  • 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…

  • The Chilean newspaper El Mercurio reports about our VGI research

    The Chilean newspaper El Mercurio has released an article about Heidelberg’s research on VGI and Neogeography in their Science and Technology section in the issue of 14 July 2014. El Mercurio, Santiago de Chile (No. 41.265), p. A11: Neogeografía: La geografía evoluciona al alero de las redes sociales.

  • 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…

  • GIScience Heidelberg @ Santiago de Chile

    The Heidelberg Center for Latin America (HCLA) in Santiago de Chile offers a Master of Science in Governance of Risk and Resources. This cooperative venture between the Geography institutes of Heidelberg University, the Universidad Catolica de Chile and the Universidad de Chile focuses on the (political and economic) controllability of problem-driven interaction between humans and…

Further information can be found here: – Job posting: Research Associate in Social Science / Humanities

  • 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,…

  • New Academy Project on Interdisciplinary Neogeography in Natural Hazard Analysis in Chile

    The research project NEOHAZ – NEOgeography of a Digital Earth: Geoinformation Science as Methodological Bridge in Interdisciplinary Natural HAZard Analysis is funded by the WIN-Kolleg of the Heidelberg Academy of Sciences and Humanities (HAW) and runs from 2014 till 2017. Project Description: The understanding of complex human-environment interactions via measuring and observing can only be…

  • Exploiting Big VGI to Improve Routing and Navigation Services

    Due to development of communication technologies, the amount of data, which each organization has to deal with, has been rapidly growing. The huge volumes of data appear as an opportunity to improve the performance and reliability of various applications, as such routing and navigation services can be named. However, the analysis of large datasets, commonly…

  • Fusion of human and remote sensor data in urban environments

    OpenStreetMap (OSM) currently represents the most popular project of Volunteered Geographic Information (VGI): geodata are collected by common people and made available for public use. Airborne Laser Scanning (ALS) enables the acquisition of high-resolution digital elevation models that are used for many applications. Our new study combines the advantages of both ALS and OSM, offering…

  • AGILE Workshop on Digital Earth: What the hack?

    We invite you to participate in our workshop Digital Earth: What the hack?, as part of the 17th AGILE Conference on Geographic Information Science, 3-6 June 2014, Castellón, Spain. The proposed workshop will prepare hackathons including geospatial information and processing across a variety of possible disciplines and thereby implementing Digital Earth applications. Hackathons are a…

  • More than 100 Million Buildings in OpenStreetMap

    and therefore also in OSM-3D.org. Just before Christmas the number of building footprints hit the magical number of 100.000.000. “Building” has been for some time now the most frequently used tag defining a map feature in OpenStreetMap. We use the building footprints from OSM to generate an automatically updated special database of 3D buildings displayed…

  • Digital Earth Science Forum “Digital Earth Innovations” at the University of Osnabrueck starts European cooperation

    The International Digital Earth Science Forum organized by Institute for Geoinformatics and Remote Sensing (IGF), the Youth Commission of the International Society for Digital Earth (ISDE) and the Association for the Promotion of Geoinformatics in Nothern Germany (GiN e.V.) took place on 4th of December 2013 at the University of Osnabrueck inside the botanical garden.…
