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…

  • Two-part Mapathons for better new user retention?

    The project “25 Mapathons“ goes into the next phase. Based on the experience of until today 17 OSM mapathons with German Red Cross (GRC) chapter and an extensive literature review on the success of mapathons, the “25 Mapathons” team has identified several points of possible improvement in the way how mapathons are conducted in general:…

  • Towards a framework for the analysis of local OSM contributions

    Volunteered Geographic  Information (VGI) such as OpenStreetMap (OSM) is often defined as the collaborative acquisition of geographic information and local knowledge by volunteers, amateurs or professionals (Goodchild, 2007). The increasing availability and importance of local data in OSM is largely acknowledged in VGI projects. Local knowledge provides access to a plethora of contextual information and…

  • HELIOS++ v1.0.6 released

    We are proud to present the newest HELIOS++ release, v1.0.6, with numerous bugfixes and support for the unique LiVOX scan pattern (using Risley prisms – the color indicates point indices and increases from blue to red): Furthermore, the Easter bunny left some Easter eggs in the ‘toyblocks’ scene: You can find the changlelog for the…

  • HeiGIT und DRK veröffentlichen weiteres Trainingsmaterial zu Mapathons 

    Gemeinsam mit dem Deutschen Roten Kreuz (DRK) hat das HeiGIT heute das Dokument “Die häufigsten Fehler beim „mappen“ mit dem iD-Editor & deren Lösung” veröffentlicht. Das Dokument ist komplementär zum Handbuch zur Veranstaltung von Mapathons, welches bereits 2020 veröffentlicht wurde. Das neue Dokument beschreibt kurz und bündig häufig auftretende Fehler beim Mappen und soll so noch unerfahrenen Mapper*innen…

  • German Mass Vaccination Sites in Open Healthcare Access Map

    Last week we introduced Open Healthcare Access Map. Our new web application for interactively sharing results of accessibility estimates based on OpenStreetMap healthcare facilities and openrouteservice isochrones. A new update now shows motorized accessibility estimates of mass vaccination sites in Germany. Accessible via this directlink: https://apps.heigit.org/healthcare_access/#/countries/deu/covid19_vaccination/adm0 These results are based on an analysis by Sven…

  • Talk: Deep Learning for Point Cloud Processing

    Lukas Winiwarter of the 3DGeo group was invited by the Austrian Society of Surveying and Geoinformation (OVG) to give a talk on the application of deep learning on point clouds, which took place on March 24. In his talk, Lukas presented four different state-of-the-art approaches to consider the irregular, unordered structure of point clouds, which…
