The project was aimed at the creation of software tools for managing instances of a multi - representation geodatabase, able to define multiple representations and topological constraints, in relation to modelled objects and structures according to the classification of IntesaGIS first and, later, the Italian national technical specifications of the November 10, Italian Ministerial Decree 2011.

Abstract

The project was aimed at the creation of software tools for managing instances of a multi - representation geodatabase, able to define multiple representations and topological constraints, in relation to modelled objects and structures according to the classification of IntesaGIS first and, later, the Italian national technical specifications of the November 10, Italian Ministerial Decree 2011. An original conceptual model was created, capable of expressing the different representations (scale, time) of the same geographic entities and relationships between them, directly into the geodatabase structure, by inserting an additional level of abstraction. In addition, various software tools were developed to create the database schema and its population using command line on Windows and Linux systems, as well as a graphical interface. The final goal is to be able to meet the needs of the production and use of geographical information with spatial and temporal components, with four dimensions: structure, space, time, and multiple representations. These dimensions are perpendicular to one another and enable individual operations to be performed independently of each other.
