Well I spent a good it of time last night coding the output code to produce files in the right format for TomTom navigator.

Not that it has got anything to do with with the fact that I finished wiring in my GPS unit into my bike.

Anyway, I added the news to the front page but still have a bit more work to do. Apparently TomTom throws a wobbly if you have more than 100 points in one file, so requires you to encode thigns in an optimised b-tree. That's great, but the SDK from TomTom themselves lacks any description as to how they do this.

Nothing like working from scratch to stretch the brain...
