This photo is a result of LIDAR remote sensing and is used to capture very detailed surface images. The purpose is to detect surface change over time. Maps are only relevant when they are up to date which is why this type of remote sensing is so useful. For example, this type of sensing would be useful to see surface change after a volcano because going to physically look could be hazardous. This way changes can be observed accurately and safely. Watch the photo for a few seconds to observe the differences; this photo is also a cartographic animation!
