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: http://postimg.org/image/iuj9e8jfj
With Google Directions service, I am able to get the nearest road of 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!
