  • Abschlussarbeiten: Wissensorte in der Stadt – Internationale Bauaustellung Heidelberg IBA

    Themen für Abschlussarbeiten (Master, Bachelor, Lehramt) // pot. Hiwi-Arbeit Wissen schafft Stadt /// Wissensorte in der Stadt Erleben der Wissensorte der Stadt in Raum & Zeit In der Abteilung Geoinformatik werden mehrere Themen für Abschlussarbeiten im Rahmen des IBA-Kandidaten-Projektes „Wissensorte in der Stadt“ vergeben. Diese können an verschiedene Niveaus (Bachelor, Master, Diplom, Lehramt) angepasst werden…

  • New project started: OpenFloodRiskMap

    Flood emergency planning is a challenging task for many municipalities throughout the world, and particularly in Europe. Not only because there is no common methodology on how to detect the critical infrastructure that must be taking into account in emergency plans, but as well because of the fact that the changing flood-risk situation requires constant…

  • Analyzing public transport flows from uncertain social media

    The growing number of mobile devices equipped with GPS sensors having broadband internet access, allow users to actively participate and create content through mobile applications and location based services. Whether users are uploading geotagged photos via Flickr or Instagram, checking in at a venue with Foursquare or commenting on a local event via Twitter. These…

  • GIScience at the GIScience

    Last week members of the GIScience Research Group were attending the Eight International Conference on Geographic Information Science in Vienna. Beside the interesting welcome note given by Andrew U. Frank and further follow-up keynote talks, the first conference day was opened up for full day workshops covering various topics of GIScience. Geographic Information Workshop In…

  • A practical algorithm for labelling areal features outside their boundaries

    One of the subtasks of automated map labelling that has received little attention so far is the labelling of areas. Geographic areas often are represented by concave polygons which pose severe limitations on straightforward solutions due to their great variety of shape, a fact worsened by the lack of measures for quantifying feature-label relationships. In…

  • DFG project on extracting emotions for urban research started

    Recently the new research project “Urban Emotions” has started. It is funded by the German Research Foundation (DFG) and aims at the development of a methodology to extract contextual emotional information for spatial planning based on real-time people-as-sensors and crowdsourcing approaches with social media. The spatial and social structures of a city and its underlying…

  • Co-Chair of Geoinformatics Working Group @ DGPF

    The Working Group of Geoinformatics of the German Society for Photogrammetry, Remote Sensing and Geoinformation (DGPF) is led by Prof. Jan-Hendrik Haunert from the University of Osnabrück. The working group deals with research questions related to Geo-Information Systems (GIS), such as the integration of GIS and image data, GIS analysis algorithms and geospatial data infrastructures.…

  • Summary of CAP4Access workshop in Heidelberg

    On the 12th and 13th of August 2014, the Smart Simulation Group led by Dr. Mohamed Bakillah of the GIScience Research Group at Heidelberg University organized and hosted an internal workshop for the CAP4Access project partners. The aim of this workshop was to present and discuss the activities, sharing of tasks, ongoing progress and issues…

  • Field experiment: deriving pedestrian sidewalk information using LIDAR technology

    On 11th of September, the second experiment for the CAP4Access project for Heidelberg pilot city was performed by Smart Simulation group (led by Mohamed Bakillah) with collaboration of LIDAR research group of Heidelberg University. Bernhard Höfle, Amin Mobasheri and Evelyn Schmitz participated in this fieldwork, using RIEGL VZ-400 laser scanning device in order to collect…

  • Stenomaps: A new visual encoding for thematic maps

    Administrative regions and attached statistical data are often simply displayed by the contentious choropleth technique. A recent research collaboration between researchers from the Technical University Eindhoven, City University London and the GIScience group at Heidelberg University successfully added a new arrow to the quiver of Geovisualisation techniques: The Stenomap. The stenomap comprises a series of…

  • Field experiment: a low-cost approach for deriving pedestrian sidewalk network data

    As a task for CAP4Access project, on Monday 11th of August, members of the Smart Simulation group (Mohamed Bakillah, Amin Mobasheri and Sarah Labusga) of GIScience at Heidelberg University performed a field experiment together with people with limited mobilities. Several GPS trackers (with different characteristics and predefined parameters for data collection) were installed on three wheelchairs and for a selected…

  • Approach for Push-Based Result Transmission with Asynchronous Geospatial Processing

    Geospatial analyses are increasingly being conducted in networked environments. In such cases, geographic analyses are carried out by leveraging ressources (including geospatial algorithms) on some remote server. A user might upload some dataset onto a server, triggers some geo-computation and awaits the results. Most of such web-based geo-processing services are implementing the so called “Web…
