We don’t know what you are doing.

  • You used Haversine and ‘same problem’. What Haversine algorithm and how did you implement it?

  • to calculate driving distance following a route if you don’t want a straight-line distance between points; try

    1. HOW TO: Use the Navigate control
    2. Use the Google Directions api. Use it with a Google Map API key .
