Airborne Laser Scanning

(LiDAR = Light Detection And Ranging)


ESTOL | SSTOL - Gyrocopter systems


Airborne laser scanning is a rapid, highly accurate and efficient method of capturing 3D data of large areas, such as agricultural or forestry sites, urban areas, industrial plants, etc.


Laser scanners make use of the latest state-of-the-art laser and signal processing technology. They are exceptionally compact, lightweight and cost effective, and are designed to meet the most challenging requirements in airborne surveying.




In the case of Airborne Laser Scanning (ALS), the scanning unit is mounted on a flying object (usually on an airplane or helicopter). The surface of the earth is scanned by means of a laser beam. The distance between the detected point at the earth's surface and the sensor is determined. The surface models developed from the height information obtained nowadays are used in many areas of expertise.




The beginnings of the ALS can be found in the USA and Canada. They date back to the 1970s. At that time it was already known that air-supported LiDAR systems can measure the distance between aircraft and ground surface with an accuracy of less than one meter. However, elevation measurements using aircraft lasers were not used for topographical mapping for two reasons. One of the problems was that the vertical position of the flight system and the horizontal of the light cone on the ground surface were not to be detected in the required accuracy. This difficulty was fixed by the GPS at the end of the 1980s. By using a Differential Global Positioning System (DGPS), the horizontal and vertical position of the scanner could be determined centimeter-accurately. Laser scanning from the air was also made possible by the technical development of the laser. Pulse lasers were now able to emit light in the wavelength range of the near infrared, which could be clearly registered by the receiver after scattering and reflection on the ground surface. The high geometric accuracy of the method and the potential for the creation of digital elevation models was demonstrated by experiments at the University of Stuttgart between 1988 and 1993. The devices and the method developed rapidly since then by means of important insights into the system parameters. Nowadays the ALS is an integral part of many areas and is used in numerous fields.





An aircraft-based laser scanning system consists at least of the following components:


  • Laser distance meter: this contains the laser, transmitter for the laser beam, signal receiver for the reflected beam, amplifier and timer;
  • A system for georeferencing: GPS receiver and inertial navigation system (INS)
  • Storage medium for the laser, GPS, INS data and possible image data


Optionally, the systems can be combined with other sensors such as digital cameras and video cameras to record image data in addition to the altitude information. These components are attached to the aircraft using a bracket. The scope of delivery of a laser scanning system also includes the software for flight planning as well as for the evaluation of the raw data (from laser scanners and GPS). Parameters such as the measuring rate, scan angle and frequency can be set on the respective scanning system. Together with variable airports and flight speeds, Data density can be adapted to different application areas





A laser scanner is an active system that emits light pulses that are reflected by object points. The object point must be visible at least in one direction. Precondition is diffuse reflection on the surface. This technique works independently of the solar lighting. The use of laser scanning systems allows the acquisition of large amounts of 3D information on the surface of the earth at very fast acquisition rates. Depending on the recording of the back-radiation, two types of sensors are distinguished: 'Discrete Echo' sensors, and 'Full-wave systems'. The former detect only a small number of echoes, while second ones are able to register the entire time-dependent variation of the received signal strength. Thus, one can derive additional parameters, such as the signal amplitude or the echo width, from `full-wave 'data. The investigation area is flown in individual, overlapping flight strips. These usually have a length of several kilometers and a width of several hundred meters, depending on the airport over ground as well as the maximum scan angle.
