+Airborne LiDAR systems are a common source of acquisition for elevation. They provide point clouds with higher and higher density.
+
+LiDAR point clouds consist in 3D spatial data, with a set of points defined in space by x, y and z.
+
+In addition to that, LiDAR point clouds comes with features extracted from the capture such as 
+- the laser intensity at the returned point,  
+- The number of echoes a pulse have returned, for some surfaces such as vegetation, the laser go through leaves of small branches and then can return several echoes, for example one point at the top of the canopy, and one point at the ground under the tree.
+- and other metadata from the flight
+
+some LiDARs are multispectral now, so we can also have several point cloud of the same scenery with intensities or number of echoes dependings of the wavelength.
