The journal article “Geospatial Standards for Web-enabled Environmental Models” has been published on the International Journal of Spatial Data Infrastructures Research. This paper is a joint effort by ENVISION (George Athanasopoulos from the National & Kapodistrian University
of Athens, Patrick Maué from University of Münster) and UncertWeb (Christoph Stasch and Lydia Gerhartz, both from University of Münster). Here is the abstract:
Serving geographic information via standardized Web services has been widely accepted as a useful approach. Web-enabled environmental models simulating real-world phenomena are, however, rare. The models predict observations traditionally served by geospatial Web services compliant to well-defined standards. Using standardized Web services could support decoupling of models, comparison of similar models, and the automatic integration into existing geospatial workflows. Modeling experts face several open issues when migrating existing environmental computer models to the Web. The selection of the Web service interface depends on the input parameters required for the successful execution of the computer model. Losing control over the execution of the models, and consequently also the confidence in model results, can be addressed to a certain extent by using translucent and standardized workflow languages. Mechanisms and open problems for the implementation of geospatial Web service compositions are discussed. Two scenarios about oil spills and the exposure to air pollution illustrate the impact of unconfigured model parameters for standard-compliant spatial data clients.

More detailed versions of screencasts explaining how to use the ENVISION platform for the annotation, discovery, and composition of environmental Web services have been published on videolectures.net. Head over to the demonstrators section to see a description of all available screencasts, or go directly to our video page on videolectures. Thanks again to our partner IJS for setting this up.

Jens Ortmann and Henry Michels from IFGI won the Best Paper Award at the 14th AGILE International Conference on Geographic Information Science with their paper “Modelling Umwelten”. Our work within ENVISION about the specification of Events and their impact on activities was subject of this paper.

The following demonstrator video (also available here) wraps up some highlights of the first project year. Due to the strict time limits we were forced to put as much information as possible in these ten minutes. More detailed videos which give you a bit more time to understand what is going on are following in the next few weeks.
Update: we’ve hit the bandwidth limit on screencast.com. If it doesn’t work for you, you can also directly download the video here:

A new deliverable has been published on the ENVISION website.
Link to the PDF file:
D2.2 Environmental Semantic Web Portal Version 1 - Initial development and user guide
Executive Summary:
This deliverable reports on the first release of the ENVISION Portal. The ENVISION Portal allows the environmental community to use domain specific Web-Models or create new ones building upon the available resources. It is used by non ICT-Skilled users to produce websites dedicated to specific environmental scenarios, which embed web service compositions implementing environmental models. It is a generic solution to be used for different modelling domains and has to provide a community based system.
The first release of the ENVISION Portal provides:
- support of Community with authentication,
- resource management,
- an annotation mechanism,
- discovery of resources,
- a composition designer,
- a way to create new scenario websites,
- an access to dedicated websites.
This deliverable provides details on the aforementioned items and puts them in the context of the overall ENVISION architecture. The first release of the ENVISION Portal presented in this deliverable is functional and already available for internal use for the ENVISION consortium. Significant changes and improvements will be performed during the second and third years of the project and will be reported in the deliverable due for month 24 and month 34 of the project.
