There are 10 Geo locations(longitude&latitude),Markers should be pointed based on the distance between my current location to the first nearest Geo location, From that Geo location to the next nearby location and vise versa.For this particular scenario will any Google map API support or shall we need write own algorithm. If any please let me know.
Thanks in Advance
