Hi Andreas, I'm Bringing this back to the list, as others here probably have some better thoughts than I do. Googling around, I found this tool which might be useful (?), though I can't tell how it handles overlaps [haven't even downloaded it...]: https://trac.osgeo.org/gdal/wiki/Correlator
Not sure about enblend (can't access the site right now) Depending on how different the images are, you could just try mosaicing and see what it looks like (gdal_merge takes the values of last image added for overlaps). If there's a way to standardize color values based on brightness, or by RGB bands, that might help, either before or after mosaicing. (might depend on if you're dealing with multi-band image, or single band? - it would be fairly easy on multi-band like Landsat) Hope that helps, mike On Wed, Dec 10, 2014 at 9:28 AM, Andreas Neumann <a.neum...@carto.net> wrote: > Hi Michael, > > I have 4 images with approx 30% overlap in each axis (north/east).
