LIDAR

http://rst.gsfc.nasa.gov/Sect8/Sect8_8.html

LIDAR (Light Detection And Ranging) uses lasers to map out an area. Lasers are shot out and bounce back from an object and repeated to show the features of the object. LIDAR produces extremely accurate images with lots of detain and can even make 3D images such as the exaple of downtown Kansas City above. LIDAR is good at showing size and distance of objects.
