It's not as easy as that, polylines are defined by vertex. I'd guess you'd still want to match a polyline if it crossed your point some way from the vertices on either side? Then there's the question of many millimetres of precision? A point is a point, a polyline might pass within 1km or 0.1mm of it, you need to draw a distinction about how close suits your needs. It's probably more desirable to find polylines passing within Xm of your point, than actually dead-bang on it. There are tools to calculate distance from a point to a poly - http://maps.forum.nu/gm_mouse_dist_to_line.html You could use your loop-through-my-polys technique to determine each distance, and select the ones within your chosen range. cheers, Ross K --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google Maps API" group.
