Abstract: Systems and methods for surveying ground environments and processing LiDAR data are disclosed. In an aspect, LiDAR data in the form of point clouds are adjusted or manipulated by a processor in order to improve the accuracy of the LiDAR data and make the data more useful for surveyors, builders, and the like. Systems and methods described herein may improve LiDAR point cloud data by aligning one or more LiDAR point clouds with LiDAR point clouds of the same environment of known high accuracy. Systems and methods described herein are further directed to techniques for reprojecting LiDAR datasets from a first coordinate system to a second coordinate system with better efficiency and processing speed than existing techniques.
