Integrating Semantic and Syntactic Descriptions to Chain Geographic Services
TLDR
This method facilitates the use of XML-based service description languages to build a geoservice-reuse architecture based on common ontologies and shared service descriptions. Expand
Future SDI - Impulses from Geoinformatics Research and IT Trends
TLDR
A conceptual view of the dynamics of both SDIs and the Geospatial Web is given, and a picture of the SDI of the future is presented, one which benefits from these developments, based on an analysis of geoinformatics research topics and current ICT trends. Expand
A Lightweight Approach for the Sensor Observation Service to Share Environmental Data across Europe
TLDR
A lightweight profile for the OGC Sensor Observation Service is provided that ensures the necessary interoperability for seamlessly integrating the environmental data provided by the EEA's member states and thus forms the foundation for the developed data exchange mechanisms. Expand
Enhancing Geo-Service Chaining through Deep Service Descriptions
We demonstrate the integrated use of semantic and syntactic service descriptions, called deep service descriptions, for service chaining by combining two prototypes: one that deals with geoserviceExpand
Distributed spatio-temporal modeling and simulation
TLDR
A Web-based distributed spatio-temporal interoperability architecture DALI integrating these initiatives is presented, with the long term goal of making standardized off-the-shelf GI and simulation services usable for highly specialized simulation and controlling applications. Expand
Semantic and syntactic service descriptions at work in geo service chaining
SUMMARY In this paper we demonstrate the integrated use of semantic and syntactic service descriptions for service chaining, by combining a prototype that deals with service discovery and abstractExpand
Quo Vadis SDI
TLDR
A user-centric and evolution-oriented understanding of spatial data infrastructures (SDI) is proposed as an alternative approach to contemporary SDI definitions and dynamic chaining of geographic information services, semantic interoperability of GI-services, the user need for spatial decision support services, as well as security and commercial marketing issues are considered.

What happens at 52N? an open source approach to education and research
TLDR
In late 2004, the free and open source software initiative 52°North was founded by the Institute for Geoinformatics at the University of Muenster and con terra GmbH in order to face the challenge of acquiring and analysis of geospatial data within open Geospatial Data Infrastructures. Expand
Knowledge bases in spatial data infrastructures : a new level of decision support
TLDR
An alerting framework is proposed, that make use of formalized knowledge which is applied to spatiotemporal measurement data provided by an SDI environment, which allows the integration of real time data into SDI. Expand
