[gdal-dev] Problem with gdalwarp and resampling_method

[Daniele Romagnoli]

Hi Jan,
There is a simple TYPO in your commands:

-s_src EPSG:25832 -t_src EPSG:31468

you should use:
-s_srs EPSG:25832 -t_srs EPSG:31468

Note the last char for the referencing options, is an "s" instead of a "c".
Then -s_srs instead of -s_src and -t_srs instead of -t_src :)

Hope this helps :)
Daniele
