The web based interface offers two different ways to explore integrated database contents.

Abstract

The application presented is part of the integrated research “New Technologies, Land and Environmental Information” that University IUAV of Venice is carrying out. It is a web-based application using DBMS and GIS technologies, developed with the aim of :1) storing, managing and exploring geo-data provided by public administrations and private companies; 2) testing several models of representing data availability compared with information needed for land planning and management. Probably the implementation of the European thesaurus GEMET is one the most interesting items of the study. GEMET has the important function of contents semantic classification system with which is possible to evaluate how geo-data available meets information needed; GEMET contains a group of keywords with internal hierarchies and classifications that makes possible semantic comparisons and put in evidence the gap between available data and needed information. All information collected within research activities are stored in three databases mutually connected by an integrated structure which is the main data provider for the web-gis application. The web based interface offers two different ways to explore integrated database contents. The first way allows user to select a specific activity in the field of land management, showing the list of the needed geo-information and geo-data availability; the second way directly gives the “view” of data available in a specific geographical area.
