How to build a tomtom like gps on labview from scratch

[Dawuudie]

Hi all,

Just a bit stuck at the creation of a tomtom like gps, if anyone could help me out that would be great.

Perhaps give me hints and tips and a little bit of codes

Thanx

I think you're not the only one who'd be stuck at that.

I reckon if you don't have much LV experience, this is going to be a VERY hard project.

I mean, assuming you could interface with a GPS and get local positions, mapping this and judging trajectories is not too easy (data is proprietary most of the time I think).

Then you need to have an algorithm to work out the best route given a start and stop position using the map data you have.  This is quite a task.

I may be overshooting the target a bit here, but are you sure you really want a "tomtom like gps" software in LV?

Could it be that you only need a position indicator?  Do you need any route-planning at all?

lol What i really should have said is, improve on my attached GPS(PC1 Nav System v6000.vi), but with this i want to set the destination and the positions the car has to follow, and make the map 3D like so that it kind of looks like a tomtom. I want to make a pointer so that it goes towards the destination and the positions set for the car in such a way that the pointer (arrow) moves along with the map like a real GPS does.

If i am not making sense please get back to me so that i can elaborate on it.

Thnx

more vis attached ...

some more vis and the map.

Something that I have always wanted to do, but never had to the time to do was create a set of VI's to plug into Google Maps.  Google provides an API that you could wrap with VI's and perhaps a small library and then embed the google map onto your front panel.  The great thing about the google maps is that you can give it your current location and your destination and it will handle the details of the route and the display.  All you need to do is integrate it into a few VIs and perhaps add some logic to detect when a turn is ahead based on the directions that google returns.

Here's a link to start with http://www.google.com/apis/maps/

Please let us know if you are able to get it to work.  I would love to see something like this make it into LabVIEW some day.

I guess the down side of my approach is that it requires to have an internet connection I think.  Unless you can just download all of the maps onto your computer first.

josh thanks for the suggestion but unfortunately i am not allowed to use any plugins or such, if you have a look at the vis i sent above may be you'll  understand what i am trying to do (sorry for being a bit vague :s).

Cheers guys

I assume that this is for the Urban Challenge.  I have some VI's leftover from the Grand Challenge that I could send you. You might be able to modify them to do what you want.  No 3D, though.  I have some VI's that plot(graph) a course from a waypoint file, and a bunch of GPS navigation VI's.

Brian if you could please send them to me that would be great.

thnx
