I'm attempting to use the minimum operator with gdalwarp v2.1.0 but it always mosaics as if I had selected nearest neighbor.
From the docs:
-r resampling_method: min: minimum resampling, selects the minimum value from all non-NODATA contributing pixels. (GDAL >= 2.0.0)
The command is staightforward:
gdalwarp.exe -r min -srcnodata -9999 -dstnodata -9999 a.tif b.tif ... z.tif output.tif
But it gives me this output:
When what I expect is this (mosaicked through ArcMap with the minimum operator):
This totally looks like a bug to me but I figured I'd ask here first in case I'm missing something.
