So mostly your question is about having support for leading zeros in the tile path? I don't know whether this is supported by Marble yet. I'd just like to point out that the old  Worldwind tile format had leading zeros as well.

Hi all,

maybe one of you can give me a hint how to
solve following task:

For the GIS app i am developing i need to add ESRI mxd maps.
Mxd is a container which adds several vector/raster layers to a map.
With ESRI ArcObjects sdk it is possible to crunch the mxd maps into
map tiles.
These map tiles are similar to osm tiles, the main difference is that
the tiling schema created by the ArcObjects sdk does not match to
tiling schemas used by osm, google or other online maps.

for example:
regardles if you use osm or google or nokia maps,
a map tile located in the same folder:
\zoom folder\longitude index folder\latitude index tile name
are allways describing the same area in geocoordinates.

The ArcObject sdk also creates such folder structure: 
\zoom folder\longitude index folder\latitude index tile name

But regardless if you crunch a worldmap or a city map,
the created zoom folder allways starts with 0 to n.
For example when i crunch a munich city map, the first map tile
showing the whole city is located in: 
.\L0\R0000\c00000000.png
Next level is:
.\L1\R0000\
      \R0001\

Now i was wondering if it is possible to config a dml file the way,
that this folder structure can be used to load the map tiles,

thanks for support,

konrad
