Automatic mapping of national surface water with OpenStreetMap and Sentinel-2 MSI data using deep learning
Large-scale mapping activities can benefit from the vastly increasing availability of earth observation (EO) data, especially when combined with volunteered geographical information (VGI) using machine learning (ML). High-resolution maps of inland surface water bodies are important for water supply and natural disaster mitigation as well as for monitoring, managing, and preserving landscapes and ecosystems. In…

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…

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…

Routenplanung im Überflutungsgebiet: openrouteservice nutzt Copernicus EMS Flut-Daten in spezieller Lösung
Die aktuelle Flut in Deutschland hat zahlreiche Straßen in den betroffenen Gebieten zerstört oder temporär unpassierbar gemacht. HeiGIT arbeitet an freien und offenen, auf Geodaten-basierten Lösungen für die humanitäre Hilfe. Hierzu zählen insbesondere Routenplanung unter Berücksichtigung aktueller Katastrophendaten wie z.B. Überflutungsgebiete und zerstörter Strassen. Für die aktuelle Flutkatastrophe in Deutschland und Nachbarstaaten hat HeiGIT nun…

New paper on OSM feature completeness modelling accepted for AGIT symposium
The availability of data on public transport is a prerequisite for numerous spatial data applications such as routing, accessibility analyses or route planning. OpenStreetMap (OSM) – as a global platform for Volunteered Geographic Information – is one of the options for sharing public transport data. The data completeness on OSM, however, is characterized by heterogeneity. Results…

OSM Changeset Analysis with Humstats and the ohsome Framework
In this blog post we want to take a closer look at a fruitful mapping collaboration between humanitarian organizations and corporations. Since 2015 mapping remote areas in OSM is one part in the cooperation between the leading savings, retirement and insurance company, Aviva, and the British Red Cross (BRC). By combining multiple datasets we analyzed…

OSM data quality analysis for different stages of the mapping process
Slums are an important operational area for humanitarian organisations: Because of provisional housing, poor sanitation and difficult socio-political circumstances offers of help from such organisations are important and often necessary. For such deployments, humanitarian actors rely heavily on Volunteered Geographic Information (VGI), as official maps and data are often incomplete. This makes it all the…

Monitoring OSM and Tasking Manager to Map 1 Billion
In 2020, the Humanitarian OpenStreetMap Team (HOT) received funding from seven donors through TED’s Audacious Project. This has accelerated HOT’s ambition to map an area home to one billion people. HOT is working to add places at high risk of natural disaster or experiencing poverty to OpenStreetMap by significantly scaling-up support for local mapping communities.…
