Ground (stationary) laser scanning (Ground Laser Scanning) is a method of studying the spatial structure of an object using a laser scanner installed at a point with known coordinates. If necessary, scanning is performed from several points. The laser beam directed at the object is reflected from its surface and returns to the receiver, where the signal delay time is analyzed. From this time, the distance to the object can be calculated.
Terrestrial laser scanning is used to create three-dimensional models of objects such as buildings, bridges, trees, etc. It allows you to get detailed information about the size, shape and position of the object, as well as its interaction with the environment within hundreds of meters.
On the plus side, high accuracy of several millimeters can be noted, and on the minus side, the speed of obtaining materials compared to Mobile or Airborne laser scanning.
