Missing functions in Google Maps API V3
I am upgrading trackyourruns.com from Google Maps API version 2 to version 3. The process has been fairly painless but I have discovered that a few key functions are missing. For example I was using the getLength() method of GPolyLine (PolyLine if V3) to determine a line’s length in meters. Currently, there is no way to do this using version 3 of the Maps API. Fortunately, José Fernando Calcerrada created extendedApi which adds functions to LatLng, Marker, Polyline, Polygon that are missing in V3.
