[gdal-dev] SAGA: problem to convert grid from ETRS 89 / ETRS-LAEA to WGS84 CRS
Dear all, I try to convert a SAGA grid (SAGA), from a ETRS 89 / ETRS-LAEA to WGS84 CRS , but I get the following error message: gdalwarp -s_srs +proj=laea +lat_0=52 +lon_0=10 +x_0=4321000 +y_0=321 +ellps=GRS80 +units=m +no_defs -t_srs +proj=longlat +ellps=WGS84 +datum=WGS84 +no_defs -r near -of SAGA hdr.sdat ./tmp/hdr.sdat Creating output file that is 39901P x 15248L. ERROR 1: Invalid dataset dimensions : -25635 x 15248 Any ideas ? Thanks in advance. -- Clément ___ gdal-dev mailing list gdal-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/gdal-dev

This seems to me like an integer overflow - looking at the GDAL 1.7.2 sources I see, that the WriteHeader() method of sagadataset.cpp is using GInt16 nXSize, GInt16 nYSize Most likely this should be changed to int nXSize, int nYSize Best regards, Volker Am 06.01.2011 10:48, schrieb Clément Tisseuil: Dear all, I try to convert a SAGA grid (SAGA), from a ETRS 89 / ETRS-LAEA to WGS84 CRS , but I get the following error message: gdalwarp -s_srs +proj=laea +lat_0=52 +lon_0=10 +x_0=4321000 +y_0=321 +ellps=GRS80 +units=m +no_defs -t_srs +proj=longlat +ellps=WGS84 +datum=WGS84 +no_defs -r near -of SAGA hdr.sdat ./tmp/hdr.sdat Creating output file that is 39901P x 15248L.
