A lot depends on exactly what format your existing data is in. If it's strictly an overlay of a paper map, without geo coordinates, then you'll probably have to start over or at least come up with some sort of conversion technique. If you have an overlay that is geo referenced and can convert what ever projection you have into World Mercator, then you'll be a lot further along.
You can use the standard vector approach, using GPolygon, but there are a lot of issues with performance from that angle. Using the tile overlays eliminates the performance bottle necks that occur using vectors, but they are fairly complex to setup and serve. If your vectors are georeferenced in World Mercator, they will line up accurately with the Google Maps tiles. -John Coryat http://maps.huge.info http://www.usnaviguide.com --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google Maps API" group.
