Scott,
Since a key aspect of COGs is efficient network access, shouldn’t this file not be considered a COG?
The row-major order (that is tiles are sorted from top-to-bottom, left-to-right) used by the GDAL COG driver is one of the many possible ways of having spatial contiguity being omewhat reflected in a file linear organization. But someone could also possibly use other ordering techniques, like Hilbert curves or other space-filling curves (https://en.wikipedia.org/wiki/Space-filling_curve), to also achieve that purpose. Hence COG hasn't standardized on that. You could possibly open an issue related to that at https://github.com/opengeospatial/CloudOptimizedGeoTIFF/issues
Even -- http://www.spatialys.com My software is free, but my time generally not. Butcher of all kinds of standards, open or closed formats. At the end, this is just about bytes. _______________________________________________ gdal-dev mailing list gdal-dev@lists.osgeo.org https://lists.osgeo.org/mailman/listinfo/gdal-dev
