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 this project [...]

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. [...]

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 work [...]

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 3D [...]

Within the BMBF-funded project ER3DS (Emission Reduction in Smart Cities Using 3D Spatial Sensing and Analysis) a second workshop and exchange visit was organized and hosted by the National Cheng Kung University (NCKU) in Tainan, Taiwan, from 16 September to 19 September 2019.
The first day included two lectures at the Dept. of Geomatics (Prof. Wang), [...]

How do the dynamics of surface change on a rock glacier look like over an entire summer season?
And how is rockfall activity and storage and talus supply from the headwall of a rock glacier related to patterns of its movement?

These and other questions are currently investigated within the AHK-4D and Geomorph4D projects of the 3DGeo [...]

Change analysis of rock glaciers is crucial to analyzing the adaptation of surface and subsurface processes to changing environmental conditions at different timescales because rock glaciers are considered as potentially unstable slopes and solid water reservoirs. To quantify surface change in complex surface topographies with varying surface orientation and roughness, [...]

Namibia is a dry and low populated country highly dependent on agriculture, with many areas experiencing land degradation accelerated by climate change. One of the most obvious and damaging manifestations of these degradation processes are gullies, which lead to great economic losses while accelerating desertification.
The development of standardized methods to [...]

Todays data production, maintenance, and use have changed in the last years.  While these tasks were reserved to professionals until a few years ago, the situation has changed.  This is no different in the geographical domain. Volunteers gather general information in Wikipedia and geographical information in OpenStreetMap.  Twitter users provide not only text snippets but [...]

Very interesting terrestrial laser scanning and terrestrial and UAV image datasets of different Alpine sites in Austria have just been openly provided on PANGAEA. The data are related to the first (2015) and second (2017) edition of the Innsbruck Summer School of Alpine Research - Close Range Sensing Techniques in Alpine Terrain and can, for [...]
