4D objects-by-change: Spatiotemporal segmentation of geomorphic surface change from LiDAR time series
How can surface change processes be detected and delineated in large time series of 3D point clouds? A paper on the extraction of 4D objects-by-change has just been published in the ISPRS Journal of Photogrammetry and Remote Sensing. It presents an automatic method for 4D change analysis that includes the temporal domain by using the…

SYSSIFOSS project @ 2nd symposium on satellite-based earth observation in Cologne
On November 12-13, Jannika Schäfer from KIT presented the SYSSIFOSS project at the 2nd symposium on satellite-based earth obersvation (2. Symposium zur angewandten Satellitenerdbeoachtung) in Cologne. SYSSIFOSS is a joint project between the Institute of Geography and Geoecology (IFGG) of the Karlsruhe Institute of Technology (KIT) and the 3DGeo Research Group of Heidelberg University. In…

The Importance of Monitoring Interval for Rockfall Magnitude‐Frequency Estimation
Rockfalls commonly exhibit power law volume-frequency distributions, where fewer large events are observed relative to more numerous small events. Within most inventories, the smallest rockfalls are the most difficult to detect and so may not be adequately represented. A primary challenge occurs when neighboring events within a single monitoring interval are recorded as one, producing…

PermaSAR project concluded with publication of final report
With the publication of the final report, the PermaSAR project is concluded. In the blink of an eye regarding timescales of permafrost monitoring, research within the project period covered diverse methods and analyses around the topic of permafrost and related thaw subsidence in Arctic tundra landscapes. The report (in German) provides all details on the…

Studying the impact of built environments on human mental health in everyday life – a review of methods published
Rapid worldwide urbanization benefits humans in many aspects, but the prevalence of common psychiatric disorders is increased in urban populations. While the impact of city living and urban upbringing on mental health is well established, it remains elusive which of the multiple factors of urban living convey risk and resilience for mental disorders. For example,…

Using OSM data to generate scenes for LiDAR simulations in HELIOS
A new tutorial for the 3DGeo‘s LiDAR simulation software HELIOS has been posted to the repository’s wiki page. It shows a simple way to generate scenes of real landscapes including building and vegetation models as well as terrain from NASA JPL’s SRTM data. When applied to OSM data in the city of Vienna, the obtained…

Classification of 3D ALS Point Clouds using End-To-End Deep Learning
In a new publication, we show how deep neural networks can be used in an end-to-end manner for the classification of 3D point clouds from airborne laser scan data. The research, based on the award-winning diploma thesis of Lukas Winiwarter at TU Wien, has now been published in “PFG – Photogrammetrie, Fernerkundung, Geoinformation“, the Journal…

Place in GIScience Paper at Platial 2019
The International Symposium on Platial Information Science PLATIAL’19 will be held this year at the University of Warwick in September 5-6. The programme has just been published and includes a paper from our research group about a systematic literature review about Place in the GIScience Community. As the first PLATIAL’2018 symposium held in Heidelberg 2018…
