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.
I'll look into creating it one then. I'll have to whip out the ole' GPS and laptop for the time being.
