Hi Andrea,
thanks for your answer. With resampled I meant the resolution of the
output image. As you can see in my exaple images, the output image has a
(optically) lower resolution than the input one. But that's just
optically because if I run gdalinfo on both of the images it tells me
that they have the same pixel sizes. Anyway you really helped me out
with your hint about the DownloadProcess module which is exactly what I
was looking for.
With this module and with the GetFullCoverage Process I'm able to reach
my goal getting the image data as I uploaded it to Geoserver! Thank you
so much!
Cheers
Alexander
