BiographyChristoph Fürst was born in Vienna, Austria, in 1993. After graduating from Technical College in 2012, he joined the military service and then spent 4 months studying Spanish in Panama. He joined the international sales department of RIEGL Laser Measurement Systems in September 2013. His speciality is terrestrial laser scanning and he has already carried out several trainings for international RIEGL customers.Abstract How much of a historic town can be mapped by the fastest high-end terrestrial laser scanner within a working day? Downtown Vienna with its world-famous cultural sites and architectural features is most definitely worth conservation. One way to at least archive a digital 3D imprint is by laser scanning. While urban mapping with airborne or mobile laser scanning is fast and efficient, the resulting point clouds might not have the required resolution or experience gaps due to shadowing. Terrestrial laser scanning has the potential to overcome these limitations, however, it has long been considered time-consuming and labor-intensive both while capturing and also while processing the data. In order to challenge this, we performed a field test with the new RIEGL VZ-400i terrestrial laser scanner. For eight hours, during the night from 2nd to 3rd of June 2016, one single operator employed the instrument throughout the city centre of Vienna. He managed to take 514 high-resolution laser scans with approximately 10 meters distance between the scan positions. The data acquired in the course of this test impressively demonstrates the potential of state-of-the-art terrestrial laser scanning. This paper describes the complete workflow from the one touch operation in the field up to the automatic registration process.
