Koenig, K., Höfle, B., Hämmerle, M., Jarmer, T., Siegmann, B. & Lilienthal, H. (2015): Comparative classification analysis of post-harvest growth detection from terrestrial LiDAR point clouds in precision agriculture. ISPRS Journal of Photogrammetry and Remote Sensing. Vol. 104, pp. 112-125.

Within March 26-27, a COST ENERGIC meeting of working group 2 (WG2) on spatial data quality and infrastructures took place in Heidelberg. The COST ENERGIC stands for European Network Exploring Research into Geospatial Information Crowdsourcing: software and methodologies for harnessing geographic information from the crowd.

The meeting was hosted by GIScience research group. The meeting started by reviewing/presenting a set of research that has been recently carried out by the WG members and external guests. The meeting was further inspired by presentations given by Prof. Alexander Zipf, Adam Rousell, Hongchao Fan, Jamal Jokar, Maxim Rylov, Clemens Jacobs, Dr. Byron Antoniou (University College London), Flavio Lupia (National institute for agricultural economics, Italy), Prof. Ivan Chorbev (University of Skopje), Hristo Nikolov (Bulgarian Space agency). Some other WG members were not able to attend the meeting, therefore they were informed about the TO-DOs virtually and their points were mentioned and discussed in the meeting.

Furthermore, the content of the intended COST ENERGIC book on VGI was discussed and ideas for covering the whole topics were pointed out. The WG is organizing an ISSDQ special session on spatial data quality and an AGILE workshop called VALID-LAND.

Within our interdisciplinary collaborative research project MUSIEKE (Multidimensional Perceptibility of Cultural Heritage) the Jupiter Column (”Iupittergigantensäule”) of Ladenburg was scanned in 3D and in very high detail for the first time. Our colleagues from the IWR (FCGL Group of Hubert Mara) performed the measurement campaign.

In this report (in German) the SWR 4 radio station reports about the MUSIEKE 3D-scanning.

GIScience Heidelberg will now use the valuable 3D data to develop new tools for interactive web-based investigation and 3D visualization.

The photos were taken by Christian Seitz from the IWR.

The answer can be found in our most recent paper “Updating Digital Elevation Models via Change Detection and Fusion of Human and Remote Sensor Data in Urban Environments” that has just been finally released in the International Journal of Digital Earth.

We are happy to report that our task designed for the citizen science platform crowdcrafting.org was selected as their #ProjectOfTheWeek. This will help us to finish our experiment to derive information about sidewalks using Mapillary street level imagery with the support of the crowd very soon. Sidewalk information is an important resource for accessible route planning.

A full-time PostDoc position is available at the GIScience Research Group at the Department of Geography of Heidelberg University.
The aim is to contribute to the research at the GIScience Research Group and to start building an own junior research group including the mentoring of PhD students.
The candidate should have a demonstrated research track in at least one or more of the following topics:

- Conceputalization and Development of GI Algorithms and Methods
- GeoComputation and Spatial Data Mining
- GeoWeb, GI Services and Apps

We expect a PhD in either Computer Science, Geoinformatics, Geography or related fields, as well as strong and demonstrated research experience in Geoinformatics, paired with the ability for independent scientific work, management skills, the acquisition of third party funding as well as teamwork and leadership.

We offer an attractive job in an interdisciplinary dynamic team with excellent possibilities for research and further qualification. The GIScience Research Group is member in the Interdisciplinary Center for Scientific Computing (IWR), the Heidelberg Center for the Environment (HCE) and the Heidelberg Center for Cultural Heritage (HCCH). The University of Excellence Heidelberg belongs to the internationally top ranked universities and offers an especially stimulating research environment.

Please send the usual documents (full CV, grades, papers etc.) to Mrs. Bettina Knorr:
Bettina.knorr@geog.uni-heidelberg.de (Managing Assistant of Prof. Alexander Zipf)
– until April 22 2015. The position shall be filled as soon as possible. The initial duration of the contract is dependent on the experience of the candidate.

On friday 3/13, Melanie Eckle, Steffen John and Stefan Hahmann of the GIScience group Heidelberg were invited to a special event at Mannheim town hall. The city of Mannheim showed appreciation to the engagement of the GIScience group during the Open Data Day in Mannheim.

Melanie Eckle (distaster mappers Heidelberg) gave a presentation about the speed mapping session in the area of South Sudan which was performed during the Open Data Day. It was emphasized that the same mapping techniques that were applied during this event could also help if disasters, such as severe floodings or fires, happen in the Rhine-Neckar-Region.

Stefan Hahmann presented the outcomes of the Open Data Day that are relevant for the CAP4ACCESS project. These are the citizen science tool Crowdcrafting applied to the detection of sidewalks from Mapillary imagery and the extension of an OSM quality visualisation tool to show streets in OSM that do not have sidewalk information yet. Both of these applications emphasize the need of open data to support accessible route planning.

The first mayor of Mannheim was very impressed by the engagement of all of the involved hackers in the Open Data Day. Ideas raised by the developed applications were discussed and further support for similar events was announced. The city of Mannheim plans to start an Open Data portal by September 2015 where social data, geodata and election data shall be available under open data license.

The event was a great way to make some of the most important actors in our region aware of the advantages that Open Data has for the public. Many thanks goes to Oliver Rack from Open Data Rhine-Neckar for organizing the Open Data Day. All presented project were honored with 200€ each.

To learn more about the Mannheims Open Data initiatives, we recommend to watch the Open Data Day movie and the corresponding Rhein-Neckar-Fernsehen TV broadcast (both in German)!

Dear colleagues,

We are happy to inform you that the deadline for paper submission for almost all events at the ISPRS Geospatial Week 2015 is extended to 15 April 2015 in order to faclicitate a consistent logistics and because of several demands to extend the deadline.
This applies also to our session on Quality analysis of Volunteered Geographic Information (VGI) towards effective use at the 9th International Symposium on Spatial Data Quality (ISSDQ 2015), which will take place in Montpellier, France, from September 28th to October 3rd 2015. Please consider submitting and presenting your relevant research in the session. Here is the Call For Papers.

Bernhard represented the GIScience discipline in the Ladenburg Discourse of the Daimler and Benz Foundation on the “Digital Model” of the UNESCO World Heritage Site Lorsch Abbey, which took place 13-14 March 2015 in Ladenburg. The Ladenburg discourse was organized by Susanne Krömker from the IWR of the Heidelberg University.

The main aim of the scientific exchange and intensive discussions was to outline a concept for a holistic digital model of the abbey, which should include 3D datasets and visualization as well as historic and archaeological databases.

One year ago, the LiDAR Research Group Heidelberg (LRG) already performed a very detailed laser scan of the Kings Hall (Torhalle) in cooperation with Christian Seitz.

The GIScience group Heidelberg participated actively in the 2015 Annual Meeting of the DGPF (German Society for Photogrammetry, Remote Sensing and Geoinformation), which took place 16-18 March 2015 in Cologne.

Bernhard hold a keynote lecture on “LiDAR Point Cloud Information and Web Infrastructure for 3D Vegetation Analysis”, which was embedded in a special Workshop on Laser Scanning Applications. He presented the LVISA System, which can be explored online here: LVISA Web Portal.

Martin gave a talk on “Terrestrial and UAS-borne Imagery for Quarry Monitoring with Low-Cost Structure from Motion”. The abstract to the talk can be found in the online program.
