Technology has no doubt, transformed the face of our planet, and continues to do so. Besides creating revolutionary marvels that change Earth’s landscape, we’ve also been harnessing technology to unveil secrets of science and life that were lost over the years. Remote Sensing is used to retrieve information about objects and areas from a distance, using sensors mounted on satellites or aircrafts. It uses the natural energy reflected or emitted from the surfaces to map their layouts and other intricate details.<\/p>\n\n\n\n
LiDAR or Light Detection and Ranging <\/em>is a remote sensing method used to check the surface of Earth and encompasses data collection from air using lasers and sensors mounted on an aircraft. The principle behind LiDAR is how the light pulses generated by laser sources combine with other data recorded by the airborne system and generate accurate, three-dimensional information about the shape of the target surface and its characteristics. It computes the distance between the various discrete points on the target surface and the LiDAR system as a function of speed of light and time of flight. By rapid succession of this calculation and basic physics, the instrument builds up a complex ‘map’ of the surface being measured.<\/p>\n\n\n\nWhat Fuels Landscaping Using LiDAR ?<\/strong><\/h2>\n\n\n
