Just a suggestion: for GeoJson's linear rings in polygons, remove the last vertex

[okrische]

Hello,

thanks for the script.

While debugging my code, i came to see this in the spec:

"Paths are closed automatically; do not repeat the first vertex of the path as the last vertex."

See:

https://developers.google.com/maps/documentation/javascript/reference#PolygonOptions

The linear rings in polygons in GeoJson have this extra vertex. So it could be removed (go up to length-1), when copying/transforming, like your script does.

                        for (var k = 0; k < geojsonGeometry.coordinates[i][j].length; k++){
                            // the ring: array of coordinates, where first/last coordinate/vertex/point match
                            var ll = new google.maps.LatLng(geojsonGeometry.coordinates[i][j][k][1], geojsonGeometry.coordinates[i][j][k][0]);
                            bounds.extend(ll);
                            path.push(ll);
                        }

Thats all :)
