Hi, The trial with gdalinfo makes GDAL to try XYZ https://gdal.org/drivers/raster/xyz.html?highlight=xyz. It is not a bad guess at all. Ogrinfo tries CSV and finds the x, y, and val fields. I can’t say anything about the second part.

First, it reported "Ungridded dataset: At line 3, change of Y direction" (as a warning to the registered error-handler) and the returned OGRDataSource* was null. When I tried again, it then claimed that I was trying to open the same file recursively. implying that it had, in fact, opened it, even though it never returned a valid handle, so I wouldn't have been able to close it again even if I'd wanted to. I can reproduce the first part with gdalinfo. This is with GDAL 3.2.2 on Ubuntu 20.04 with GCC 9. I'll poke at the GDAL code myself when I have a bit more time. -- [http://www2.omnisci.com/l/298412/2018-09-18/3sqpg/298412/61753/OmniSci_Email_Header2.png]<http://www.omnisci.com/> Simon Eves Senior Graphics Engineer, Rendering Group 100 Montgomery St (5th Floor), San Francisco, CA 94104, USA Email: simon.e...@omnisci.com<mailto:simon.e...@omnisci.com> | Cell: +1 (415) 902-1996
