I'm working on a disability-vehicle and like to have a navigation system for it.
Like to try and program it myself and when looking for some free map data, I found a site called OpenStreetMaps.
https://www.openstreetmap.orghttps://en.wikipedia.org/wiki/OpenStreetMaphttps://wiki.openstreetmap.org/wiki/DevelopIt looks very promising, it is open source, the data is updated every day and free to download.
Map data can be downloaded here:
https://download.geofabrik.deYou can extract the 2d road data and a lot more from the map data, such as POI's, street names, addresses, traffic stuff, you name it.
My idea is to extract the data I need and draw the graphics in realtime to the on board computer screen.
I'm a total noob in this field but, would like to give it a try.
Have to do a lot more research, such as algorithms to find the way from A to B etc.
Have some of you experience in creating navigation software?
Maybe we can share some useful information?
