[gdal-dev] Specifying output format gives wrong result

2019-09-02 Thread Schmitz, Uwe
Folks, I try to filter a dem (456664_40m.tif) with the help of a .vrt (456664gf.vrt) to get 456664gf.tif. The result is incorrect. It looks like it's slightly pushed together vertically in the middle of the dataset. Please look at 456664gf.tif, compare it to the original 456664_40m.tif and you

Carsten, are you shure that the grid is used during transformation? I know nothing about the C# package, but in my own tests the “not-found” case was often the cause for wrong results. So I tend to almost always use an absolute path to the grid file. Due to historical reasons gdal silently

Frank, So if I conclude: ESRI and GDAL have different WKT formats. It is not possible to write GeoTIFF files which are fully ESRI *and* GDAL compatible. Uwe, I do not agree with this conclusion! However, it is difficult to produce a GeoTIFF file that will exactly preserve and

Hi all, some of our customers are complaining that ESRI products, eg. ArcMap, can't recognize the spatialreference system of GeoTIFF files written with gdal_translate. First I must admit that I don't have ArcMap at hand and can't test intensly. But I verified the statement with a colleagues

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=50 parameter on the command line. Regards Uwe
