[ gpsdrive ] External program interfacing with gpsdrive

[stan]

Still working away at this. A function to search for streets, towns etc. 
should (that can be a very deceptive word :) ) be simple enough to build into 
the poi finder by adding a few extra functions to gpsdrive's database access 
layer, the most important parts are already there.
There are some problems though, the osm data doesn't really have much in the 
way of street numbers, fine if its a short street but not so good for streets 
several miles long.
For now separate entries for country, town and street will work but it could 
really do with a proper search engine.

Routing. In short, its almost impossible with existing osm data, more on why 
here:
http://wiki.openstreetmap.org/index.php/Routing_with_osm_data
Is it just me that has trouble finding anything on that wiki? Anyway, it could 
be possible to do routing by searching for roads that nearly join and assume a 
junction, either in the db or directly in the routing functions but it would 
be slow, inaccurate, require a lot of work and would frequently plot routes 
that expect you to drive through walls. Openstreetmap are trying to deal with 
the issue so it will be possible at some stage.
