3D MODELLING OF HISTORIC URBAN CENTRES AND ITS APPLICABILITY TO THE FIELDS OF SECURITY AND DEFENCE

Abstract

Historical cities (or centers) show a value which goes beyond the
properly historical or cultural, being considered as milestones for the
own collective memory of its inhabitants. Because their strategic value,
it is of paramount importance to develop research lines for increasing
our knowledge about them.
In this article, we propose a proper methodology for the generation
of three-dimensional digital models considering the characteristics of
historical urban centers. This methodology is based on the combined and
complementary use of photogrammetry and laser scanner. The models
finally obtained for each building are geometrically precise and visually
aesthetic. These models can be integrated into virtual environments,
and used for safety of historical cities, which are especially vulnerable
against war or terrorist actions.
