I don't manage to reproduce. Might perhaps depend on the dimensions of the input dataset and/or cache size used That said, it is not inconsistant that some code tries to read blocks on the newly created dataset. Probably that the Create() method should use VSIFTruncateL() to set the file to the full size if filling with zeroes is OK for the format. Otherwise you may need to pad with more appropriate values. That way potential IReadBlock() won't error out. > > > > > -- > View this message in context: > http://osgeo-org.1560.x6.nabble.com/Error-in-GDALWarp-to-NWT-GRD-tp5276136 > p5276137.html Sent from the GDAL - Dev mailing list archive at Nabble.com. > _______________________________________________ > gdal-dev mailing list > [email protected] > http://lists.osgeo.org/mailman/listinfo/gdal-dev -- Spatialys - Geospatial professional services http://www.spatialys.com _______________________________________________ gdal-dev mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/gdal-dev
