Terrestrial Laser Scanning (TLS) uses a precise laser beam and rotational measurements to return a millimeter accurate 3-dimensional set of point information on the surrounding landscape.
The GEF currently has two TLS instruments available for loan to UK researchers. One is a short range high speed time-of-flight scanner (Trimble X9 Premium). It has a range of around 150m which means that for many projects, multiple scans will need to be taken and joined together to cover the features typically of interest to environmental researchers. The fast scan speed and automated registration capabilities of our system makes this easy to accomplish.
The second scanner is a much longer range model (Riegl VZ-1000) with a maximum range around 1.4km. It is also a high-speed scanner (though not as fast as the short range model) and is ideal for situations where it is impossible to get close to the target being scanned.
