问题
I need to create an instance of a Google map that uses markers from an external Google Map. More specifically I need to grab all the markers from the "source map", run some algorithms and filtering and them add them to my newly created Google Map.
I've tried searching both the Google Maps API and forums for clues, but most of them are about getting markers from the current map, and not externally.
Do I need to use the KML source somehow?
Thanks in advance!
