  • Openrouteservice Developers Dashboard Revamped

    Over the past few months the openrouteservice team has worked on a new developers dashboard in order to make the registration and usage of the API more easy and accessible. Now the developers using the openrouteservice API will experience a more intuitive, responsive interface and with a more polished better look and feel to view…

  • Live from the Ötztal Alps (#3): Exploring high mountain 3D geoinformation

    On the last day of fieldwork in the rotmoos valley two groups (terrestrial laser scanning (TLS) and photogrammetry) set off to the rotmoos glacier again. A second TLS dataset was aqcuired which enables the students to perform a change detection or deformation analysis. The electrical resistivity tomography (ERT) group futher explored the pre-Quaternary relief in…

  • Live from the Ötztal Alps (#2): Exploring high mountain 3D geoinformation

    Today was the second day of field work in the Rotmoos valley in the Ötztal Alps for our 16 students. The hot sun challenged the data acquisition but the impressive landscape makes up for every effort. The terrestrial laser scanning group climbed up the valley flanks to acquire a high resolution point cloud from an…

  • New Jupyter Notebook: Analysis of Access to Health Care using OpenRouteService Isochrones API

    We published a new jupyter notebook which depicts how to use the OpenRouteService Isochrones API to analyse health care acessibility in Madagascar. In the case of a disaster (natural or man made), a country is not only affected by the intensity of the disaster but also by it’s own vulnerability to it. Countries have different…

  • Live from the Ötztal Alps (#1): Exploring high mountain 3D geoinformation

    As part of the practical field training “3D Geodatenerfassung im Hochgebirge (Ötztal)”, 29 July – 04 August, 16 students explore pyhsical geography in an impressive high-mountain environment in the Ötztal valley, Austria. With the help of terrestrial LiDAR, RTK GNSS, close range photogrammetry and electrical resistivity tomography (ERT), multi-source datasets will be captured for the…

  • Meet us at State of the Map 2018 Milan: Ohsome talks and workshop ahead!

    In a few days – THIS Saturday July, 29. – the State of the Map 2018 Conference in Milan will opening its doors with many interesting talks and workshops related to OpenStreetMap. HeiGIT and the GIScience Research Group at Heidelberg University will be there with several persons and give the following presentations and even a…

  • 3D WebGIS: From Visualization to Analysis. An Efficient Browser-Based 3D Line-of-Sight Analysis

    3D WebGIS systems have been mentioned in the literature almost since the beginning of the graphical web era in the late 1990s. The potential use of 3D WebGIS is linked to a wide range of scientific and application domains, such as planning, controlling, tracking or simulation in crisis management, military mission planning, urban information systems,…

  • EU Sentinel 2 osmlanduse.org fusion @ Toulouse Space show

    Another chapter in machine human fusion land use device narrative: new Sentinel 2 osmlanduse.org product results based on OpenStreetMap plus Sentinel 2 data plus Machine Learning were presented at ToulouseSpaceShow 2018 during a European Space Agency (ESA) Research and User Support (RUS) event. Stay tuned: The new product will soon be available for all EU…

  • HeiGIT/GIScience@FOSS4G 2018

    FOSS4G 2018 is only 42 days away and we are excited to present our Openrouteservice for Disaster Management there. Furthermore, we will provide insights on the potential of the ohsome platform for the HOT community. Check out the program for further details. We hope to see you in Dar es Salaam, Tanzania, August 27 –…

  • AGIT30 was ohsome (and awesome)

    Members of the HeiGIT team were presenting parts of our work at this years AGIT/GI_Forum conference in Salzburg, Austria (as already announced in a previous blogpost). Julian Bruns was presenting the results of a joint work with the KIT and his old employer, the FZI, which is published in the GI-Forum journal (English conference running in parallel to the…

  • Follow-up to study with mobile low-cost 3D camera crop height measurements

    The study “Mobile low-cost 3D camera maize crop height measurements under field conditions” (see the respective blog entry) is now available also as print version: The updated citation is: Hämmerle, M. & Höfle, B. (2018): Mobile low-cost 3D camera maize crop height measurements under field conditions. Precision Agriculture 19(4), pp. 630-647. doi: 10.1007/s11119-017-9544-3.

  • Continued capturing of an active rock glacier in 3D

    For the fourth consecutive year, the 3DGeo team acquired the rock glacier Äußeres Hochebenkar in the Austrian Ötztal by terrestrial laser scanning. This adds another point cloud to the multitemporal dataset to observe how the active rock glacier changes over the years. In an elevation over 2600 m a.s.l., the complex terrain on and around…
