Abstract Hydrogeological data is
currently stored in national databases and available exclusively for a national user in a local language. Therefore the
data across the national borders forms separated, uncorrelated, not interoperable data sets. As the result much of the
hydrogeological spatial information is not involved in cross-border ground water management. At the same time geo
-data market research shows that the hydrogeological data is of great market demand, occupying the second
position in the rating list immediately after the data on rock composition (lithology).
The main objective of the new
EC co-funded project “Multilingual cross-border access to ground water databases” (eWater) is to increase the
cross-border availability, accessibility and re-usability of spatial data on quality, location and use of subsurface
waters. This is to be achieved via development of an Internet system that provides cross-border multi-lingual access
to ground water spatial data sets stored in the national databases of the participating countries. The system primarily
concern groundwater monitoring measurements, such as water level and chemical composition, as well as digital
hydrogeological maps (www.eWater.eu ).
The project lasts from September 2006 to August
2008. It involves twelve Geological Surveys and three commercial data service companies:
Geological Survey of the Netherlands(TNO)
2. Geological Survey of France (BRGM)
Geological Survey of Denmark and Greenland (GEUS)
4. Geological Institute of Hungary (MAFI)
5. Geofond – Czech Geological Survey
6. Geological Survey of Slovak Republic (GSSR)
Geological, Seismic and Soil Survey of Emilia-Romagna Region; the Emilia-Romagna Regional geological office
(SGSS ) is a part of the Italian Geological Survey.
8. Geological Survey of Austria (GBA)
Lithuanian Geological Survey (LGT)
10. Geological Survey of Slovenia (GeoZS)
11. The Geological
Survey of Spain (IGME)

the eWater system we analyzed organizational and institutional aspects of ground water data management at the
national levels that are considerably different in the participating countries. Then we collected the information
regarding availability and interoperability of hydrogeological maps. Further we analysed the existing technical
solutions (Best Practices) regarding description, collection, storing, retrieving, evaluating and distributing
hydrogeological data. Afterwards we identified the requirements for data delivery at EU and national users’ levels.
Based on the results of the research we developed eWater system prototype that would be converted to the
operational system by August 2008.
The distinguishable features of the eWater system are:
central web portal is designed as a focal point for publishing the hydrogeological data from participating EU
2. It provides common user interfaces into different national databases
different countries, having various database structures, it delivers common data sets in a unified XML format.
It offers on-fly-translation services for user interfaces and data itself
5. A special eWater-Mobile
module enables water specialists, operating in the field, to check recent groundwater measurement by means of a
mobile handheld computer (PDA in combination with GPS).
We would like to thank the
EC eContent Plus program for funding the eWater project. Also we acknowledge the support given by the
European geological surveys and institutes in sharing their knowledge and IT experience.
