Version 1.0 of the ohsome quality API and ohsome dashboard
At HeiGIT and in particular within the ohsome team, we strive to provide valuable insights into OpenStreetMap (OSM) data. The ohsome API offers aggregated statistics on the evolution of OSM elements since 2020. These are made easily accessible by the ohsome dashboard. With the ohsome quality API, previously called ohsome quality analyst (OQT), we continue…

Visualizing OQT API Results in QGIS
Using the ohsome dashboard, it is possible to explore quality estimation for OpenStreetMap (OSM) data from the ohsome quality analyst (OQT) for arbitrary regions. Also, OQT does provide an API to programmatically fetch quality estimation for a lot of different regions in one request. Chances are that one wants to visualize the results on a…

Bachelor’s thesis: Using OSM for location analyses of residential real estate projects – an extrinsic analysis of data quality
In his bachelor’s thesis, supervised by HeiGIT’s apl. Prof. Dr. Sven Lautenbach, Lars Reckhaus examined the suitability of OpenStreetMap (OSM) for location analyses in the context of residential real estate projects. Typically, such analyses require the use of a variety of data sources and are mostly performed manually. For this reason, they tend to be…

Introducing ohsomeNow stats: Real-Time Monitoring for OpenStreetMap Contributions
You can now monitor contributions to OpenStreetMap (OSM) in real time with ohsomeNow stats! We developed this new dashboard as part of our long-term cooperation with the Humanitarian OpenStreetMap Team (HOT), an international organization dedicated to humanitarian action and community development through open mapping. This dashboard replaces the Missing Maps Leaderboard with a comprehensive overview of…

Recap Road Quality Mapathon
Last Monday, on July 31st, we hosted a road quality mapathon, which saw the participation of students and researchers alike. Their collective efforts led to the classification of nearly 50% of all the pre-selected road pictures in 34 African countries. These valuable data points will be instrumental in training machine learning algorithms to identify paved…
