They also do not reverse shift when writing. The other drivers may be making similar mistakes. AAIGRID appears to be self-shifting the projection origin when reading but in the wrong direction. GDALMD_AOP_POINT is not a geospatial hint; setting GDALMD_AOP_POINT means only that the original data was scanned in using point rather than area samples. All drivers should strictly place the projection origin at the upper left corner of the upper left pixel, and quietly shift the projection origin by a half-pixel when performing I/O on point data.",defect,closed,normal,1.8.1,GDAL_Raster,unspecified,normal,fixed,projection origin terragen leveller,moellney
