google maps - GoogleMaps Polyline Length in V3

Question

There doesn't seem to be a length funciton for the Polyline in Google Maps anymore in V3.

Has anyone found a workaround for this functionality gap?

Answer 1

<script type="text/javascript"
src="http://maps.google.com/maps/api/js?libraries=geometry&sensor=true"></script>
... var path = poly.getPath(); // or:
var path = polygon.getPath(); 
... = google.maps.geometry.spherical.computeLength(path.getArray())
... = google.maps.geometry.spherical.computeArea(path.getArray())

--> distance for polyline, area for polygon

and between two points: computeDistanceBetween()

Don't forget to specify the geometry library (libraries=geometry)
