Hi Aaron- You'd need to check whether any line in the polygon intersected any other one. There are various line intersection algorithms on the web, and it may be easier for you to use them after performing fromLatLngToPoint on the vertices of the polyline.
Here's an example function I found for processing that could be adapted: http://snippets.dzone.com/posts/show/2087 There's also a thread in the JS API group which discusses some hacks that could work most of the time: http://groups.google.com/group/Google-Maps-API/browse_frm/thread/9a3908309589832e/5559ada61e38f536 - pamela On Thu, Mar 19, 2009 at 10:48 AM, Aaron Donohue <[email protected]> wrote: > > I have created an application that allows a user to draw a polygon on > a google map.
