Abstract

In the last ten years there have been several steps ahead towards the GIS 3D, in particular for the visualization of 3D objects within a GIS; few, instead, are the prototypes of GIS systems operating in 3D. The use of 3D Pdf is an intermediate solution that uses an open format such as .pdf and a series of free and open source software like Blender and PostgreSQL-PostGIS combined with programming languages such as Python and scripting languages such as Javascript. The aim of this paper is to describe a procedure for the interaction between a 3D model and a 2D geographic database. The opportunity to experiment with 3D Pdf was the subject of the Master thesis Tecnologie avanzate di rilevamento, rappresentazione e diagnostica per la conservazione e la fruizione dei beni culturali at the University of Palermo; a survey and a study of the Castle of Maredolce is described and the data that were employed to create a product for the public use of the Castle.
