Geomatics in hydrogeology

Michalak J.

Geological Quarterly

Vol. 47, No 1

69-76

Design and construction of hydrogeological information systems is now a necessity. For proper functionality of these systems, it is necessary to create them in accordance with widely accepted international standards regarding geospatial information. Geomatics research tools allow for creation of basic models of hydrogeological data, consistent with these standards. The models can be based upon classification of types and subtypes of hydrogeological features, as well as upon basic and derived classes of hydrogeological objects. The basis for this classification can be differentiation between features and objects, as well as between fuzzy features (objects) and fiat features (objects), or the analysis of their spatial dimensionality.

Features and coverages in hydrogeological information

247-255

In recording hydrogeological information in computer system (databases GIS), it became necessary to manipulate them in a consistent and efficient way. The correct functioning of these systems depends principally on the applied data models, which should be based on commonly accepted international standards of geospatial information. This is particularly important in the case of interoperability of different systems, for example a system simulating hydrogeological processes and the hydrogeological geospatial database system. The research tools of geomatics allow the construction of data models of such systems conformable to these standards. However, in the definition of such a model several ontological and semantic inconsistencies arise. Two examples are taken for consideration: hydrogeological feature and coverage. These terms are frequently applied improperly to cases of geospatial information. Definition of these terms in a hydrogeological context will prevent ambiguities in formulating models of hydrogeological data.
