From the obtained LIDAR data, we can generate the digital elevation model, which can be symbolized by a color ramp, special effects, such as the slope, can be used to simulate the relief.

The digital surface model gets the z coordinates of the value along with x and y. The elevation values ​​are specifically distinguished as; roads, buildings, bridges, vegetation, water, etc.
