Schmitz, Uwe [via OSGeo.org] [mailto:ml-node+5841399-2004682561-308...@n2.nabble.com] Sent: 16 December 2010 09:44 To: Heng Feng Subject: AW: [gdal-dev] An issue about using GDALWARP to do the NTv2transformation
Heng, as Frank wrote the coordinates you try to transform are far outside the BETA2007.gsb grid. Is it possible that your georefrenced raster fiel lacks the Gauss-Krueger meridian prefix? If so, you can try with a modified "+x_0=500000" parameter on the command line.
