Therefore a prelimnary draft agenda of the workshop at AGILE 2018 in Lund has been posted. Looks like an interesting and promising programme! Stay tuned for further updates and join us for discussions and collaborative sessions in…

  • Associating OpenStreetMap tags to CORINE land-cover classes using text and semantic similarity measures

    With the aim of rapidly estimating the updated state of the CORINE land-cover map at the frequency with which the OpenStreetMap (OSM) dataset is edited and extended, we propose an approach for automatically associating widely used OSM tags to Level 1 and Level 2 CORINE land-cover classes. This association is probabilistic and is undertaken based…

  • Enhancing Crowdsourced Classification on Human Settlements Utilizing Logistic Regression Aggregation and Intrinsic Context Factors

    Among semi-automated methods and pre-processed data products, crowdsourcing is another tool which can help to collect information on human settlements and complement existing data, yet it’s accuracy is debated. Whereas the potential of crowdsourced datasets for training of machine learning algorithms has been explored recently, only few work has been done towards utilizing machine learning…

  • Routing for Accessibility – new Project with City of Heidelberg

    Accessibility is a widely discussed topic and there are a growing number of efforts to sensitise European cities and municipalities to the topic. A focus of such efforts is the facilitation of easy access to public places for everyone, including those with walking disabilities, balance and visual disorders, as well as people requiring the use…

  • Overview GIScience Colloquium Heidelberg SoSe 2018

Internationale Gäste berichten aus ihren interessanten Forschungsprojekten. Nutzen Sie die Gelegenheit, sich über die neuesten Entwicklungen in der Geoinformatik und in angrenzenden Forschungsfeldern zu informieren und mit Forschern aus aller Welt zu diskutieren! Das…

  • disastermappers heidelberg OSM Mapathons this semester

    as mentioned earlier this Monday will see the first of our disastermappers heidelberg Mapathons this summer semester. But this will definitely not be your only chance to participate in some collaborative OSM mapping or learning how to work with OSM data this semester at Heidelberg University. So here is the current schedule. This should help…

  • Talks at Heidelberg Center for the Environment (HCE) “Heidelberg Bridge” Colloquium SoSe 2018

    As a founding member of Heidelberg Center for the Environment (HCE) we want to share the dates for the HCE’s “Heidelberg Bridge” Colloquium series. This semester the Institute of Geography is involved with two presentations and one of these is from the GIScience group with Dr. Sven Lautenbach talking about his work on ecosystem services.…

  • The Ohsome API: dynamic OSM statistics for real-world applications

    The Ohsome API, developed at HeiGIT, is part of the ohsome OSM history analytics platform (and yes, it is pronounced like the word “awesome” 😉.  It serves as the connection between the OpenStreetMap History Database (OSHDB) and possible frontends, such as the Ohsome Nepal Dashboard prototype. The communication with the Ohsome API works via HTTP GET and POST requests as…

  • Apartment search with Openrouteservice; a new Python notebook example:

    As promised we offer some more examples on how to use Openrouteservice for some applications. In this notebook  example, we’d like to showcase one way to go about finding an apartment based on OSM data. We’ll using different openrouteservice API’s to help you look for an apartment. Here is the full example with code and…

  • Coupling maximum entropy modeling with geotagged social media data to determine the geographic distribution of tourists

    Modeling the geographic distribution of tourists at a tourist destination is crucial when it comes to enhancing the destination’s resilience to disasters and crises, as it enables the efficient allocation of limited resources to precise geographic locations. Seldom have existing studies explored the geographic distribution of tourists through understanding the mechanisms behind it. A recently…
