Second expedition in the Mackenzie Delta
Mid of August we started for our second field trip in the Canadian Arctic. This time the team consisted of Inga Beck, Sabrina Marx and Detlef May. As Sabrina already joined the trip in June, many things – such as customs, security etc. worked much easier than in June. We only had very little time…

Systematic review of current efforts to quantify the impacts of climate change on undernutrition
Malnutrition is a challenge to the health and productivity of populations and is viewed as one of the five largest adverse health impacts of climate change. Nonetheless, systematic evidence quantifying these impacts is currently limited. Our aim was to assess the scientific evidence base for the impact of climate change on childhood undernutrition (particularly stunting)…

First Arctic Expedition for 3D Earth Observation of Permafrost (Mackenzie Delta, Canada) within our PermaSAR Project
In June 2015 the LiDAR Research Group (LRG), Heidelberg University, performed a joint expedition with the Alfred-Wegener Institute (AWI). This was our first field expedition within the PermaSAR research project, which is funded by the BMWi / German Aerospace Center (DLR) from 2015 to 2018. The project PermaSAR aims at developing a novel method for…

How to find the fastest way out of a dense human crowd using your smartphone?
In our research “Routing in Dense Human Crowds Using Smartphone Movement Data and Optical Aerial Imagery“, we propose a navigation approach for smartphones that enables visitors of major events to avoid crowded areas or narrow streets and to navigate out of dense crowds quickly. Two types of sensor data are integrated. Real-time optical images acquired…

Mon-Shieh Yang successfully completes his PhD
Mon-Shieh Yang successfully defended his PhD thesis at the National Cheng Kung University (NCKU) in Taiwan. We cordially congratulate him! Mon-Shieh was member of the Heidelberg GIScience Team for almost one year (until May 2015). He was performing research with the LiDAR Research Group (LRG) where he investigated the derivation of novel LiDAR-based roughness measures…

3D Field Trip to Greece – Exploring 3D GIScience in one of the most exciting geological settings
Our students learned how multiple 3D geodata sensor systems (LiDAR, UAVs, GNSS) can be used to capture and analyze the geomorphology and geology of one of the most exciting geological areas, the Peloponnese in Greece. Together with the geology students from the University of Stavanger more than 30 young researchers explored the area around the…

Geo-reCAPTCHA: Crowdsourcing large amounts of geographic information from earth observation data
With the Geo-reCAPTCHA we present a new concept for crowdsourcing of vast amounts of geoinformation by micro-mapping tasks. The paper can be downloaded free of charge (until 22 May 2015). In our study we investigated the possibilities and limitations of capturing building footprints via Geo-reCAPTCHA based on remote sensing imagery. We could analyze more than…
