Description

Tile Map Service Specification http://wiki.osgeo.org/wiki/Tile_Map_Service_Specification describes an image tiling system that is very similar to system used by Google Maps. If TMS tiles are created to WGS 84 / Pseudo-Mercator projection (EPSG:3857, also known as Google Mercator, EPSG:900913) the tiles themselves have the same scale and geographical extents as the Google style tiles. However, the tile naming schema is different.

It is easy to create TMS tiles from any image source supported by GDAL by using gdal2tiles utility (http://gdal.org) or Maptiler software (http://maptiler.org). It would be nice if also TMS tiles could be utilised with Potlatch.

I just came across this issue having created a set of tiles using Maptiler and wondering why the tile numbers were different than existing Mapnik tiles.

Perhaps if the first tile comes back as a 404, Potlatch should then check for that same tile using the TMS naming scheme, so the user won't need to know which type of scheme is being used. In small areas, that should work, but perhaps in larger areas it would cause issues where tile names overlap between the two schemes.
