[gdal-dev] Problems with large ASTER GeoTIFF

[MORREALE Jean Roc]

If you're talking about the EAA EU_DEM then PNG isn't a good solution as 
the whole raster as to be loaded to access a subset of it, a compressed 
TIFF with TILED=YES would be better.

Also, you should not try to scale it down to byte as it would only 255 
values, if I remember well the original data is in ctfloat32 so try to 
scale it down to int32 for a huge size gain.
