From forest stand information to laser scanning #pointclouds without a real scanner?

📢 📰 In our new paper by Schäfer et al. (https://doi.org/10.1093/forestry/cpad006) we generate realistic laser scanning data of forests by combining
➡️ forest stand information ℹ️
➡️ the #pytreedb tree point cloud database 🌳(https://pytreedb.geog.uni-heidelberg.de)
➡️ and the laser scanning simulator #HELIOS++ 🖥️(https://github.com/3dgeo-heidelberg/helios)

Such simulated data may be used in sensitivity analyses, for algorithm development, and for #machinelearning.

Generating synthetic laser scanning data of forests by combining forest inventory information, a tree point cloud database and an open-source laser scanning simulator

Abstract. Airborne laser scanning (ALS) data are routinely used to estimate and map structure-related forest inventory variables. The further development, refin

Geologie: Erwärmung macht Blockgletscher instabil

Im Tiroler Ötztal wird ein Blockgletscher, ein hangabwärts fließendes Stein-Eis-Gemisch, durch die steigenden Temperaturen instabil. Neue Messungen zeigen, dass sich die Fließgeschwindigkeit im unteren Bereich des Blockgletschers stark erhöht hat, wodurch es häufiger zu Steinschlag kommt.

Peter Anich – Ein Bauer greift nach den Sternen

Anlässlich des 300. Geburtstages von Peter Anich hat sich die Redaktion des ORF Tirol in einem Österreich Bild den Errungenschaften des Multitalentes gewidmet und deren Bedeutung für die moderne Vermessung Tirols. Österreich Bild, 19. Februar, ORF 2.

Apps, Drohnen und Co

Seine Errungenschaften sind die Basis der modernen Vermessung, die heute hoch technologisiert auch für die Abschätzung von Naturgefahren angewandt wird. Zurzeit werden mit Apps, Satellitenbildern, Drohnen und 3D-Laserscan-Methoden räumliche Daten zur Kartenerstellung verwendet. Ein komplexes Unterfangen, wobei dennoch die Arbeit im Gelände erforderlich ist.
