I've executed gdal2tiles against 2 raster coverages:
- One big raster coverage, composed by several TIFF files. Example of tile: http://dl.dropbox.com/u/6599273/319.png
- One single TIFF file, geographically placed inside the coverage above, but that wasn't procesed in the previous step. Example of tile: http://dl.dropbox.com/u/6599273/319_bis.png
So, I first executed gdal2tiles against a "puzzle" of TIFF files, with a missing piece, and then I executed gdal2tiles against that single missing piece. I want to merge both tiles set. Zoom levels were 4-14, only Google Maps output. Only levels 4-12 have the problem (tiles with the same coords).
Is there any way of merging tiles or should I execute gdal2tiles against the whole "puzzle"?
