Electronic Visualization of Underground Tourist Routes on the Example of the Route in Sandomierz

Summary/Abstract: For many years in Poland, anthropogenic objects constructed underground have been very popular with tourists. In the past they fulfilled various functions (historic mines, underground merchant warehouses, military objects, special objects, caverns and grottoes). Many of them were secured and rebuilt in such a way that a new form was created. They make interesting tourist offers and still more objects can be made available to tourists. An example of strongly modified underground anthropogenic objects of very complex geometry and extremely interesting architectural form is the Underground Tourist Route (Polish: Podziemna Trasa Turystyczna – PTT) in Sandomierz. Owing to much effort and financial means, in 1960s many interesting cellars and merchant warehouses were saved from destruction – and – with the application of mining techniques, they were joint into attractive spatial forms. So far, few publications give the full characteristic and parametric data of this object. Today’s possibilities of available measurement and information technologies allow comprehensive inventory of complicated engineering constructions, as well as the 3D visualization, regarding even tiniest elements of small architecture (doors, lattice, lamps, etc.). The article presents the results of the visualization and parameterization based on the data from integrated surveying (levelling, transects, total stations, laser scanning and other direct measurements).
