[gdal-dev] Create a Google Earth overlay based on Geotiff

[António Rocha]

Hi there
It worked (my problem was that I was using gdal_translate instead of 
gdalwarp to reproject the images to EPSG:4326).

But now I have 1 little question:
When I do the reprojection of the image from my UTM to EPSG:4326 It 
creates a black-NO VALUE area around the image due to projection. In 
order to auxiliate the visualization is it possible to turn this no-data 
into transparent?
