Multi-method field course in an aeolian sand dune field
This week, the research groups Geomorphology and 3DGeo of the Institute of Geography at Heidelberg University are conducting a field course in the aeolian sand dune field Erg Chebbi in Morocco. The current field course is the second edition of “HeidelErg“. The aim is to teach students different methods of data acquisition for physical geography,…

Multitemporal Terrestrial Laser Scanning Point Clouds for Thaw Subsidence Observation
New paper on “Multitemporal Terrestrial Laser Scanning Point Clouds for Thaw Subsidence Observation at Arctic Permafrost Monitoring Sites” The paper investigates different methods for quantifying thaw subsidence using terrestrial laser scanning (TLS) point clouds. Thaw subsidence is a slow (mm‐cm per year) vertical displacement of the ground surface common in ice‐rich permafrost‐underlain landscapes. It is…

ISSAR19 – Third Innsbruck Summer School of Alpine Research
Close-range sensing techniques in Alpine terrain have been taught in the frame of a bi-annual ISPRS summer school since 2015. This week, a group of 40 young researchers (mainly PhD students) is participating in the third edition of the summer school to learn about various sensors, processing techniques, and analysis methods for different topics in…

Continuing ground-based measurements at Arctic research site
For the fourth consecutive year, ground-based measurements of the dynamic, permafrost-underlain tundra landscape have been continued in Trail Valley (68°44’25” N 133°29’36” W). A team of permafrost researchers from the Alfred Wegener Institute (AWI) for Polar and Marine Research around PD Dr. Julia Boike conducted the measurements as part of a large expedition to the Canadian Northwest…

4D-LiDAR Snow Cover Monitoring at the Highest Summit of Germany
The all-new terrestrial laser scanner (TLS) of the 3DGeo group (Prof. Bernhard Höfle) has been set up at the Environmental Research Station Schneefernerhaus over one week (mid of April 2018) to capture a unique highly temporal time series of the melting and degrading snow cover during the April’s week with the warmest daily maximum temperatures…

Auto3Dscapes Makes Environmental Monitoring Smarter
… by acquiring data only when and where changes occur. In this project on Autonomous 3D Earth Observation of Dynamic Landscapes (Auto3Dscapes), a novel strategy of permanent 3D observation will be developed incorporating observed topographic changes as feedback and dynamically adapting the acquisition parameters and analysis methods. Permanent 3D Earth observation is currently challenged by…

Sunny field trip of laser scanning course
On 7th of July, the summer semester’s laser scanning course was on a field trip for capturing a gravel bar of the river Neckar next to Ilvesheim. Apart from the main goal of experiencing ‘real life scanning’, the produced data now is used in various analyses: Based on two other datasets from 2011 and 2012***,…

LiDAR Research Group completes multitemporal multisensor data for boosting quality of plant growth models
On 19th of June, a multitemporal data set of agricultural plants was completed by researchers of the Chair of GIScience‘s LiDAR Research Group in the course of the projects Hyland and ESOB. A field of several grain varieties and fertilization quantities in maximum growth stage was captured in 3D using a terrestrial laser scanner (TLS).…
