Think of a pulsed laser. It is projected from an aircraft onto a rocky outpost below. It sweeps the rock, recording the waves reverberating from the surface. What follows is a science: the construction of those waves into a topographical map. This is LiDAR and this is why it’s important.
LiDAR stands for light detection and ranging and is a remote sensing method used to analyze the Earth. The example above is an illustration. LiDAR laser instruments, when combined with GPS systems and a scanner, create a detailed map of the world it is targeting, and the uses are vast.
It is often combined with photogrammetry to create measurements between objects. Photogrammetry is the science of measuring distance within photographs. In other words, LiDAR creates the picture of the world, while photogrammetry measures the distance.
What are the applications of LiDAR surveying and photogrammetry? Here are five industries that these technologies are utilized in surprising ways.
