I installed it on my linux box at work and it seems to work as well as the windows version. It would do for navigation in a pinch but getting directions from one address to another works for some addresses and not for others. It would definitely be a cool add-on to a real nav app especially using the $20 version that can read from a GPS. Depending on where you live it would be pretty much useless unless you like animated flyovers of blurry 1km resolution photos
the real thing is OpenStreetMap - it's gonna take a while to collect the data (except for the U.S, where the TIGER-import is running at about 1.000.000Nodes/day) but in the end it's the most viable solution for linux navigation.
right now on the software end gpsdrive is probably the best thing available. if you're using the CVS version you can import OpenStreetMap data.
I'm myself an OSM-addict, and mapping is a lot of fun + in the end (which is some years from now) data will probably be more exact/timely than commercial solutions.
i'd find it real cool, if in SW2 you could choose your nav.app of choice and have it switch to it (so everybody get's his preferred app)
Google Earth is also one of my possible choices for navigation. Works flawlessly on my Debian Etch desktop. I am almost sure, you cannot use it for address to address planning, also there is not any street names.
But Google have some other project - Google Maps (completely online) with street names even of my little town at the edge of the world (be sure not to fall off ) in Eastern Europe. There is also a possibility to overlay sat image and navigation maps. And there comes a problem - they are not alligned, an error of approximately 50-70 meters. Not good in a city.
Another problem there is as it is online service you have to manually cache all maps and reuse them somehow.
And last but not least - legal stuff. As I understand - you may use this service, but are not allowed to change the maps or distribute. So, not good for an Open source project I am searching for. But maybe somebody have tried to do something with it. Could be good as it is global, not only US or Western Europe.
I have used GPS before. The problem is downloading the maps before going on a trip. Some times a detour is made and you can't find your self on a map. If your in the middle of nowhere this isn't any use. A wifi connection or cell modem could come in handy in these situations.
Would any one be interested in a script that would download maps for GPS drive when at an open wireless access point?
My thoughts were to have a bash script to download the maps for the current location and other tiles around the area . I might consider adding different zoom level maps too so there will at least be some soft of map.
Let me know by PM or by replying to thread if your interested, my room mate is a GIS major and also uses GPS Drive so I'm sure he'd help with the script.
If you are able to download maps of current position, it would be screamingly awesome indeed! But, if it is done being underway, bad thing is to be dependent on internet connection, and also waiting for download to complete - could look laggy (I mean if I use my super jet ) On the other hand - if you do all the hard work before driving off (and it could be done by the first one of us for every area) you are well prepared with a full func system.
