Well to be honest, i've never done it before and therefore have no idea where to start.

So probably actually getting the lines and squares drawn on the map is where i need the majority of help at the moment.

Let me just give you a bit more information about the overall object im trying to achieve. I want to create a system for my Virtual Airline that displays a route on that base map as shown above. I am not aware of your aviation knowledge, but planes pass over waypoints in flight, and it is those i want to plot on the map.

Regards,
