Roadnav - Open Source GPS Navigation

Digging around a little bit in the world of carputers following our recent post on the Subaru carputer, I came across Roadnav, a cross platform, open source GPS mapping program from Richard Lynch. One thing that makes this project different from many commercial solutions is that it uses free US mapping data from "the US Census Bureau and the USGS." It then renders the maps from that government data. I believe most commercial mapping data is supplied by Navteq, whose trademark you are probably used to seeing at the bottom of Google Maps. Roadnav is a bit rough around the edges, but given the limited number of GPS navigation solutions for the Mac it's certainly worth checking out.

And what about Europe?

For Europe, it can also use the maps from the (still not ready for prime time) Open street map project.

(Besides NavTeq, the other big commercial digital map provider is Tele Atlas.)

It's a start, but even with regular updates, it will most likely be years before this application can come close in functionality to iGuidance or even Microsoft Streets & Trips.

I like the idea of a free mapping program, but the routing totally sucks in this one. To check it out, I use a route between Chicago and Champaign IL, and has me only taking the expressways half the way, and puts me way out of the way.
I think it's a good idea, but will take quite a while before it's close to prime time.

Speaking of which... is there a Mac (Universal) version of MS S&T out?

Glad to see this subject: Anyone know of open source navigation GPS CD that I can drop in our Nissan Quest. To update the disc that plays inside the navigator is very expensive (I can't recall the company?) in the area of $600,
Thanks. BTW love this site.

Is there a mac version of M&S Streets and Trips, period? Seriously, I don't know.

There is also RouteBuddy http://www.routebuddy.com

routebuddy is not free nor is it opensource. With routebuddy you still have to buy the maps you want to use so it is not a nice solution.
I have not seen an osx version of MS S&T of any version.
Also for the person who tried to map between one city to another city that used expressways. If you would have looked under prefs you would have seen a way to give weight to how you wanted to give you directions. You have three choices to do that.
This software is very rough around the edges but I think it is doing a good job so far. I am waiting for my bluetooth gps device to charge up to give it a good testing with that but hey a universal client for win, nix, and osx you cant complain to much. So me a cost effective program that can do this...
