Use Google Maps API `<a href="[url removed, login to view]">GPolygon</a>` and `<a href="[url removed, login to view]">GPolyline</a>` to allow a user to create a polygon from scratch, then edit it by dragging points on the polygon. This imitates Google MyMaps draw polygon behavior. It is described at this link:
[url removed, login to view]
With the above methodology as an example, use the functionality of this site as an example:
[url removed, login to view]~lvberkum/
Basically, you can take the above site as an example ([url removed, login to view]~lvberkum/) and replace the existing draw polygon methodology using markers with the MyMaps method described in the first link ([url removed, login to view]
Completed task must be demonstrated on a web page. All source must be provided.
This is a very simple task for someone who knows the Google MAP API
