The evolution of humanitarian mapping within the OpenStreetMap community
In the past 10 years, the collaborative maps of OpenStreetMap (OSM) have been used to support humanitarian efforts around the world as well as to fill important data gaps for implementing major development frameworks such as the Sustainable Development Goals (SDGs). In a recently accepted paper we provide a comprehensive assessment of the evolution of…

Humanitarian OSM Stats: How to monitor humanitarian mapping in the HOT Tasking Manager? – Part 2
Since 2010 organized humanitarian mapping has evolved as a constant and growing element of the global OpenStreetMap (OSM) community. With more than 7,000 projects in 150 countries humanitarian mapping has become a global community effort. Due to this large amount of projects it can be difficult to get an overview on mapping activity. This is…

3D Winter Wonderland – Multi-method acquisition for snow process research
A joint field campaign was conducted this week in the snow-covered black forest (Hundseck, 48.643°N, 8.228°E) by the research groups Hydrology and Climatology (Prof. Menzel) and 3DGeo (Prof. Höfle). Regular in-situ surveys are conducted at the site to investigate snow as crucial component of the hydrologic cycle, forest management, and evapotranspiration. Surveys comprise measurement of…

Updated OSM Healthcare in Senegal (2020)
OpenStreetMap (OSM) offers many possibilities and holds potential in the area of freely available infrastructure data for the health sector. Nevertheless, it is important to underline that the quality of the information is different in each country, since the mapping activity is strongly affected by the size of the community of volunteers. Monetary barriers prevent…

Accessibility to pharmacies in Germany with 15km Covid-19 restriction
Current lockdown regulations in Germany state that – in many but not all federal states – travel in COVID-19 hotspot regions is only allowed up to 15km distance. This has raised concerns since a 15km radius has been perceived by some as a serious constraint especially in rural regions. Clearly, this might prevent visits to…

4D change analysis for improving our understanding of dynamic landscapes
Time series of topographic point clouds offer great possibilities to advance our understanding of dynamic landscapes. To exploit the full information these 4D datasets contain on spatial and temporal properties of natural surface changes, the 3DGeo research group is developing methods for 4D change analysis. These methods are required to answer fundamental questions on the…

Accessibility of covid-19 vaccination centers in Germany
Updated based on newly available vaccination center locations at the 14th of January 2021. Vaccination of a sufficiently large share of the population is considered the most important action to fight the spread of SARS-CoV -2 and resulting COVID-19 infections. Germany has started together with the majority of EU member states at the 27th of…
