  • Apartment search with Openrouteservice; a new Python notebook example:

    As promised we offer some more examples on how to use Openrouteservice for some applications. In this notebook  example, we’d like to showcase one way to go about finding an apartment based on OSM data. We’ll using different openrouteservice API’s to help you look for an apartment. Here is the full example with code and…

  • 4D-LiDAR Snow Cover Monitoring at the Highest Summit of Germany

    The all-new terrestrial laser scanner (TLS) of the 3DGeo group (Prof. Bernhard Höfle) has been set up at the Environmental Research Station Schneefernerhaus over one week (mid of April 2018) to capture a unique highly temporal time series of the melting and degrading snow cover during the April’s week with the warmest daily maximum temperatures…

  • Coupling maximum entropy modeling with geotagged social media data to determine the geographic distribution of tourists

    Modeling the geographic distribution of tourists at a tourist destination is crucial when it comes to enhancing the destination’s resilience to disasters and crises, as it enables the efficient allocation of limited resources to precise geographic locations. Seldom have existing studies explored the geographic distribution of tourists through understanding the mechanisms behind it. A recently…

  • First prize of the GISRUK data challenge

    A team around Prof. Joao Porto de Albuquerque, including our GIScience Heidelberg colleague René Westerholt, has won this years GISRUK data challenge. Big Congratulations! The theme of the data challenge was to find novel and explicitly spatial insights on the Brexit. Our contribution relates the recent influx of foreign people to the Brexit voting outcomes.…

  • A taxonomy of quality assessment methods for volunteered and crowdsourced geographic information

    The growing use of crowdsourced geographic information (CGI) has prompted the employment of several methods for assessing information quality, which are aimed at addressing concerns on the lack of quality of the information provided by non‐experts. In a recently published work, we propose a taxonomy of methods for assessing the quality of CGI when no…

  • R package for Openrouteservice released!

    Great news for all enthusiasts of R stats – the popular open source stats system: the HeiGIT ORS team has developed a package to facilitate querying the openrouteservice API from R. It allows you to painlessly consume the following services: directions (routing) geocode isochrones (accessibilty) time-distace matrix pois (points of interest) You do not have to fiddle with processing…

  • Upcoming Ohsome Conferences

    The Ohsome OSM history analytics platform, developed at HeiGIT, will be presented at the following conferences: ISCRAM in Rochester, NY, USA (20th – 23rd of May) In the short paper for the International Conference for Information Systems for Crisis Response and Management we illustrate the specific potential of the ohsome platform for disaster activations by means of two…

  • Colloquium on Micro Diagrams for Geovisual Analysis of Point Datasets

    We cordially invite everybody interested to our next open GIScience colloquium talk The speaker is Mathias Gröbe Technical University of Dresden, Department of Geosciences, Institute of Cartography When: Monday 23.04.2018, 14:15 Where: INF 348, room 015 (Institute of Geography, Heidelberg University) Micro Diagrams: A Multi-Scale Approach for Geovisual Analysis of Categorised Point Datasets Location-based social media from…

  • Heidelberg Geography in Blossom

    Again and again each spring it is really awesome (not ohsome 😉 to have a look at our GIScience offices at the Institute of Geography, INF 348, Heidelberg University.

  • International PhD Defenses in 3DGeo Research

    We would like to congratulate Dr. Milutin Milenkovic (Vienna Univ. of Technology, AT) and Dr. Xi Zhu (ITC, NL) for achieving their PhD degree in the domain of 3DGeo research utilizing point clouds from LiDAR and photogrammetry. Bernhard Höfle joined the defenses of the two very good PhD studies: Xi Zhu (2018): Forest Leaf Water…

  • A brief intro to the OpenStreetMap History Database (OSHDB) API

    The OpenStreetMap History Database (OSHDB) is the main data backend developed at HeiGIT for the ohsome OSM history analytics platform, that will make OSM’s history data more accessible for further analysis. OpenStreetMap (OSM) is a rich resource of freely available geographic information. However, the possibilities for analyzing OSM data on a global scale are limited because of…

  • Open – POI – Service Helps You Find Points of Interest!

    Once again we are extremely excited to announce a new open source project we have been working on over the past few months. To honor the name, we have coined it openpoiservice and it has the simple task of finding points of interest for a given geometry! To this end, it is able to return…
