Impulse aus der Corona-Krise
“International erfolgreiche Wissenschaft ist bislang untrennbar verknüpft mit weltweiter Reiseaktivität. Der vor allem durch Flugreisen verursachte Treibhausgasausstoß steht im Widerspruch zum Klimaschutz. Die Corona-Krise wirkte disruptiv auf etablierte Praktiken des Austauschs und zeigte plötzlich Wege auf, die zuvor kaum denkbar waren. Doch was passiert nach der Pandemie? Wie kann es gelingen, auf den Erfahrungen aufbauend,…

A Web App to generate and disseminate knowledge on urban green space qualities and their accessibility
Urban green spaces (UGSs) can provide important ecosystem services for citizens and their well-being. To make use of these services according to UGS user demands, urban residents, tourists, and city administrations should know where UGSs are located, what qualities they have and how to reach them on convenient routes. A new open access paper at…

New paper: Opaque voxel-based tree models for virtual laser scanning in forestry applications
In the SYSSIFOSS project, we are investigating how we can take advantage of virtual laser scanning (VLS), the simulation of laser scanning in a computer environment, in forestry applications. These applications include survey planning and optimization, sensitivity analyses, and algorithm development. For example, VLS may be used to investigate the influence of different sensor and…

Multi-source 3D point cloud acquisition at the AHK rock glacier
Within the AHK-4D project, we continually monitor topographic change at the alpine rock glacier Äußeres Hochebenkar in Austria. Based on multitemporal and multi-source 3D point clouds at up to two-week acquisition intervals, we are developing methods to quantify the magnitudes and frequencies of individual processes of topographic change over varying timescales. This year, we have…

Analysing the Impact of Large Data Imports in OpenStreetMap
OpenStreetMap (OSM) is a global mapping project which generates free geographical information through a community of volunteers. OSM is used in a variety of applications and for research purposes. However, it is also possible to import external data sets to OpenStreetMap. The opinions about these data imports are divergent among researchers and contributors, and the…

The role of data in transformations to sustainability: a critical research agenda
A recently published article in ‘Current Opinion in Environmental Sustainability‘ investigates the role of digital technologies and data innovations, such as big data and citizen-generated data, to enable transformations to sustainability. We reviewed recent literature in this area and identified that the most prevailing assumption of work is related to the capacity of data to…
