  • Letzte Vorbereitungen: Start der MS Wissenschaft am 16. Mai 2019

    Mitmach-Exponate direkt aus der Forschung geben in der Ausstellung auf der MS Wissenschaft 2019 Einblicke in die Entwicklung und Anwendung Künstlicher Intelligenzen (KI). Die MS Wissenschaft startet ihre Tour am 16. Mai 2019 in Berlin und besucht Ende August auch Heidelberg. Das Exponat „Mensch Maschine – Forschung im Team“ zeigt wie Trainingsdaten für KI-Algorithmen erstellt…

  • How to become ohsome part 5: Measuring numbers of users editing different OSM features

    Besides dealing with a snake, making quality assessments, or generating comparable statistics, one needs to know how to handle the whole functionality provided by the ohsome API to really become ohsome. And to achieve exactly that, this blog presents the last missing entry point to the API from the current toolkit, namely the /users resource. With its help you can receive aggregated…

  • HeiGIT/GIScience at Global Platform for Disaster Risk Reduction and Multi Hazard Early Warning Conference

    Middle of May, Geneva becomes the gathering place for citizens, political leaders, government institutions, private sector, civil society, and scientific and technical institutions, that all jointly work towards a big objective – to manage disaster risk. In line with the Sendai Framework, the conference is focusing on and strengthening the shift from the management of…

  • Landcover monitoring with emphasis on vegetation under the climatic change pressure using multitemporal and multisource remote sensing data fusion

    The new project on landcover monitoring with emphasis on vegetation under the climatic change pressure using multitemporal and multisource remote sensing data is a collaboration project funded in the framework of 4EU+ Flagship 4: Biodiversity and Sustainable Developement with Markéta Potůčková (Department of Applied Geoinformatics and Cartography, Charles University Prague) as PI of the project.…

  • Projekt “TARDUR” startet: Open-Source-Routenplanung mit zeitabhängigen Beschränkungen

    Zeitabhängige Sperrungen und Nutzungsbeschränkungen von Straßen werden bislang in keiner frei verfügbaren Software zur Routenplanung genutzt. In dem im März gestarteten Projekt “TARDUR – Temporal Access Restrictions for Dynamic Ultra-Flexible Routing” gehen die Universität Heidelberg und die Firma GraphHopper dieses Problem an. Das Projekt wird im Rahmen der Förderrichtlinie Modernitätsfonds (“mFUND”) mit insgesamt 100.000 Euro…

  • meinGrün Umfrage: Wofür nutzen Sie städtische Grünflächen?

    Alle Jahre wieder blühen die Kirschbäume vor unserem Institutsgebäude in voller Pracht und laden Passanten allen Alters ein zum Verweilen. Städtische Grünflächen wie diese leisten einen wichtigen Beitrag zur urbanen Lebensqualität, indem sie viele Funktionen wie Naturerfahrung, sozialen Austausch und Erholung ermöglichen. Jedoch eignet sich nicht jeden Grünfläche gleichermaßen für jeden Einzelnen und jede Aktivität.…

  • Project “TARDUR” starts: Open-source routing with time-dependent restrictions

    Time-dependent restrictions and temporal road closures are so far not considered in any freely available software for route planning. Heidelberg University and the company GraphHopper aim to address this issue in their joint project “TARDUR – Temporal Access Restrictions for Dynamic Ultra-Flexible Routing”. The project started in March and is supported by the Federal Ministry…

  • OpenStreetMap History Database – version 0.5

    The OpenStreetMap History Database (OSHDB) is what powers most of the functionality of HeiGIT’s ohsome platform. The ohsome API for example, which was often showcased here in the blog, is built on top of the OSHDB. Just recently, an open access software article about the OSHDB was published. Check it out to find out more…

  • 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,…
