    Question Find all exact locations along a route

    Hi,

    Is it possible to find all the exact locations (lat, long) within 5 metres of each other on a route? i.e. for a 50 metres long route, I am expecting 11 locations (1 start point + 1 end point + 9 points between the start and the end).


    Thanks

    Hi,

    No, but if you describe what you want to acomplish some of us can maybe give some workarounds to fit your needs.

    I think you would need a cunning search algorithm - probably working on a grid. Interpolating and extrapolation. It would be very slow.
    You would find the distance from each trial point to the route segment under consideration. If it is "close enough to zero" then that's a point for your list. It will get very complicated with curved routes/etc.

    Thanks with your help guys.

    I would like to find the difference between the computed route and the
    actual car route (loading a gps sentences retrieved by a car along the
    route). Problem: I think Mappoint doesn't expose all the locations on the computed route.

    Re: Find all exact locations along a route

    Hi,

    Did you ever solve this problem ?

    If not could you please let me have some more details as I think I might have a solution for you, it would require loading the computed route into Mappoint and then running a process to detect the deviation from the route at each GPS location, This could be automated and I have a method to do this but I would need you to send the saved route from Mappoint and a sample of the actual route in GPS Lat and Long in some format that I can work with (excel / CSV / Txt).


    Regards
    Nigel

    Re: Find all exact locations along a route

    I am using Ms Virtual Earth (Bing v6)
    I have geocoding locations of all contacts (Offices) in database. But when I search for a specific route, I just want to mark those offices positions which are in 10 or 20 or 30 etc KM radius of that specific route. Can anybody please help me to figure it out.
