[maemo-developers] Maemo-mapper vector data backend follow-up

[From: pierre.amadio at laposte.net]

Hola !

I have been looking at pyrender and did try recently to have a on the
fly vector map rendering in python. It was so slow i decided to use pre
made tiles instead.

I also used most part of pyroute to try to make off line route
calculation:

It works but it eats too much memory.

Right now, i download data from osm, feed a sqlite database, and then
generate pickled python object that can be loaded faster than having to
recompute the graph from scratch.

I'm currently thinking about rewriting all graph related code in C, just
to see how much ram would it save.

I also dont know how one could represent big enough a route to connect 2
foreign city (but, as i do not own a car, this is only a theoretical
problem :-) )
