Welcome and thanks for your interest in Overflown Countries. This web application is the result of a sub-project which is part of the more global one called GMapify. Feel free to explore this website full of maps and geodata. Maybe you could find other interesting stuff ;)
OverflownCountries is a tool for people who want to known which countries they overfly to go from one point on Earth to another following the great circle. This path is more or less the route taken by planes between two airports.
