google.maps.Polygon.moveTo()

Programmatically move a google.maps.Polygon to a new google.maps.LatLng using Google Maps V3 Built by Bramus! - http://www.bram.us/

About

Since Google Maps v3.11 it's possible to move around a google.maps.Polygon by using the mouse (if the draggable property is set to true). google.maps.Polygon.moveTo() is a Google Maps extension augmenting that functionality by allowing one to programmatically move a google.maps.Polygon on the map without any user/mouse interaction. The script works with both geodesic (polygons that follow the curvature of the earth) and non-geodesic (straight) polygons.

Installation

• Include the scripts js/google.maps.Polygon.getBounds.js and js/google.maps.Polygon.moveTo.js in your HTML page
• Include the Google Maps script with the Google Maps Geometry Library included. You can do this by referencing http://maps.googleapis.com/maps/api/js?v=3.exp&sensor=false&libraries=geometry

How to use

See the example. Basically just call myPolygon.moveTo(new google.maps.LatLng(lat, lng)) to move the Polygon to the new Latitude/Longitude.

Notes / Bugs

• Alas it's not perfect: Rounding errors occur (You can see this best when moving a polygon with geodesic enabled to one location and then moving it back: you'll see that the shape seems to have tilted a bit)
• When using non-geodesic polygons it's recommened to wrap google.maps.Polygon#moveTo() in a setTimeout() with a timing of 200 in order to have google.maps.Map#getProjection() available (it's only available after the map has started rendering)
