Once you've found the segment on which the point lies, you just add up the lengths of the previous segments, plus the distance from the last of those vertices to the point.
The hard part is determining which segment the point lies on. I don't know how to go about determining that. -- http://econym.org.uk/gmap The Blackpool Community Church Javascript Team --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google Maps API" group.
