Workshop on Testing Geospatial Web Services / Persistent Testbed (PTB)

January 28th, 2011 @ 14:35 by Bastian Schäffer,
Posted in Communities, Geoprocessing

Call for Presentations (Deadline 1st March 2011)

The workshop is held to improve interoperability of open-source and
proprietary Geo Web Service software components. Therefore it is
important to outline the present state of the art of technical and to
identify scientific issues related to the field of Geo Web Services.
Further goals are the development of testing strategies/procedures and
the support of geospatial research in major EU programs and education.

The full day workshop will be held in context of the 14th AGILE
International Conference on Geographic Information Science in Utrecht,
The Netherlands, on 18th April 2011. As the AGILE/EuroSDR/OGC Persistent
SDI Testbed for Research and Teaching in Europe (PTB, is co-organizing the workshop, it will be shown
how different Testbed Collaboration could mutually benefit, how to
develop synergies and how to improve the sustainability of running
demonstrators for further work or research. Future strategies for
testing Geo Web Services will also be developed and discussed.

Workshop topics:

  • Scientific questions in the field of Geo Web Services
  • Geo Web Service Software tests
  • Different testing methods and testing strategies with a special focus on interoperability, compliance and performance
  • Different testbeds and testing activities (including PTB)
  • Former activities and demonstrators (including reports from current Phase 2 of the PTB) as well as testbeds related to INSPIRE, GMES etc.
  • Concerning technologies for developing testing facilities

The workshop consists of invited talks and presentations selected from
this call as well as of panel discussions about future testing
strategies and testbed development (including discussions about
strategies and testbed advances of the PTB). Please submit a short
abstract of your presentation (max 300 words) before 1st March. Based on
this abstracts the presentations will be selected through the organizing
committee. Presentations will be between 20 and 30 minutes (including
discussions). The deadline for the notification of acceptance is the
15th March 2011.

All presentations and abstracts will be published on the PTB website

Using SOS and WMS for Real-Time Ship Tracking

Recently 52°North has conducted a project together with the Information Technology Service Centre of the German Federal Ministry of Transport, Building and Urban Development at the Federal Waterways Engineering and Research Institute (DLZ-IT BMVBS). The goal was to analyse the feasibility of using Sensor Web Enablement (SWE) components for integrating near real-time ship tracking data into spatial data infrastructures.

The ship tracking data used in the project are gathered by the Automatic Information System (AIS). For making the AIS data accessible a customised version of the 52°North Sensor Observation Service (SOS) was developed that relies on an existing SOAP service as underlying data source. In addition, a Web Map Service (based on the OX-Framework) was built, that creates map visualisations based on the data available from the SOS.

In summary this project shows an interesting new type of Sensor Web application. Whereas most previous use cases were focusing on different kinds of time series data, this project demonstrates that the SWE technology can also be used for tracking moving objects like ships.

For more information about this project you may contact Simon Jirka at 52°North ( or Roman Klipp at DLZ-IT BMVBS (
