Hi Norman,

gdalwarp -s_srs WGS84 -t_srs EPSG:32618 32V.tif 32V_warped.tif

That turns the image all black (no height values)...

You left the units=m  out of your proj4 string

I also tried

gdalwarp -s_srs WGS84 -t_srs "+proj=utm +zone=32 +ellps=WGS84 +datum=WGS84 +units=m +no_defs" 32V.tif 32V_warped.tif

following the links you posted, and it also turns the image (32V_warped.tif) all black. Same result, so I guess both are equivalent, but not what I had in mind...

Anyways, I've sent the image to Glenn to see what he can find out.

Thanks,

J-S
