[gdal-dev] Combine tiles

[Jorge Arévalo]

Hello,

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"?

Thanks in advance, and best regards
