Geodesy and Cartography
Most people know the exact shape of the continents without ever setting their foot there. This would have been impossible without geodesy and cartography.
Geodesy surveys, measures and depicts the surface of the Earth while the results are used in cartography, the practice of creating maps and globes. Both sciences have a lot to do also with contemporary inventions such as the GPS and the detailed geographic maps on the Internet. Geodesy and cartography providers offer engineering geology studies and map-making services, among others.
