  • New paper: Capturing complex star dune dynamics – repeated highly accurate surveys combining multitemporal 3D topographic measurements and local wind data

    Morphologies of highly complex star dunes are the result of aeolian dynamics in past and present times. These dynamics reflect climatic conditions and associated forces like sediment availability and vegetation cover, as well as feedbacks with adjacent environments. However, an understanding of aeolian dynamics on star dune morphometries is still lacking sufficient detail, and their…

  • ohsomeHeX with Quality indication from OQT

    The HeiGIT team had a great time at the State of the Map 2022 in Florence. Many thanks to the participants for the fruitful discussions at our workshop! Despite the direct use of OSM as a map, more and more organizations use OSM as a source of data for activities, services, or applications. “How good…

  • Human-in-the-loop development of spatially adaptive ground point filtering pipelines — An archaeological case study

    LiDAR data have become indispensable for research in archaeology and a variety of other topographic applications. To derive products (e.g. digital terrain or feature models, individual trees, buildings), the 3D LiDAR points representing the desired objects of interest within the acquired and georeferenced point cloud need to be identified. This process is known as classification,…

  • Open Healthcare Access Map Update and HDX

    Last year we started the Open Healthcare Access Map.  Initially, only a few countries and later on continents were featured. Today, we are pleased to announce that we are releasing a number of previously missing countries, achieving global coverage. The Open Healthcare Access Map uses healthcare facilities extracted from OpenStreetMap, the isochrone method from openrouteservice…

  • Integrating Bird Observations from Community Projects and Social Media

    Environmental developments create an ever increasing need for monitoring and protection measures. These efforts are often based on digital or technical solutions like data analyses or modelling. Yet, in order to enable effective, reliable and large scale environmental monitoring and protection techniques, large information volumes are required. In a recently published paper, we analyse different…

  • Aktivierung des Disaster openrouteservice für Überschwemmungen in Pakistan

    In den vergangenen Wochen hat die Monsunflut in Pakistan über 1.000 Tote gefordert und Millionen Menschen ohne Dach über dem Kopf hinterlassen. Da Berichte und Fotos von rapide steigenden Lebensmittelpreisen, Bewohnern, die durch schultertiefes Wasser waten und Satellitenbilder von überfluteten Flüssen das Ausmaß dieser Katastrophe unterstreichen, hat das HeiGIT den Disaster openrouteservice für diese Region…

  • Disaster openrouteservice response to Pakistan flooding

    Over the past weeks, monsoon flooding in Pakistan has left over 1,000 dead and millions without homes. As reports and photos of skyrocketing food prices, residents wading through shoulder-deep water, and satellite images of flooded rivers highlight the magnitude of this catastrophe, HeiGIT has created an activation of the Disaster openrouteservice for that region. Currently, data is…

  • New feature addition to Ohsome Quality analysT: Building Completeness Indicator

    Introduction Since the release of the ohsome quality analyst (short OQT) in February of last year, we have been working on developing an accessible yet powerful toolkit which provides end users insights on the quality of OpenStreetMap (OSM) data. An overview of the functionality additions made to OQT over this period of time can be found…

  • Gefahrenstellen.de Uses ORS for a Safer Route to School

    Creating tools to map and navigate the urban (and not-so-urban) jungle has been a specialty of the HeiGIT and GIScience teams since their founding. We’ve plotted our way to the closest park through meinGrün, fostered awareness of barriers for limited-mobility travelers with CAP4Access, and helped find shortcuts through the unprecedented heat with HEAL. The latest…

  • GIScience and HeiGIT at SotM 2022

    We are happy to announce that, this year, GIScience and HeiGIT has had four contributions to the FOSS-Community “conferencathon” in Florence. As QGIS-Meeting, State of the Map, HOT unSummit and FOSS4G all took place consecutively, the schedule was shaping up to be extremely packed. We’d like to highlight some specific events and topics that you…

  • Access to safe abortion in Germany

    Our team thoroughly enjoyed the newly in-person State of the Map 2022 in Florence. We attended workshops, talks, and had the opportunity to present our own poster about the accessibility of abortion clinics in Germany, which will be discussed in this post and can be found here. In the following blog, we’ll explore more information…
