The point cloud is a collection of data points where a 3D coordinate system has been assigned. In geo-referenced photogrammetry with drone, the point cloud allows coordinates measurements of a terrain, create digital elevation models, orthorectified images and three-dimensional meshes.
Used in conjunction with traditional surveyland, it offers millions of extra coordinate points and an excellent reference source and comparisons in measurements.
