  • Derivation of an OSM graph with TMC LCL traffic information to provide real time traffic services

    Increasing traffic, especially in urban areas, leads to more and more infrastructural bottlenecks and congestion inside transportation networks. The aim is therefore to use existing transport networks as efficiently as possible. Current traffic and incident reports from the Traffic Message Channel (TMC) are an important source of information to provide further services in the context…

  • GIScience HD @ CEBIT 2015: Specialized Routing Services with IBM and HDM-I

    Tour-Optimization in the Cloud in cooperation with IBM and Heidelberg Mobil International HDM-I the GIScience Research Group of Heidelberg University presents new approaches and solutions for specialized tour-optimization based on free and open geodata from OpenStreetMap and Cloud-based services in the in the “Cloud Area” at the CEBIT computer fair. These services enable software developers…

  • OpenStreetMap and Mapsurfer.NET help to search for missing people

    We know many examples when VGI data (e.g., OpenStreetMap, Wikimapia, etc.) help to cope with effects of various humanitarian disasters all over the world. The reason of using open crowd-sourced data is clear. The geographic data are available for free. If, for some reason, data are missing for a specific region, it is not a…

  • Two successfully completed PhDs @ GIScience HD

    Last week two colleagues successfully defended their PhDs within the GIScience Research Group at Heidelberg University. The first was the PhD thesis entitled “Exploring and Simulating Spatial Patterns of Urban Growth Using Data-driven and knowledge-based Approaches” by Mr. Hossein Shafeezadeh Moghaddam. The main focus was the development and evaluation of different spatiotemporal modeling strategies for…

  • Ravenstein-Förderpreis 2014 for automated map labelling

    Two our colleagues, Maxim Rylov and Andreas Reimer have received a Ravenstein Recognition award from the German Cartographic Society. Their work in automation of map lettering has been recognized by jury members as a compelling and relevant topic that is undoubtedly interesting to all who concerns oneself with digital cartography. Their considerable achievements are the…

  • 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…

  • 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…

  • 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…

  • Lettering Maps by considering Basemap Detail

    If you followed our previous posts (#1, #2) concerning high quality cartographic label placement, then this post is worthy of notice. Topographic maps are arguably one of the most information-dense, yet intuitively usable, graphical artifacts produced by mankind. Cartography as science and practice has developed and collected a wealth of design principles and techniques to…

  • up2date data for ORS: new OSM Data Update Workflow for OpenRouteService

    A new tool for processing and updating the street network data from OpenStreetMap (OSM), that is used in OpenRouteService.org (ORS) has been developed and tested over the last months. Now it has been deployed. Therefore the data used in ORS is now up2date again and can be updated more easily in an regular manner than…

  • Improving the Quality of Cartographic Labeling

    The lettering process, including assigning names to point features, is an essential part of map production. While there have been numerous and varied research efforts to automate point-feature label placement (PFLP), none of them seems to have taken into account the many well-established cartographic precepts for point-feature annotation used by human cartographers. As a result,…

  • Our OSM-based maps continue to advance in popularity

    Last year we announced about a significant update of our OSM-based maps provided by the web map tile service OpenMapSurfer. Since that time we made a big progress in improving the overall performance of the service, added a lot of missing map elements (e.g. archaeological sites, waterfalls, highway milestones, building entrances, etc.) and noticeably enhanced…
