[gdal-dev] Infinite loop Netcdf/HDF5 -geoloc when warping (version 2.4.4)

[Menno van Scheers - HUSS]

Hi Even,

First thanks for the speedy  reply.

We have used a couple of different version and packages to test this (So a complete gdal update with the associated libhdf5 and netcdf).
In the project itself (.NET) we used 2 different version from the gdal package https://www.nuget.org/packages/GDAL/ (2.4.4 and 2.43)

For testing on commandline I downloaded the prebuild package from http://www.gisinternals.com/release.php

This was also reproduced on a completely clean machine with no prior GDAL or other dependencies installed.


Best Regards,

Menno Van Scheers

Menno,

did you just update GDAL or GDAL+libnetcdf/libhdf5 ? I can't replicate the error you see with GDAL 2.4 or master, and libhdf5 1.8.16 from Ubuntu 16.04

I've tried on ftp://msgcpp-ogc-realtime.knmi.nl/
SEVIR_OPER_R___MSGCPP__L2__20200305T000000_20200305T001500_0001.nc

By the way the georeferencing of that product is broken (but that's unrelated to the issue you get):

		projection:semi_major_axis = 6356584.f ;
		projection:semi_minor_axis = 6378169.f ;

semi_minor_axis should be <= semi_major_axis, not greater
