Analysing the Impact of Large Data Imports in OpenStreetMap
Posted in OSM, Publications, Research on Aug 6th, 2021
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 [...]

The ohsome region of the month blog post series is back and since it’s summer this time we’re taking you to the coast. Before that happens, if this is your first blog post of this format you might want to take a look at former blog posts of this series for example one on railway networks or [...]
OSM data quality analysis for different stages of the mapping process
Posted in OSM, Publications on Jun 23rd, 2021
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. [...]
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. [...]

AGILE is the Association of Geographic Information Laboratories in Europe and the 2021 conference is for the first time held as a virtual conference. As in earlier years GIScience Heidelberg and HeiGIT are contributing to the conference with several [...]
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 [...]
Data quality is an important issue then performing analysis based on OpenStreetMap data. We have recently demonstrated how the effects of the 2013 flood in Jakarta on the accessibility of hospitals and clinics could be analyzed based on network analysis indicators and the isochrones functionality of the openrouteservice. As part of that analysis we analyzed [...]
