Hi,
to briefly answer your question, for the methods bilinear, cubic,
cubicspline and lanczos who have nominal kernel radius of respective
values 1, 2, 2 and 3 (and thus a diameter double that size), the radius
is extended by a factor source_size / dest_size to take into account the
downsampl
Hi,
I would like to know if gdalwarp does any "average" regriding when the
source grid is denser than the target grid regardless of the chosen method
for the interpolation. And if there is any document where I can follow
exactly the calculations. I tried to follow the code on github but it is
pret
I think only one alpha band is supported?

I can view this file in OpenEV with no problem
I call
gdalwarp -t "WGS84"

Yes, gdalwarp will use the srs from the file if one is not specified,
providing it is valid.

If I do not provide a source spatial reference to gdalwarp will the
information in the geotiff be used instead? ie. gdalwarp -t_srs
'EPSG:4326' input.tif output.tif?
I do not have a real example because I do not have the file I am working
with on this computer. But an example gdalinfo would be:
