- KonferenzbeitragA Sensor and Semantic Data Warehouse for Integrated Water Resource Management(Proceedings of the 28th Conference on Environmental Informatics - Informatics for Environmental Protection, Sustainable Development and Risk Management, 2014) Abecker, Andreas; Brauer, Torsten; Magoutas, Babis; Mentzas, Gregoris; Papageorgiou, Nikos; Quenzer, MichaelThe goal of the EU-FP7 project WatERP is to achieve more interoperability of software systems along the water-supply chain. A central element to achieve that is the WatERP Water Data Warehouse which shall act as a central data-exchange platform between different software systems. The WDW shall be able to store and provide sensor, measurement and forecasting data, as well as semantic knowledge about the water-supply chain. It shall be as standards-compliant as reasonable and shall offer query and reasoning facilities over sensor data, spatial information and ontological knowledge. In this paper, we show the basic architecture of the WDW and shortly discuss its main design decisions.
- KonferenzbeitragAktuelle Weiterentwicklungen von Cadenza Mobile für das mobile Arbeiten mit Geodaten in der öffentlichen Verwaltung(Environmental Infomatics - Stability, Continuity, Innovation: Current trends and future perspectives based on 30 years of history, 2016) Lübke, Jens; Terzic, Boris; Abecker, Andreas; Hofmann, Claus; Kazakos, Wassilios
- KonferenzbeitragIntegrating Semantic Search for Relational Data into Environmental Information Systems(Innovations in Sharing Environmental Observations and Information, 2011) Abecker, Andreas; Bügel, Ulrich; Ebel, Renate; Schlachter, ThorstenIn this paper we briefly discuss two system prototypes that have been developed to improve search for environmental information through semantic technologies. While the HIPPOLYTOS prototype extends a specific, commercial data warehousing and spatial reporting system – disy CADENZA – in order to make search for structured, relational data easier, the SUI system implements a semantics-enabled search-broker approach for simultaneously accessing manifold different target information systems in a comprehensive environmental information portal. Finally, we sketch the envisioned integration of HIPPOLYTOS as one such SUI target system.
- KonferenzbeitragLatest Developments of the Linked Thesaurus Framework for the Environment (LusTRE)(EnviroInfo & ICT4S, Adjunct Proceedings, 2015) Abecker, Andreas; Schnitter, Karsten; Wössner, Roman; Albertoni, Riccardo; de Martino , Monica; Podestà, PaolaWe present a solution for inter-linking domain thesauri and other controlled vocabularies represented as Linked Data content within the LusTRE framework. We discuss how such inter-linked content can help users to easier and better express and use thesauri and controlled vocabularies for metadata work within Spatial Data Infrastructures, at the concrete example of an INSPIRE-driven environmental use case. We present the Thesaurus Exploi-tation services designed and implemented for LusTRE and their inte-gration with existing metadata editors and SDI geoportals.
- KonferenzbeitragMethods and Tools for More Efficient Working With OGC Web Processing Services(EnviroInfo & ICT4S, Adjunct Proceedings, 2015) Abecker, Andreas; Wössner, Roman; Alcacer-Labrador, Dorian; Bensmann, Felix; Roosmann, RainerWe start with the observation that the OGC Web Processing Service (WPS) is by far less widespread in public administrations than the OGC download and visualization services WMS, WFS, WCS. Based on this observation, it was the goal of the RichWPS research project to develop methods and tool which should facilitate the use of WPS in practice. Now, after the end of the RichWPS project, we briefly review most of its methodological and technological outcomes and try to conclude to which extent the project goals have been achieved.
- KonferenzbeitragParticipatory Sensing for Nature Conservation and Environment Protection(EnviroInfo Dessau 2012, Part 1: Core Application Areas, 2012) Abecker, Andreas; Braun, Simone; Kazakos, Wassilios; Zacharias, ValentinIn this paper, we introduce and define the concept of Participatory Sensing (PS), we collect a number of PS applications from the area of environment protection and nature conservation, we sketch the building blocks of a generic software architecture for PS, and we report on the implementation approach and the current status of the PartSense project which aims at providing reference solutions for professional PS applications.
- KonferenzbeitragTowards a Middleware for Data Management in Support of Open Government Data(Proceedings of the 27th Conference on Environmental Informatics - Informatics for Environmental Protection, Sustainable Development and Risk Management, 2013) Abecker, Andreas; Heidmann, Carsten; Hofmann, Claus; Kazakos, WassiliosCitizens demand it and politicians support it: Hence, the pressure to realize Open Governmental Data (OGD) projects is growing for public administrations and governments. Many pilot projects have already been started or are under way, though regulatory and organizational foundations are not yet mature enough in all respects. But even if all nontechnical questions will be answered, it still remains unclear how to set up a sustainable and economically reasonable software support for the OGD realization not for the one-shot set-up of an Open Data portal, but for its continuous running over a longer period of time, well embedded into existing technical and non-technical infrastructures. The widespread research and open source solutions for Open Data here mostly support only the very last steps of the OGD governance and publishing workflow, namely realization of a portal. In this paper, we suggest an approach how to use an existing data management infrastructure for all the early steps, including data collection, selection, harmonization, transformation and export in different formats, including metadata. To this end, we suggest to employ a suitably extended version of the disy Cadenza professional software for administration-internal spatial data management and reporting which is, up-to-date, mostly in use in German and Austrian environmental agencies.
- KonferenzbeitragTowards an Information System for Early Warning of Landslides(Environmental Informatics and Industrial Ecology, 2008) Breunig, Martin; Ortlieb, Eva; Mäs, Stephan; Boley, Conrad; Trauner, Franz-Xaver; Wiesel, Joachim; Richter, Daniela; Abecker, Andreas; Gallus, Dominik; Kazakos, Wassilios; Bartels, Andreas; Broscheit, Björn; Reinhardt, WolfgangMore than four million people lost their lives in disastrous geological events such as earth quakes, tsunamis and strong rainfall combined with landslides during the last century. Obviously there is a strong demand for analyzing such events and for developing early warning systems to save lives and properties. The European GIS community is invoked to provide its knowledge for the development of new information systems for early warning of geological events. However, at present the analysis and information preparation are still particularly critical points of the early warning chain. Furthermore, the responsible decision makers are usually confronted with huge amounts of structured and unstructured data. Thus the question is how they can be provided with a reliable and manageable amount of information to create the warning decision and for taking preventive measures. In this paper the objectives and requirements of the joint project “Development of suitable information systems for early warning systems” are presented, examining methods of an information system for the early recognition of geological hazards in a mass movement scenario. In the project the simulation of landslides is executed on the basis of geotechnical, mechanically founded models. Thus a better understanding of the geological processes can be achieved. Furthermore, the improvement of the information analysis and preparation are investigated. Therefore techniques such as GIS, numerical simulations, spatial data mining, geo-databases and linguistic methods are combined with each other.
- KonferenzbeitragUsing Interlinked Thesauri for INSPIRE-Compliant Metadata Management(Proceedings of the 28th Conference on Environmental Informatics - Informatics for Environmental Protection, Sustainable Development and Risk Management, 2014) Abecker, Andreas; Albertoni, Riccardo; Heidmann, Carsten; De Martino, Monica; Wössner, RomanAs part of the eENVplus project about infrastructures for the INSPIRE implementation, a Thesaurus Framework (LusTRE) is being developed which allows to interlink different environmental domain thesauri and offers access to them as one virtual integrated linked data source – which shall support better metadata compilation and metadata discovery for describing and finding INSPIRE data and services. Further, a Web Service infrastructure is being provided (the LusTRE Exploitation Services, LusTRE-ES) that allows to make optimum use of the knowledge contained in LusTRE for improving existing metadata tools. In this paper, we give an overview of LusTRE and present important aspects of the LusTRE-ES: its architecture and design principles, the REST interface, the list of services / service modules under development, and the way how these services shall improve existing metadata tools.
