[gdal-dev] re-gridding to a coarser grid

[Travis Kirstine]

Andreas,

gdalwarp can be used to resample images using the -tr flag or -ts flag.

For example resample 1m image to 10m using cubic resampling and
"target resolution'

gdalwarp -r cubic -tr 10 10 input_1m.tif output_10m.tif

You may have an issue determining the output resolution as I believe
the resolution will be in decimal degrees rather than arc-seconds.

Regards
