Automatic building detection with ohsome2label and Tensorflow
Accurate and complete geographic data of human settlement is crucial for humanitarian aid and disaster response. OpenStreetMap (OSM) can serve as a valuable source, especially for global south countries where buildings are largely unmapped. In a previous blog, we introduced our recent work in detecting OpenStreetMap missing buildings, so this time we will show you…

Two-part Mapathons for better new user retention?
The project “25 Mapathons“ goes into the next phase. Based on the experience of until today 17 OSM mapathons with German Red Cross (GRC) chapter and an extensive literature review on the success of mapathons, the “25 Mapathons” team has identified several points of possible improvement in the way how mapathons are conducted in general:…

Towards a framework for the analysis of local OSM contributions
Volunteered Geographic Information (VGI) such as OpenStreetMap (OSM) is often defined as the collaborative acquisition of geographic information and local knowledge by volunteers, amateurs or professionals (Goodchild, 2007). The increasing availability and importance of local data in OSM is largely acknowledged in VGI projects. Local knowledge provides access to a plethora of contextual information and…

Humanitarian OSM Stats: How to monitor humanitarian mapping in the HOT Tasking Manager? – Part 5: the American Red Cross
Since 2010 organized humanitarian mapping has evolved as a constant and growing element of the global OpenStreetMap (OSM) community. With more than 8,000 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…

Flood Impact Assessment on Road Network and Healthcare Access at the example of Jakarta, Indonesia
Extreme natural events create catastrophic situations for cities and their populations. Due to climate change and anthropogenic activities, the number and intensity of these events has steadily increased at the global scale. Floods are the most common natural disaster worldwide, responsible for economic, social and life losses. Low-income countries have a death rate 23 times…
