In #700 (comment) opening the file generates the GDAL error that the latitude grid is not evenly spaced. Looking at the raw latitude values that is indeed the case:
The largest difference between the latitude spacing in meters thus works out to be about:
That is about half the ensemble accuracy of the WGS 84 datum that this data is based upon, and with a cell separation of
20000 / 256 = 78.125 km
it seems more of a spurious rounding error rather than an irregular spacing.This is no doubt an issue buried deep in GDAL, but shouldn't the spacing assessment of geodetic coordinates be informed by - at the very least - datum (or ellipsoid) properties?
