High-frequency and high-resolution monitoring of rock glacier dynamics
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…

Green spaces in cities promote well-being and mental health — ‘Nature’ Neuroscience study published with participation of GIScience researchers at Heidelberg University
INTERDISCIPLINARY NATURE STUDY SHOWS THAT INNER TOWN GREEN DIRECTLY INFLUENCES ON CITY RESIDENTS Inner city green areas such as lawns, flowerbeds, trees or parks can directly improve the well-being of city dwellers. These are the findings of a recent study conducted by scientists from GIScience Research Group at Heidelberg University and the Heidelberg Institute for…

Feasibility of Using Grammars to Infer Indoor Room Semantics
Current indoor mapping approaches can detect accurate geometric information but are incapable of detecting the room type or dismiss this issue. A recently published paper investigates the feasibility of inferring the room type by using grammars based on geometric maps. Specifically, we take the research buildings at universities as examples and create a constrained attribute…

Mapping Human Settlements with Higher Accuracy and Less Volunteer Efforts by Combining Crowdsourcing and Deep Learning
Our new paper on Machine Learning and Humanitarian Mapping Nowadays, Machine Learning and Deep Learning approaches are steadily gaining popularity within the humanitarian (mapping) community. New tools such as the ML Enabler or the rapId editor might change the way crowdsourced data is produced in the future. Hence, at the Heidelberg Institute for Geoinformation Technology…

New ORS Jupyter example about Fleet Scheduling for Disaster Response with ORS and VROOM
Routing optimization in a humanitarian context Routing optimization generally solves the Vehicle Routing Problem (a simple example being the more widely known Traveling Salesman Problem). A more complex example would be the distribution of goods by a fleet of multiple vehicles to dozens of locations, where each vehicle has certain time windows in which it can operate…

Waterproofing Data: Pilot Study in Brazil
A pilot study for the Waterproofing Data project took place in Brazil (Rio Branco and São Paulo) last month. Carolin Klonner from the GIScience team and researchers from the UK and Brazil focused on testing the developed methods in the specific setting of the study areas and on exploring the flood mitigation measures taken by…

meinGrün @roadto_festival: What OSM tells us about urban green space features
Where is the next shaded bench to escape the burning heat? Where can I play soccer within the city and later on have a barbecue with my friends? All of these questions require information about features of urban green spaces. Although it is easy to find the right place within your own neighbourhood, it is…

Multi‐temporal 3D point cloud‐based quantification and analysis of geomorphological activity at an alpine rock glacier using airborne and terrestrial LiDAR
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, a full three‐dimensional (3D) change…
