Think you know your way around the world? Why not take the Blue Marble Geo-Challenge. Each month we provide five images captured in Global Mapper showing a city, country, or some other geographic feature. All you have to do is identify the feature, submit your responses, and your name will be entered in a drawing to win a copy of Global Mapper.
