I have a gps device that does not output very accurate gps positions. How can I round those coordonates so that they will match the street course and not buildings etc ? I want to draw a route on google maps but the line strikes buildings etc. I don't want that i just want a route on the street. Thanks |

What you are searching for is Map Matching. The point is, that you are not "rounding" the coordinates but searching for the nearest point on a street. There is no Google API that offers exactly that, but the Directions API offers a way to calculate a route with given Waypoints. This Question on Stackoverflow describes a way to do that: http://stackoverflow.com/questions/3404499/plotting-a-route-on-google-maps I hope this helps, B. |
