Comments For This Page
Max, it's not possible to close the polygon if its not already closed. If the polygon was closed before it was encoded, then it will appear closed here. Export to KML has been added to the Future Ideas and Features list.

How do you finish the polygon i.e. close the loop from last point plotted to first? Would it be possible to make the created polygon available as a .kml file?
