Free Drawing Feature
When you draw freely, Javascript function polygon takes the array of coordinates and encodes it. This encoded array GET sends with his request.
GET When a request arrives, another function that controls it receives and decodes it. According to the resulting coordinate sequence, a polygon draws areas and places markers on the map.
For all this point on polygon I researched the problem and Ray Casting I found a solution using the algorithm.
