Can you share on Cartotalk how to get a Geotif from Wikimapia? It will be interesting to somehow use this data even as an image in GIS.
Actually I download the cache to a specific folder and find the specific script by which all the tiles are stitched at the webpage with coordinate. Then I have a custom Program which is able to read that cache in read only mode and also be able to export the image to geotif format. It is just a run-time stitching and exporting program.
If you need any geotif image you can mail me (I think you have my mail ID).
