  • Ein Jahr WebApp „meinGrün“ – finale Befragung und Ergebnispräsentation

    Im Juni 2020 haben wir mit unseren Partnern aus dem meinGrün Projekt die gleichnamige WebApp gestartet. Nun sind die Nutzenden in Dresden und Heidelberg aufgerufen, sich ein letztes Mal an einer Befragung zu beteiligen und so Hinweise für die mögliche künftige Weiterentwicklung zu geben. Am 28. Juni werden wir zudem mit unseren Projektpartnern die Ergebnisse…

  • Measuring the tallest sequoias of Germany in student field campaign

    Last Fieldwork Friday, a group of students gathered in Arboretum I to capture Heidelberg’s sequoia trees in the frame of a 3D Sensor Practical. In small groups, the students learned surveying strategies via terrestrial laser scanning (TLS) and Global Navigation Satellite System (GNSS) measurements. It was one of the first joint field campaigns of our…

  • World Refugee Day: Mapathon by CartONG

    Whether you are a beginner or an advanced mapper, or just curious to learn more about why mapping is so important for humanitarian work, join us on 21 June.

  • Methods and algorithms for 3D/4D change analysis and virtual laser scanning

    Curious, which methods on 3D/4D point cloud-based change analysis and virtual laser scanning we are working on, that might also be interesting for your research? Thanks to a redesign of our 3DGeo website you can now quickly get an overview of algorithms and methods, that are acitvely developed in our research and featured in recent…

  • 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…

  • Becoming ohsome in R – analysis of the completeness of the road network and health sites in Jakarta

    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…

  • The ohsome quality analyst goes public on Github with new release 0.3.0

    The ohsome quality analyst (short: OQT) has been introduced at the beginning of this year and today we are proud to announce two updates. First, we  released the new version 0.3.0 which includes new OSM layers and a brand new data quality report. Working on this release has been the first collaboration with MapAction under…

  • All countries of Central and South America now on Open Healthcare Access Map

    After Sub-Saharan Africa and South and Southeast Asia we have now published all countries of Central and South America on the Open Healthcare Access Map. The web application is available here: https://apps.heigit.org/healthcare_access/. Please note that this is still a prototype and feedback on improvements and desired functionalities is very welcome. You can reach us at…
