Hi Feras,

Is your GeoTIFF really a 64-bit image? Seems unlikely but if so, why not
write it out as a 16-bit image, if that is an option?

However, it looks like you are tyring to view a Shuttle Radar Topography
Mission digital elevation model: what are the characteristics of the
original SRTM file? 16-bit?
