  • Prize for best PhD for Rene Westerholt “Förderpreis Runder Tisch GIS München”

    Recently our former team member Rene Westerholt (now at Warwick UK) received this years prize for the best PhD at “Förderpreis Runder Tisch GIS München 2019“. The PhD was done in Heidelberg within the graduate school “CrowdAnalyser – Spatio-temporal Analysis of User-generated Content”.  We concratulate cordially! The following papers are part of the cummulative PhD…

  • STAP19 Workshop and Compact Course Concluded

    From 01-04 April 2019, the 3DGeo and FCGL research groups organized STAP19, a compact course and workshop on Spatial and Temporal Analysis of Geographic Phenomena at the Interdisciplinary Center for Scientific Computing (IWR, Heidelberg University). In a mix of lectures, invited talks and hands-on sessions, the participants learned about processing and analysis of 3D geodata,…

  • The New York Times + openrouteservice

    In a recent article by the NYTimes the openrouteservice API isochrones interface was consumed to derive regions of reachability from subway stations in New York City. Their findings show that two-thirds of 550.000 residents who have difficulty walking live far from an accessible subway station. Head over to this very interesting analysis which you can find…

  • Multi-Parameter Relief Map from High-Resolution DEMs: A Case Study of Mudstone Badland

    Topographic parameters of high-resolution digital elevation models (DEMs) with meter to sub-meter spatial resolution, such as slope, curvature, openness, and wetness index, show the spatial properties and surface characterizations of terrains. The multi-parameter relief map, including two-parameter (2P) or three-parameter (3P) information, can visualize the topographic slope and terrain concavities and convexities in the hue,…

  • Kick-off meeting of BMBF/MOST project “ER3DS” at Heidelberg University

    On Tuesday 26 March 2019, the 3DGeo Research Group of Prof. Bernhard Höfle and the newly founded Transdisciplinary Lab (TdLab) Geography (Dr. Nicole Aeschbach) hosted a workshop on “Emission Reduction in Smart Cities Using 3D Spatial Sensing and Analysis (ER3DS)” within the frame of the collaboration and exchange project ER3DS running from 2019 to 2020. The…

  • How to become ohsome part 4: handling a snake in a notebook on another planet

    Welcome back to a new episode of how to become ohsome. Yes, you’ve read the heading correctly. We are really talking about a snake in a notebook on another planet. If you are familiar with one of the most used programming languages in the GIS world, you might already know by now which snake is…

  • openrouteservice for Disaster Management: Response to Cyclone Idai

    The Humanitarian OpenStreetMap Team (HOT) has launched an activation to support humanitarian operations responding to the impact of Cyclone Idai. These efforts were already supported by more than 1500 mappers of the global OpenStreetMap (OSM) community that contribute geodata about the affected regions in Mozambique and the surrounding countries. The team at HeiGIT (Heidelberg Institute for…

  • HeiGIT supports Citizien Science @ Helmholtz ThinkCamp

    We are always happy to support citizen science projects at the HeiGIT. HeiGIT/ GIScience efforts already range from tools that assess the data quality of citizen science projects (see, e.g., this blog post about “Plausible Parrots“) to approaches related to data creation, like MapSwipe Analytics (learn more here). Currently, we are supporting citizen science approaches…

  • Multisource and Multitemporal Data Fusion in Remote Sensing: A Comprehensive Review of the State of the Art

    The recent, sharp increase in the availability of data captured by different sensors, combined with their considerable heterogeneity, poses a serious challenge for the effective and efficient processing of remotely sensed data. Such an increase in remote sensing and ancillary data sets, however, opens up the possibility of utilizing multimodal data sets in a joint…

  • Preview: Spatial Joins using the OpenStreetMap History Database OSHDB

    Max is two and loves spending Monday afternoons with his Dad at the playground. Finding a suitable playground however isn’t easy, since a few criteria must be met: there should be a bench and some trees nearby to get shelter from the sun and an ice cream shop within the neighbourhood. Using the new spatial…

  • Global analyses are ohsome

    We, the Big Spatial Data Analytics Group at HeiGIT have ohsome news to share: From now on, you can send your requests to our global ohsome API instance. So far, we’ve had a public instance for Nepal and Germany, but now you can analyse OSM’s history globally. Additionally to the API, we also have a global dashboard instance. You choose any…

  • Neues mFUND Project: Temporal Access Restrictions for Dynamic Ultra-Flexible Routing – TARDUR

    Problemstellung Bis dato wird eine wichtige Eigenschaft infrastruktureller Straßennetzdaten wie OSM in noch keiner frei verfügbaren Routing Anwendung voll ausgenutzt: zeitliche Restriktionen auf Straßen und Wegen, wie etwa tageszeit- oder saisonale Fahrbahnbeschränkungen. Dies ist unter anderem für Transport-Logistik-Firmen für ein effizientes Flottenmanagement (z.B. zeitlich variable Fahrverbote für Lastkraftwagen) von Bedeutung, aber auch im Hinblick auf eine…
