  • 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…

  • ohsomeHeX provides access to OSM feature history

    Did you ever wonder how your city was mapped over time, how geometries were changed and refined, how mistakes were added and corrected again? Then read on: ohsomeHex has a great new feature for you – the individual object’s zoom-in-history-view. To continue in providing valuable insights into the quality and development process of OpenStreetMap data, we…

  • Detecting OpenStreetMap missing buildings by transferring pre-trained deep neural networks

    Recently, a new research paper “Detecting OpenStreetMap missing buildings by transferring pre-trained deep neural networks” (Pisl, J., Li, H., Herfort, B., Lautenbach, S., Zipf, A. 2021) has been accepted at the the 24th AGILE conference 2021. The conference will take place virually on June 8 to 11, 2021. Accurate and complete geographic data of human…

  • The impact of recent gully filling practices on wheat yield at the Campiña landscape in Southern Spain

    The significance of gully filling practices on agricultural production has been only rarely evaluated in literature. In this study, a medium-sized catchment was selected, for being representative of the conventional farming practices on annual crops in the Campiña landscape in Southern Spain. During two wheat campaigns, an analysis of the spatial and temporal evolution of…

  • Deriving indicators for Points of Interest and analyzing mixed activities in urban areas

    We are pleased that our research paper “Deriving indicators for Points of Interest and analyzing mixed activities in urban areas” (Ullah, Lautenbach, Zipf 2021) has been accepted at the 12th International Symposium on the Digital Earth (ISDE) scheduled within the GI Week 2021 in Salzburg. The conference will take place from July 5th to July…

  • All countries of South and Southeast Asia now on Open Healthcare Access Map

    It’s been a little longer than a month since we published the Open Healthcare Access Map. Last week we rolled out all countries of Sub-Saharan Africa. Today all countries of South and Southeast Asia follow. The web application is available here: https://apps.heigit.org/healthcare_access/. To get a clearer understanding of healthcare infrastructure data in OpenStreetMap, please consult…

  • UndercoverEisAgenten – “UndercoverEisAgenten” – Enabling Citizen Scientists to Monitor Permafrost Degradation

    (English version below) Die Folgen des Klimawandels sind besonders stark in den höheren Breiten unseres Planeten zu spüren. Die Arktis erwärmt sich derzeit überdurchschnittlich schnell. Dies führt zum Auftauen von Permafrost (dauerhaft gefrorenen Böden) mit ernsthaften Konsequenzen für das arktische Ökosystem. Etwa ein Viertel der Landfläche in der Nördlichen Hemisphäre ist durch Permafrost gekennzeichnet. Darin…

  • SYSSIFOSS at EGU21 on 26 April

    From 19 to 30 April 2021, European researchers from the Earth, planetary and space sciences are gathering in the virtual European Geosciences Union (EGU) assembly. On Monday, 26 April, two SYSSIFOSS presentations will be opening the block “Point clouds for forestry applications” in session BG11 – Remote sensing for forest applications. Dr. Fabian E. Fassnacht…

  • geoEpi – new DFG research project on spatio-temporal epidemiology of emerging viruses

    A couple of viruses are of global interest with respect to human health and well-being. These pathogens include the novel coronavirus SARS-CoV-2, Dengue, Chikungunya, Yellow fever, Zika and Ebola. These viruses show interesting spatio-temporal dynamics. Improved understanding of the driving and moderating factors will help to cope with these pathogens. The recently funded new project…

  • All countries of Sub-Saharan Africa now in Open Healthcare Access Map

    Last month we started the Open Healthcare Access Map.  Initially, only a few countries were featured. Gradually, more countries and regions are now being added. Today we release all countries of Sub-Saharan Africa. 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…

  • Mapping Public Urban Green Spaces Based on OpenStreetMap and Sentinel-2 Imagery Using Belief Functions

    Public urban green spaces are important for the urban quality of life. Still, comprehensive open data sets on urban green spaces are not available for most cities. As open and globally available data sets, the potential of Sentinel-2 satellite imagery and OpenStreetMap (OSM) data for urban green space mapping is high but limited due to…
