Lidar Mass Points & Point Clouds
In addition to derived elevation products, we can provide source lidar data as either mass-points or full lidar point clouds. Specifications vary depending on sensor type, but typical deliverables are below:
Airborne Lidar and Terrestrial Mobile Lidar Data
These are typically .las file binaries with standard ASPRS lidar point classes compliant to LAS version 1.3 (32-bit) or 1.4 (64-bit) along with a return number for each point. Intensity returns are either normalized pseudoreflectance or radiometric grayscale.
Point3Data can provide several levels of .las file classification to suit specific requirements, including Ground (Class 2), Vegetation (Classes 3-5), Building (Class 6) and Model Key-Points (Mass Points) (Class 8). A subset of ground points, Mass Points can be used to quickly construct a surface which supports the generation 2-ft contours at a 95% confidence level, and are useful when working point cloud data in CAD or other non-GIS software.
