LiDAR got a big boost when the North American Reliability Corporation (NERC) issued its NERC Alert of 2010. It all depends on the resolution of the LiDAR system and the size of the area being mapped. The size of the point clouds are massive and can be in the terabyte ranges. The system produces a high density point cloud from the LiDAR surface reflections. The LiDAR system consists of a laser emitter/receiver, GPS (global positioning system), and some form of inertial navigation system. There are four popular platforms in use today, airborne (aircraft and drones), terrestrial (tripod), mobile (moving vehicles), and handheld. By definition, LiDAR is an active remote sensing and geospatial system. Before getting deeper into LiDAR, this is a good time to look a little closer at the technology itself.īasically, LiDAR technology is rather straightforward. Yet it took decades of hard work and development to accomplish. It’s interesting many consider LiDAR to be one of those overnight technological success stories. The power delivery industry has been a power user of LiDAR technology for several decades, but the use has mainly been with vegetation management and transmission line mapping. North America is expected to dominate the LiDAR market by region because of environment, corridor mapping, meteorology, and urban planning applications. According to a recent report by Markets and Markets about US$1.1 billion was spent on LiDAR in 2020 and they expect to see it reach US$2.8 billion by 2025. When it comes to remote sensing, LiDAR can’t be beat, and the more commonplace it is helps the technology. Seriously, the variety of LiDAR applications are growing at a tremendous rate worldwide. So, expect to see more people chattering about the technical merits of LiDAR technology at a watercooler or coffee shop near you.
It is a trend that will continue growing and encouraging more innovation. Augmented reality (AR) is benefitting from the addition, and you can see some very interesting YouTube demonstrations for anyone interested.Īs more people download these LiDAR apps, the technology is getting into more user hands and user friendliness is increasing. They perform all the functions of LiDAR’s more sophisticated 3-dimensional (3D) imaging high-end relatives, but on a limited scale. There are a wide variety of apps in the Apple App Store to turn iPhones and iPads into handheld LiDAR platforms.
Apple also included the technology on its iPads. Apple began using LiDAR to improve its camera’s focusing abilities and it has been noticed by tech sites all over the internet. Would you be surprised to find a LiDAR (Light Detection and Ranging) system in your pocket? If you have one of the iPhone 12/13 Pro or Pro Max, you have it.
