"InSAR Principles: Guidelines for SAR Interferometry Processing and Interpretation" by Dr. #surveyor #geomatics #lidar #radar #digitaltwin Īll of these books can be found and downloaded for free online.ġ. And the amazing "water-penetrating green light" that can measure seafloor depth and river bed elevation.The near-infrared emissions for topographic and structural imaging.□ LiDAR can see through water! This is probably weird and you want to know how. Today, LiDAR is the best remote sensing method for accurate topographic surveys, anywhere in the world. This is amazing in a lot of ways because you now don't need to clear 100s of hectares of land to access the bare earth. □ LiDAR laser pulses can actually penetrate forest canopy, vegetation and undergrowth. I promised to let you in on some LiDAR secrets and here they are □ Structural modelling for digital twin creation So what are the unique applications of LiDAR Mapping? □A Computer system that controls and integrates all the processes □An Inertial Measurement Unit (IMU) that measures the continuous orientation of the sensor/carrier unit, and □A sensor unit that emits pulses and detects back-scatters □ By a walking dude/babe □♂️□♀️ (both indoor and outdoor) Hence its name "light detection and ranging". It emits millions of uniquely identifiable pulse to a target and measures the return time of the signal back to the sensor. It operates in the Ultraviolet, visible and infrared regions of the electromagnetic spectrum. LiDAR is a remote sensing technology that deploys laser pulses to measure elevations of ground, infrastructures and forests But Radar uses radio pulse and Lidar uses laser pulse. Radar and Lidar sound alike and they behave similarly. Stay with me till the end and I will let you in on something you never really heard-of about the #technology In my last post, I introduced the amazing capabilities of Radar remote sensing and I plan to do a little justice to LiDAR too.
