BING MAPS Drawing a zone based on various coordinates -


i have database coordinates of map point, information have draw circle zones in dependency proximity of it, example if have 4 point close 2 miles create zone , i'll draw zone in maps, need know formulas or methods need solve problem, maybe can documentation kind of coordinates algorithm

there couple of different ways this. 1 option group locations based on distance clusters , use coordinates of each point in cluster create convex hull. http://www.codeproject.com/articles/29275/convex-hull

another approach create voronoi diagram create regions. take @ blog post: http://alastaira.wordpress.com/2011/04/25/nearest-neighbours-voronoi-diagrams-and-finding-your-nearest-sql-server-usergroup/
