(point cluster)

A point cloud is a network of georeferenced points. Such a three-dimensional point cloud is the result of LIDAR measurements, where a spatial assignment is made for each point in the vector space by means of a big data analysis. The cloud of data points is described by the points it contains, each of which is captured by its spatial coordinates. This approach enables the representation of a surprisingly accurate 3D model of reality. In this context, the point density is an essential factor for the detection of objects and the possible resolution the in the field of visualization.
