  • Twitter as an indicator for whereabouts of people? Correlating Twitter with UK census data

    Detailed knowledge regarding the whereabouts of people and their social activities in urban areas with high spatial and temporal resolution is still widely unexplored. Thus, the spatiotemporal analysis of Location Based Social Networks (LBSN) has great potential regarding the ability to sense spatial processes and to gain knowledge about urban dynamics, especially with respect to…

  • Talk on OpenStreetMap data quality at University of São Paulo, Brazil

    During mid August and September, Amin Mobasheri had a short research visit to Institute of Mathematics and Computer Science (ICMC) at University of São Paulo, Brazil. Last week on 14th of September, he gave a presentation about “Open Geospatial Data Quality Assessment and Enrichment. The Case study of Routing and navigation services for people with limited…

  • Best Paper at ACM SIGSPATIAL GeoCrowd Workshop for our paper on Transport Flow Analysis from Social Media Data

    Our paper titled “Explorative Public Transport Flow Analysis from Uncertain Social Media Data” in the GeoCrowd 2014 workshop of the ACM SIGSPATIAL conference has been selected by the workshop organizers as its best paper. In this paper, we propose a framework to detect human mobility transportation hubs and infer public transport flows from unstructured georeferenced…

  • Missing Maps like Microtasking with PyBossa

    Benjamin (active Heidelberg disastermapper and GIScience group member) explains in this blog post how to create your own Missing Map like microtasking application using PyBossa An example is the microtasking app he did set up to identify human settlements and roads in South Kivu for the missing maps project at http://crowdmap.geog.uni-heidelberg.de/app/missing_maps_follow_up/. You can easily contribute…

  • Second expedition in the Mackenzie Delta

    Mid of August we started for our second field trip in the Canadian Arctic. This time the team consisted of Inga Beck, Sabrina Marx and Detlef May. As Sabrina already joined the trip in June, many things – such as customs, security etc. worked much easier than in June. We only had very little time…

  • Who is using OpenMapSurfer’s maps?

    In a previous blog post, we have imparted to our readers that OpenMapSurfer web map tile service is being used by several projects. Today, we want to provide an updated list of the users. Among them are e.g.: Garmin, the world leader in Global Positioning System (GPS) technology – careers.garmin.com/en-US Weather forecast web sites –…

  • Report on the 27th International Cartographic Conference; Rio de Janeiro, Brazil

    The 27th International Cartographic Conference (ICC) was held from 23-28th of August in Rio de Janeiro, Brazil. The conference brought together several hundreds of professors, researchers and students worldwide in three main disciplines of Cartography, GIScience, and Remote Sensing to discuss various research topics ranging from map design, map use, users and usabilities to location…

  • GIScience HD @ Intergeo

    In addition to our previously announced presentation, the GIScience group Heidelberg is also represented with a stand at the Intergeo. We present a variety of outcomes of our efforts from throughout the last years. These include, among others, spatial media analysis, OSM.3D and our highly recognized OpenRouteService or OpenMapSurfer.. Our stand is part of the…

    The Heidelberg University reports in a current press release (in German) about our new project 4DEMON: 4D Near Real-Time Environmental Monitoring, which is funded by the highly competitive Junior Professorship Funding Scheme of the Ministry of Science, Research and Arts, Baden-Wuerttemberg.

  • GIScience excursion to European Space Agency (ESA)

    Recently the GIScience Research Group at Heidelberg University visited the European Space Operations Centre (ESOC) in Darmstadt, Germany, which serves as the main mission control centre for the European Space Agency (ESA) . The Centre is responsible for a range of activities and in particular operating planetary and solar missions, such as Mars Express and…

  • Recent Progress in Automated Cartography at German Cartographers Day at INTERGEO

    The German Cartographers Day (Deutscher Kartographentag) is taking place at INTERGEO conference held in Stuttgart this week. We will present an update on recent progress in automated cartography in a talk by Andreas Reimer and Maxim Rylov about our latest improvements in automated label placement, which have been implemented in MapSurfer.NET as published as in OpenMapSurfer.uni-hd.de.…

  • Systematic review of current efforts to quantify the impacts of climate change on undernutrition

    Malnutrition is a challenge to the health and productivity of populations and is viewed as one of the five largest adverse health impacts of climate change. Nonetheless, systematic evidence quantifying these impacts is currently limited. Our aim was to assess the scientific evidence base for the impact of climate change on childhood undernutrition (particularly stunting)…
