I would love to be able to see UK Ordnance Survey Landranger maps in Maemo Mapper.
These maps look like:
http://www.streetmap.co.uk/streetmap...246500&A=Y&Z=3
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.

I'm having trouble with Download in Manage Repositories: it just hangs for ages and then errors. n800, mapper 2.3.1-os2008
I've discovered that this is because it is attempting to download from port 8080 on the remote server(s), i.e. the "webcache" port. This doesn't get through my firewall. Is there any reason why it doesn't use port 80?
Interestingly, when I try to view http:gnuite.com in my Firefox browser on my PC, it redirects to http:gnuite.com:8080, so that also fails.

After closer investigation, the streetmaps images are too far removed from the google maps images 
however, I've been reading about Microsoft MapCruncher - it's a tool for building custom map tiles for MS Virtual Earth, and by inference, Google Maps. So I'm going to try scanning an OS map, making tiles, and creating a site to host the images. Will let you know how it goes.
See http://www.bdcc.co.uk/GoogleCrunch/Crunch.htm for more info

So I scanned in an OS map, used mapcruncher to plot the coordinates, and put the outputted files on my local web server. Created a new repository, using the URL format http://www.myserver.com/maps/tiles/%0s.png - and bob's your auntie, it works.
I rendered from mapcruncher with a max zoom of 16 - which gave a good image - this equates to a zoom of 4 in maemo mapper. Only real problem may be the amount of data. I did about 1/3 of the Snowdonia 1:25k map, and this gave 350mb of images. Not a problem for me as I have a web server at home, but might be an issue for some.

Hi everyone,
This is my first post here... though I have been reading this forum for a very long. Recently I have been trying to integrate maps from www.mapmyindia.com into MM. I looked at the repositories and found that they are very similar to googlemaps.
http://map1.mapmyindia.com/mapFiles/....5&y=5425&z=13
I could find 2 differences. First difference is that the zoom value (z) increases as one zooms into maps, where as it decreases for other repositories including googlemaps. Other difference is that the coordinates are divided by 10 compared to coordinates in google maps. I think it should not be too difficult to integrate these maps, any pointers would be very helpful.
