Hi guys, I have a really tricky problem here and I'm hoping that there is a math guru here who can help. The problem Using Google maps, I need to allow a user to draw a line. This line can be in any direction and basically, I need to determine if the user has drawn the line over a road and if so, how many. Below is an example: The image doesn't seem to be showing so here is the link: View image: map basic With Google Directions service, I am able to get the nearest road the the dropped marker (markers indicated by arrow in image). For a single road, I believe that I can do this with Pythagoras, but for multiple roads by brain starts to boil. If anyone here could help, I'd really appreciate it. I appreciate it is pretty tough so I'm open to all suggestions. Thanks!
