Objectives

Methodologies for the acquisition and transformation of input data: Input data can come from a variety of sources: 2D data from CAD tools, paper drawings, geo-radar data, etc. This information should be transformed into 3D models.

Hybrid models: Define models of integration of volumetric and vector data. To study formal models, data structures and operations on such models. Use standard libraries as well as standard OGC specifications.

Definition of a spatial database: Define the elements corresponding to the underground infrastructures with vector characteristics (pipes, ducts, collectors, stopcocks, etc.) and raster (type of terrain, cavities, deserts, etc.) and define the Topological relationships between them. Define also the entities on the surface.

Visualization of 3D models: Study of efficient visualization methods considering the sections on the ground, the spatial arrangement, and the interactions between the diverse elements existing in the terrain.

Web-3D: Make all this possible also for ubiquitous devices. To do this, study possible visualization tools to be able to handle the application on mobile devices at street level.
