A point cloud is a set of data that represents objects or space.
These points represent the X, Y and Z geometric coordinates of individual points on the surface to be recorded. A point cloud is a means of linking a large number of individual spatial measurements into a set of data that can then form a whole. When color information is present, the dot cloud becomes 4D.
The point cloud is most often generated using 3D laser scanners and LiDAR technologies and techniques. Here, each point represents one measurement by laser scanning. These scans then merge, creating a complete 3D / 4D image. The point cloud thus represents a digitized and virtualized real space from which spatial information about specific objects (point, line or surface) that are the subject of the recording is then extracted. GeoDigit is doing this with specialized software that serves to process such data.
