News from the LODUM headquarters and all things Linked Open Data.

A linked data based web application will be presented as a student contribution by Friedrich Müller at the FOSSGIS Conference (11-13 March 2015) in Münster (  read the abstract ). The application shows dynamic geovisualizations of the exploration of cause-effect relationships between cancer types and environmental substances.

The paper entitled “Automated Generation of Indoor Accessibility Information for Mobility-Impaired Individuals” by Nemanja Kostic and Dr Simon Scheider has been accepted at the AGILE 2015 conference, taking place 9 – 12 June in Lisbon.  The paper proposes a methodology to automate the extraction of information on the accessibility of indoor spaces, starting with CAD floor plans.  Simulation of movement is used to compute the accessible space of an indoor environment by comparing the degree of match between geometrical demands of navigation in a wheelchair and the relevant physical properties of the environment.  The authors also investigate digital representations of indoor environments and adopt the grid graph model as suitable both for running simulations and for deriving higher-level networks of indoor places and their connections.  These can be used to communicate the results of the simulations to users of assistive navigation systems in a way that more closely resembles the ways humans conceive of and communicate about space.

How can linked data help to describe and search library media?
The articleContent and context description – How linked spatio-temporal data enables novel information services for libraries (Authors: Simon Scheider, Auriol Degbelo, Werner Kuhn, Holger Przibytzin) to appear in gis.Science takes a look at the question. It discusses the usefulness of linked spatio-temporal data for the realization of tasks such as the description, searching and analysis of media, and illustrates the ideas presented through examples from LODUM and related work.
Congrats to the authors!

Simon Scheider, Jim Jones, Alber Sánchez and Carsten Keßler won the best paper award for Encoding and Querying Historic Map Content presented last week at AGILE conference in Castellón, Spain. In the paper, the authors provide a formal means to encode Historic Map content. They also present a tool to georeference and enrich historic maps content using external sources.

Congratulations to all!





Little Steps Towards Big Goals. Using Linked Data to Develop Next Generation Spatial Data Infrastructures (aka SDI 3.0) is the title of our short paper to be presented this week at the AGILE Conference 2014 in Castelló, Spain.

This paper is the outcome of a collaboration between the LIFE team and the Polish research group on Geosemantic Web and Linked Open Geodata, WOGIS.

The authors illustrate the benefits and potential of the Linked Open Data and the Semantic Web approach to support and enrich SDI applications, and emphasize the use of the LOD4WFS Adapter. The LOD4WFS Adapter was proposed by Jones et al., 2014 and offers an alternative for multi-perspective GI applications, creating on-demand data sets based on multiple GI data sources, and exposing this information using the OGC WFS Standard.

We are happy to announce we have two full papers accepted for AGILE 2014:

  • Simon Scheider, Jim Jones, Alber Sanchez and Carsten Keßler: Encoding and querying historic map content. The paper suggests an approach to describe historic map content and ways to formally encode  historic map content, allows the formulation of queries based on semantic content in maps.

AGILE 2014, the 17th AGILE Conference on Geographic Information Science, will be held in Castellón (Spain) from June 3rd to June 6th 2014.

We’re involved in this year’s edition of the Linked Science workshop again, which has been accepted for ISWC 2013 in Sydney, Australia, in October. This year, we will focus on Supporting Reproducibility, Scientific Investigations and Experiments. The workshop page (which will be continually updated until the event) and the initial call for papers can be found here.
