This application is also available with Large map.
The OpenStreetMap map type has been added to the Google Maps map types. It has been embedded as a layer within the Google Map. This will in many parts of the world give you map tiles with more details than the default Google Maps tiles.
The feature 'polygon with hole' ('donut') is built-in in V3. Choose Polygon draw mode and follow the instructions. All overlays have style options. There are some custom markers (icons) available for Marker and Direction.
I have posted an example here: Enable editing in V3 And this method is used here in this application to enable editing.
And for editing - if you have a kml file uploaded on a server, and you want to edit its coordinates,
you may use my edit tool Edit tool for Google maps polyline and polygon
You will need a PC or laptop with a large amount of computer memory if your kml file has 1000 coordinate pairs or more.
If a coastline is part of the shape you want to create, you may use templates and build on them
Build Google maps polylines and polygons from templates
Load your kml file with the php function simplexml_load_file(kmlfile) if you want to handle individual shapes in your kml file Dynamic Google Maps API V3
