HI, The question of NODATA processing command is not completelly clear afaik. Infact I found a patch from warmerdam:
https://trac.osgeo.org/mapserver/ticket/2404 Where it speak explicitly of a PROCESSING "NODATA" setting. >I would note that OFFSITE is still supported, and the usual PROCESSING >"NODATA=OFF" >mechanism can be used to disable using GDAL level nodata.
