GIS-based hydrogeological databases and groundwater modelling

Microbiological and hydrogeological assessment of groundwater in southern Italy

This study represents the first investigation of microbiological groundwater pollution as a function of aquifer type and season for the Apulia region of southern Italy. Two hundred and seven wells were randomly selected from those monitored by the Regional Agency for Environmental Protection for emergency use. Both compulsory (Escherichia coli, Total Coliform, and Enterococci) and optional (Pse...

Rule-Based Modelling In GIS

Geographic Information Systems (GIS) provide functionality for visualising, managing and manipulating spatially referenced data. For straight forward spatial queries users perform these functions through a graphical user interface, for more advanced spatial models the user is often required to write a program as a formulation of the problem. The objective of this paper is to find out what type ...

Voronoi Region-Based Spatiotemporal GIS Databases

The use of Voronoi diagrams in GIS-oriented spatiotemporal databases is considered. The Voronoi algorithms generate appropriate meshes for data interpolation. We illustrate the data representation in this database generated from a point-based spatiotemporal relation in the National Agricultural Statistics Service (NASS) database.
