-LiDAR Viewer is an application for visualizing and measuring 3D point cloud data, such as that collected via terrestrial or airborne LiDAR surveys. ​LiDAR Viewer uses a hierarchical data structure ​to store very large point clouds (>= 12 billion points) ​in a way that supports efficient processing ​and interactive ​visual exploration ​and analysis.+LiDAR Viewer is an application for visualizing and measuring 3D point cloud data, such as that collected via terrestrial or airborne LiDAR surveys. ​The software was developed to enable analysis of multi-billion-point lidar data sets without requiring binning, sub-sampling,​ decimation, or digital surface modeling. LiDARViewer enables real-time interactive visualization and analysis of datasets arbitrarily greater than computer’s main memory by optimizing data handling using hierarchical data structures and view-dependent,​ multi-resolution,​ out-of-core rendering. Point clouds are visualized with intensity coloring, user defined RGB coloring, or, to enhance feature recognition,​ a dynamic hillshading effect over which sun azimuth and elevation are adjustable in real-time. The point cloud remains fully manipulable ​in 3D at all times, so that interpretations ​and measurements can be evaluated from multiple viewpoints. In addition to interactive ​navigation, LidarViewer supports real-time point selection ​and extraction, fitting of geometric primitives (lines, planes, spheres, cylinders) to selected points, measurement of point locations and distances, visualization of point distances from a user-defined plane via plane-perpendicular adjustable color gradients, and extraction of profile curves. LidarViewer communicates with proprietary data management programs so that quantitative measurements can be easily exported, managed, and integrated into a data analysis ​workflow
