Abstract
The purpose of this paper is to present the state-of-art of groundwater geospatial information management, highlighting the relevant data model characteristics and technical implementation of the European Directive 2007/2/EC, also known as the INSPIRE Directive. The maturity of the groundwater geodata management systems is of crucial importance for any kind of activity, be it a research project or an operational service of monitoring, protection or exploitation activities. An ineffective and inadequate geodata management system can significantly increase costs or even overthrow the entire activity ([1-3]). Furthermore, following the technological advancement and the extended scientific and operational interdisciplinary connectivity at national and international scale, the interoperability characteristics are becoming increasingly important in the development of groundwater geospatial information management. From paper recordings to digital spreadsheets, from relational database to standardized data models, the manner in which the groundwater data was gathered, stored, processed and visualized has changed significantly over time. Aside from the clear technical progress, the design that captures the natural connections and dependencies between each groundwater feature and phenomena have also evolved. The second part of our paper address the variations that occurred when outlining the different groundwater geospatial information management models, differences that depict the complexity of hydrogeological data.
Highlights
The present paper proposes an analysis of the current forms of management and storage for geospatial information used in hydrogeology
The research has a main focus on investigating the relevant data model characteristics and technical implementation guidelines of the European Directive 2007/2/EC, the Hydrogeology Data Scheme - which together with the Geology Data Scheme and Geophysics Data Scheme form the Geology Theme
The direction of geodata management in geosciences is clearly steered towards using non-proprietary, modeling languages, compliant with international standards that would allow a seamless integration, usage and visualization of geodata
Summary
The present paper proposes an analysis of the current forms of management and storage for geospatial information used in hydrogeology. Standardization of a data model permits a common language between all parties involved, be they part of the academia, private or public sector. It allows interoperable sharing of data, be it among different entities, or different countries. In the current international context, when proper water resources management is crucial for a sustainable development, it is essential that the groundwater research community takes advantage of the significant progress that has been achieved in Computer Science. In the highly specialized scientific world of today, taking advantage of the developments in the different adjacent domains translates into highly effective results leading to progress and new research directions
