Beyond 3-D: The New Spectrum of LiDAR Applications for Earth and Ecological Sciences
Capturing and quantifying the world in three dimensions (x,y,z) using light detection and ranging (lidar) technology drives fundamental advances in the Earth and Ecological Sciences (EES). However, additional lidar dimensions offer the possibility to transcend basic 3-D mapping capabilities, including i) the physical time (t) dimension from repeat lidar acquisition and ii) laser return intensity…

3D data acquisition in the Ötztal Alps – Exploring 3D GIScience on the “Monster of Rock”
As part of the practical field training “3D Geodatenerfassung im Hochgebirge (Ötztal), 31 July – 06 August”, the rock glacier “Äußeres Hochebenenkar” (42 ha), located in the Ötztal Alps in an elevation of 2,630-2,800 m a.s.l., was explored by 16 students under the direction of Bernhard Höfle, Stefan Hecht and Martin Hämmerle. With the help…

Impressions from ISPRS Congress 2016 in Prague
As we mentioned earlier, we contributed four papers to the ISPRS congress and participated in the CATCON contest for brilliant Computer Assisted Teaching tools. Our new LiDAR Simulator called HELIOS developed by Sebastian Bechtold received a lot of attention. You can also find us in this video of congress day 3. Our young researchers Katharina,…

Local-scale flood mapping on vegetated floodplains from radiometrically calibrated airborne LiDAR dat
Knowledge about the magnitude of localised flooding of riverine areas is crucial for appropriate land management and administration at regional and local levels. However, detection and delineation of localised flooding with remote sensing techniques are often hampered on floodplains by the presence of herbaceous vegetation. To address this problem, our very recent paper presents the…

New publication: ‘Terrestrial and unmanned aerial system imagery for deriving photogrammetric three-dimensional point clouds and volume models of mass wasting sites.’
The results of a study dealing with photogrammetric 3D geodata of mass wasting sites conducted at the GIScience were considered to be worth publishing in the Journal of Applied Remote Sensing: ‘Terrestrial and unmanned aerial system imagery for deriving photogrammetric three-dimensional point clouds and volume models of mass wasting sites.‘ Three-dimensional (3D) geodata of mass…

3D Participatory Sensing for Crop Height Assessment
Participatory Sensing (PS) is a concept which enables laymen to easily gather geodata with standard low-cost mobile devices, offering new and efficient opportunities for agricultural monitoring. The integration of local agricultural knowledge may help to better understand complex phenomena such as the association between climate variability, crop yields and undernutrition. In our new study we…

Autonomously Operating Low-Cost Static Terrestrial LiDAR
In order to optimize agricultural processes, near real-time spatial information about in-field variations, such as crop height development (i.e., changes over time), is indispensable. This development can be captured with a LiDAR system. However, its applicability in precision agriculture is often hindered due to high costs and unstandardized processing methods. In our new study we…
