Geodesy is a field of study that deals with the measurement and representation of the Earth, and it all started when a clever human named Eratosthenes discovered that you could measure the circumference of the Earth by looking down a well. Over time,... the field of geodesy has expanded and evolved dramatically, and NASA uses technology like radio telescopes, ground surveys, and satellites to contribute! Learn more about geodesy in this video! (02:25)

Topographic maps display three-dimensional landscapes on two-dimensional surfaces. The concise maps can offer a great deal of spatial information in minimal space. However, it is often difficult for people to interpret the features on a topographic m...ap. This interactive activity adapted from Stephen Reynolds's "Visualizing Topography" Web site offers color-enhanced and three-dimensional visualizations to help interpret two-dimensional topographic maps.
