Dr. Nicole Aeschbach (TdLab Geography) conceives and leads the “Students’ Workshop” within the framework of the “7th German-Japanese University Presidents’ Conference” of the HeKKSaGOn network on September 12 and 13, 2019 in Heidelberg. In this university consortium, Heidelberg University, the University of Göttingen and the Karlsruhe Institute of Technology have joined forces with three of Japan’s leading universities – Kyoto University, Osaka University and Tohoku University. The aims of the network are to expand cooperation in research and teaching, initiate joint research projects and graduate programs, and promote the exchange of students, doctoral students and scientists. A workshop for students with participants from all network universities is embedded in the conference of the presidents and the scientific working groups. 21 invited students from Japan and Germany work together with Nicole Aeschbach on current challenges in the context of sustainable development.

We would like to invite you to contribute actively to the DGPF Annual Conference 2020 (Jahrestagung) in Stuttgart. Deadline for abstract submissions (500-1500 words) is 31 October 2019.

Our Working Group for Geoinformatics is looking forward to recent research and workbench insights covering the full range of methods in geoinformatics. Go for it and submit your cool research methods and new results to DGPF Jahrestagung 2020.

Talented students with excellent thesis research can also apply for the prestigious Karl-Kraus-Nachwuchsförderpreis 2020.

See you in Stuttgart.

First of all, thanks to everybody who attended our ohsome lab on OpenStreetMap History Analysis at last weeks FOSS4G in Bucharest. Even though there were eleven (!) tracks running in parallel, and our lab was not in the same location as the program track, we had some interested participants. Their affiliation ranged from public institutions to phd and bachelor/master students. For those of you that want to get a look at the presented information and try out these ohsome examples yourself, we’ve combined all material and links in snippets within our GitLab. Here is a link to the first example: https://gitlab.gistools.geog.uni-heidelberg.de/snippets/23. The second example plus the full presentation is linked within that first example.

The conference itself was well organized and had a lot of participants (around 1100). In addition to the conference we had a great time at the social events. We’ve met old colleagues and got to know new people, which is a key aspect of why attending conferences is an important part of the business-, but also of the social and personal life. It would be great to meet some familiar faces again in about 2.5 weeks in Heidelberg at this years global HOT Summit and State of the Map conferences. Looking forward to see you!

Bis zum 01.09.2019 kann die Austellung auf der MS Wissenschaft zum Thema “Künstliche Intelligenz” in Heidelberg besucht werden. Wir waren da und sind begeistert!

Für die Ausstellung hat das HeiGIT gemeinsam mit dem Alfred-Wegener-Institut für Polar- und Meeresforschung in Potsdam das Mitmach-Exponat Mensch und Maschine – Forschung im Team entwickelt.

We’re happy to announce a new version of our QGIS Plugin ORS Tools. Additionally to the core services of giving easy access to our directions, isochrone and matrix API’s, the plugin now allows users to optimize their trips via a Traveling Salesman service.

The openrouteservice API’s included a Vehicle Routing Optimization Machine since quite a while, implementing the excellent Vroom library (© Verso) on our infrastructure. It allows users to plan fleet schedules in an optimal way, where multiple locations need to be visited in the optimal order by one or more vehicles.

This feature is finally implemented in our QGIS Plugin and is activated by the click of a button. It’s available for interactive routing as well as for batch routing using processing algorithms:

Before and after waypoint optimization

Before and after waypoint optimization

In normal mode it will only optimize over the waypoints between the first and the last, assuming the user knows the start and end locations. However, you can also choose to optimize the start or destination. Be aware, that each user only has a contingent of 50 optimization requests per day: https://openrouteservice.org/plans/.

Furthermore, ORS Tools has a few more improvements:

  • Improved GUI, allowing to properly setting up to 50 waypoints per route
  • Avoid countries option: Specifying numerical ORS Codes for countries from this list, they can be avoided
  • Elevation along the route is returned automatically, so now the output is LineStringZ
  • New batch routing algorithm allowing the input of MultiPoint geometries, where each Multipoint feature will be treated as one route
Finally, the Github repository has a new permanent home: https://github.com/GIScience/orstools-qgis-plugin.

Happy routing!

This week, the annual conference FOSS4G (Free and Open Source Software for Geospatial) is taking place in Bucharest, Romania. The conference is organized by The Open Source Geospatial Foundation (OSGeo) and attracts over 1000 professionals from industry and academia each year. The HeiGIT Big Spatial Data Team will present the ohsome platform and related tools such as the oshome API, the ohsome dashboard or the ohsomeHEX OSM History Explorer in a 90 minutes lab session.

Title: Analyzing the OpenStreetMap History with the ohsome Platform

Lab-Info: The ohsome platform https://ohsome.org allows to query the OpenStreetMap OSM history data on a global scale and hence to examine the data evolution and user contributions in a flexible way. Use cases of this platform are to explore OSM history data, to investigate, and to analyse the quality of OSM data by using intrinsic measures.

When: Wednesday, 28th of August 2:30 pm - 4:00 pm (EEST / UTC+3) Sessions Round 2

Where: Room 5, University of Bucharest

Related blog posts: Basically almost every post under the ohsome tag, especially part 1 and part 2 of the “how to become ohsome” series. We are looking forward to this special conference and to maybe see some familiar faces in our lab.

Ohsome is based on the oshdb (OpenStreetMap history database) as explained here:

The International Symposium on Platial Information Science PLATIAL’19 will be held this year at the University of Warwick in September 5-6. The programme has just been published and includes a paper from our research group about a systematic literature review about Place in the GIScience Community.

As the first PLATIAL’2018 symposium held in Heidelberg 2018 the symposium is funded and organized by the “VGIscience” SPP of the Germany Research Foundation (DFG), where our group has two running projects (one about VGI data quality and one improving spatial analysis in social media streams) and a third new accepted project (about Deep Learning with VGI and Remote Sensing imagery).

We are delighted to invite you to join a workshop on open-source routing with time-dependent restrictions, see http://giscienceblog.uni-hd.de/2019/04/17/project-tardur-starts-open-source-routing-with-time-dependent-restrictions/.

The workshop is taking place on Friday before the State of the Map conference, 20th September 2019 in Heidelberg. It is free of charge and will last from 9:00 to 16:00 with a lunch break in between. Detailed programme will be announced closer to the event date.

The workshop will give you the chance to get a behind the scenes view of routing with temporal road restrictions such as nightly driving bans for trucks, one-way streets alternating between the directions and winter barriers in mountains. Technical challenges will be discussed based on the open-source solutions from GraphHopper and OpenRouteService which both rely on the open-access OpenStreetMap road network. Apart from an introduction to the TARDUR project you will have the unique opportunity to present your work and get in touch with other people who are considering applying time-dependent constraints in their projects.

If this sounds interesting to you, please register until Friday, 6th September .

We are looking forward to seeing you in Heidelberg!

  • How do the dynamics of surface change on a rock glacier look like over an entire summer season?
  • And how is rockfall activity and storage and talus supply from the headwall of a rock glacier related to patterns of its movement?

These and other questions are currently investigated within the AHK-4D and Geomorph4D projects of the 3DGeo Group. Since June this year, regular visits to the rock glacier Äußeres Hochebenkar (Austria) have been undertaken for repeated LiDAR measurements. With the generated 3D time-series dataset we will develop automated change analysis techniques to approach open questions in rock glacier research.

Find more details on the project websites of AHK-4D and Geomorph4D and follow our updates on Twitter #AHK4D.
