[gdal-dev] Using gdalwarp over NCEP - keep pixel resolution

[António Rocha]

Greetings

I'm doing some SRS conversion of GRIB files using gdalwarp (to WGS-UTM) 
but depending on the zone I'm obtaining different Pixel Size. I know I 
can use the -tr parameter but in this case I know the source_resolution 
(1,5 in NCEP) but I don't know to what it corresponds in WGSUTM.
Has anyone has a tip on how to figure this correspondence in order to 
use that value in the Gdalwarp expression?

Thanks

Best regards,
Antonio
