Where the X= and Y= numbers refer to positions on a rectangular grid for the UK (which can be derived from GPS lat/lon by some messy maths).

Is there a simple way to achieve this directly in Maemo Mapper?

If not, I wrote my own basic GPS application for a Psion handheld computer some years ago for which I fetched a large number of the Ordnance Survey Landranger tiles, each 200x200 pixel tile providing the data for 1km x 1km. Is there a way I could use such tiles, e.g. served by my own private web server from home, with the wonderful Maemo Mapper?

I've tried to find out sufficient detail about the URI format MM uses to fetch tiles, but I've failed to find:
- whether the X,Y co-ords reference the bottom-left, center or some other part of the tile;
- the relationship between zoom factor in MM and scale (i.e. pixels->meters or lat/long displacement)
...am I being daft in failing to see this?

Thanks in advance for any assistance,
Simon.
Do the tiles look the same size as for google etc... If so, it would probably be relatively easy to make a web service to take x/y coordinates and return streetmap images
