[gdal-dev] gdalwarp merge problem

[Steve.Toutant at inspq.qc.ca]

Hi,
Still trying to merge images...
I need to merge several images. As an example The image EstMtl.tif must be 
over the image EstGa.tif.

Here is the command
gdalwarp -srcnodata -3.4028234663852886e+038 -dstnodata 0 -of "GTiff" -te 
-931841.246 126213 241462 805816 -tr 30.0 30.0 EstGa.tif icu.tif
gdalwarp -srcnodata -3.4028234663852886e+038 -dstnodata 0 EstMtl.tif 
icu.tif

I think the pixels with novalue of the overlay image are hiding the pixels 
with value of the image under.
Is there a way to avoid this?

Thanks
Steve
