[gdal-dev] gdal 3.1.2: Unknown resampling method: 13.

[Even Rouault]

Martin,

I'm even surprised gdalconst.GRA_Sum was valid in GDAL 3.1.2, as it was 
added (in the Python bindings) only in 3.3.0 per 
https://github.com/OSGeo/gdal/pull/4604

But there were other issues that prevented it to work, which will be 
fixed per https://github.com/OSGeo/gdal/pull/4604

You can workaround by using command line style:

gdal.Warp(output_path, file, options='-t_srs EPSG:3035 -r sum -tr 1000 
1000')
