Hi,

Any ideas? if you use the +nadgrids parameter you must also include also the +wktext parameter example: +proj=tmerc +lat_0=39.66666666666666 +lon_0=-8.131906111111112 +k=1 +x_0=200000 +y_0=300000 +ellps=intl +units=m +no_defs +nadgrids=ptLX_e89.gsb +wktext also, if you are reprojecting to a projected crs, the target crs must include the +towgs84 parameter example: +proj=tmerc +lat_0=39.6682583333474 +lon_0=-8.133108333465099 +k=1 +x_0=0 +y_0=0 +ellps=GRS80 +units=m +no_defs +towgs84=0,0,0 The annoying thing is that every tool that allows reproject vectors (example "save as...") does only let choose the target crs, so you first have to save the vector in what need to be your source crs. On the other hand the warp tool in the "raster" menu let the user choose the source crs, so the transformation can be done in just one step. cheers -- Giovanni -- _______________________________________________ Qgis-user mailing list Qgis-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-user
