From LiDAR Magazine… Lidar, which can generate up to 10 million pulses per second or more, creates a dense terrain model of unmatched accuracy when compared to manual photogrammetric collection. As a result, it is the most efficient three-dimensional modeling and surveying method available.
There are multiple lidar sensor technologies available and others in development, with varying data collection factors for multiple data applications.
Linear mode lidar has been the most conventionally used aerial lidar approach for several years. Recently, the advent of single photon and Geiger-mode lidar sensors have brought new methods and applications of lidar collection to light.
These advancing technologies have raised the question–especially for those currently making long-term, large-scale investments in these services–as to whether one aerial lidar methodology will emerge and eclipse the others or whether the industry will support multiple lidar methodologies.
Given the breadth of projects utilizing this technology and the varying applications of the data, I believe not only will a variety of aerial lidar methodologies continue to coexist, but that the data delivered to clients will be more affordable and specific to a growing array of client needs.
