GET participated at the reconstruction and the development of the new www.geodata.gov.gr application as part of the research project PublicaMindi. The projects has been successfully completed and funded by the 7th Framework Program. Our partners in this project are:
- Institute for the Management of Information Systems of the “Athena” Research and Innovation Centre in Information, Communication and Knowledge Technologies
Basic objectives of the project were:
- Extension of open data catalogues for integrated publishing support, geospatial data lifecycle diligence and management,
- Tools development and integration permitting multilinguality interconnection and management regarding geospatial data in cross-borders framework
- Scalable/expandable technologies and services for on-demand creation and reuse of maps with the use of open geospatial data
- Analysis services development for the accurate control of open geospatial data use, scalable/expandable technologies and reusable data APIs development for querries support and open geospatial data editing and analysis.
The development of the project was based exclusively on Free and Open Source Software and the architecture is presented below.
GET participated at the research project “City Water Management Systems and Water Distribution Network Monitoring – AquaNet” (code 11ΣΥΝ_6_925) of the General Secretariat for Research and Technology under the framework “Cooperation 2011 – Partnerships of Production and Research Institutions in Focused Research and Technology Sectors” of the Operational Programme “COMPETITIVENESS AND ENTREPRENEURSHIP”.
Our partners for this project were:
- Telecommunications Systems Institute (TSI) of Technical University of Crete ( TUC)
- Radiocommunications Laboratory (RCL) of Physics department of Aristotle University of Thessaloniki (AUTH)
- Zalikas Liontas Techniki
- Municipal Enterprise of Water and Sewage of Chania
The project aims to develop a low-cost and large-scale pilot WSN for water management that will be able to augment the existing monitoring and management functionality of the Municipal Enterprise of Water and Sewage of Chania (DEYAX). Particular emphasis will be given on cognitive radio principles, not currently supported by commercial Zigbee-based WSNs and relevant standards. Such an approach is crucial for successful large-scale, city-wide deployment, given that the license-free Industrial Scientific Medical (ISM) frequency bands are usually crowded. The consortium will exploit its significant know-how on renewable energy sources, both solar and wind, in order to design autonomous micro-powering of the installed radio terminals and sensors. Furthermore, the project spearheads low-cost sensors appropriate for water level. It is remarked that existing level sensors are usually of high cost and imported. Moreover, the consortium will capitalize on its award-winning experience on in-network processing of acquired (sensed) data, including periodic or streamlined (aggregate) measurements. In-network processing offers intelligence in the system, while reducing the required communication bandwidth, since redundant information is not re-transmitted. Furthermore, the offered in-network intelligence will simplify the design of sensors, significantly reducing their cost, and will offer resistance to sensor outlier readings. DEYAX will offer the fertile experimentation ground, since a subset of their watering system, including storage/distribution tanks and pipes will be networked with the proposed system. Concrete quantification of the benefits will be performed in conjunction with other WSN-free parts of the watering infrastructure. It is remarked that DEYAX and members of the AquaNet consortium have already successfully collaborated in other applications.

For this project, GET developed application which offers access to project’s geospatial data. Moreover, the application which works as an application client for geospatial data services based on open standards. Basic features and functions are:
- Compatibility with global and widespread used geospatial information standards, like: WMS, WFS, WFS-T, WMTS, CSW
- Multiple different services integration on the same map
- View, download, search and analysis functions
- Metadata catalogues searching
Application development was based on GET SDI Portal.
