[gdal-dev] gdal-dev Digest, Vol 208, Issue 15

Thank you very much for your answer, indeed when I add -oo EXTENT_METHOD = MOST_PRECISE_TILE_MATRIX to the gdalinfo command, it now works the same in both cases. But I have one more doubt, what would the correct syntax for Gdal.Open in c # look like? Thanks and regards

Elena,

the difference is likely due to the PROJ version used. I'd assume in the first case to be PROJ < 4.9.3 and in the second PROJ >= 4.9.3

You actually get a better result in the first case. If you add -oo EXTENT_METHOD=MOST_PRECISE_TILE_MATRIX, you should get the best result in any case

I've filed an issue https://github.com/OSGeo/gdal/issues/4461 about that
