My 10 cents:
Each contestant or any one else for that matter can make a base map consisting of less than 100 polygons, these are not rated but only 2-3 are selected based on how well they can be expanded.
The contestants would only be shown screenshots of 2D and various 3D paved views before the competition starts, so people can decide whether or not they can work with the base map, without actually being able to work on it. You can choose any of the selected base maps you wish to expand on, as long as it isn't your own map.
Maps are than made available to contestants to download when the competition begins. As for a time limit I think 2-5 days would be quite fun, slaving away into the late hours of the night trying to get it completed. This may not be enough time to test the map though, but a "48 Hour map contest" does have a nice ring to it. This would need a lot of people to sign up to for optimal fun.
