[gdal-dev] Linux - bash script - Sentinel 1 processing - dark images

[Andreas Oxenstierna]

I assume the main issue is that Sentinel-1 is radar data in different polarisations - which is not easy to visualise as an ”image" for human eyes

Does anybody have some hints for me how to improve the exposure/contrast of the images?

This doesn't help directly with constructing any command lines you might use, but I found the "Gentle Introduction to GDAL" series by Robert Simmon very helpful in determining what to do.

Here's Part 5, Saturation and Sharpness:

In my memory I have a similarly written article on gdal colour balancing that did have some command line examples but I can't relocate it at the moment. It annoys me that I can't reference it so I'll keep looking. ;-)

cheers,
