Tools I've used to create OSGB/BNG maps for TB:
Googleak, to produce an Ozi map.
Ozi Map Merge ( http://www.oziexplorer3.com/mapmerge/mapmerge.html ) to convert WGS84/Mercator to OSGB36/BNG and trim to rectangle.
DeMapper ( http://www.terraperfecta.com/demapper.php ) to convert Map Merge's .ozfx3 file to .png
Edit the map file, changing .ozfx3 to .png
TBCutter to create map tiles
Then a script to create tar and tmi files and pack it all into an atlas.
I found it too much work to convert all levels, so I only created an OSGB/BNG map at the top level, with all lower levels in the original WGS/Mercator. If I need the OSGB/BNG coordinates, I zoom to the top level (although I'm not sure if TB then clicks to the nearest pixel, thus losing accuracy).
Hope this helps more than it confuses  |
Hi,
Do you have an example map I could download from somewhere. It sounds like a lot of work so I'd like to ensure it works OK and does what I expect before I install all the apps & start work on it.
Many thanks

The attached zip file contains an 8 level map of most of the UK in OSGB36/BNG format, and a 10 level map of the south-east of England in WGS84/Mercator format, to demonstrate the atlas function.
The .map files are duplicated in the atlas and the tarred maps. I'm sure this is unnecessary, but I've not had the time to check which I should remove.

| Thanks Cactus, once I'd added the 'coords' field it worked fine.
