Hi Hrvoje, Contrast enhancement is through linear stretching with saturation. Next step I'll work on would be to take into account the clouds. (Which are not much of a problem in Sahel...) Yes, you can compare before and now versions (temporarily). For the old version, add an extra layer with "mali_v0" instead of "mali" in the TMS address. (Most of the images were directly the georeferenced jpeg generated by USGS, available in "GIS ready bundle". The remaining 230 or so had been generated from L1Gst geotiff). Zoom level 19 is not really needed. It is just a default parameter of my tilecache configuration, which also includes other images, sometimes with better resolution. And I still get requests for level 20. :) (And also, not all uses are through JOSM, which can virtually zoom in itself).
