hi Roland, ArcGIS 9.3 doesn't include the towgs-paramater in the prj-file.
maybe the original definition of a prj-file doesn't include the towgs-parameter, but gdal/ogr needs this information for a correct gdal-warp. I know from the ESRI-side that you have to define this parameter manually for a correct on-the-fly-reprojection, the same for GRASS, because there are not unique towgs-parameter in the epsg-db. it depends from the purpose of the data. best regards Helli >Message: 7 >Date: Tue, 24 Mar 2009 12:31:35 +0100 >From: Roland Kaiser <[email protected]> >Subject: Re: [Fwd: Re: [Qgis-user] Projection not recognised > EPSG:31259] >To: [email protected] >Message-ID: <[email protected]> >Content-Type: text/plain; charset=US-ASCII; delsp=yes; format=flowed > >Werner- > >prj files generated by ERSI products generally lack TOWGS parameters >(see EPSG:1618, CoordinateTransformation, http://www.epsg-registry.org). >Maybe this is solved in ARCGIS 9.3. -- .... . .__.. .__.. .. helmut kudrnovsky mail: [email protected] internet: www.alectoria.at www.myricaria.org ____________________________________________________________________ Psssst!
