Métodos topocartográficos para la documentación de mosaicos in situ. Aplicaciones en la villa tardorromana

Abstract

The Roman villa of Torrexón de Veranes can be found in the council of Gijón, very close to the ancient crossroads which connected the Roman city of Gijón and the central Asturian area with the Asturica Augusta, a road identified as the transmountain branch of the Ruta de la Plata, or Silver Road. The results obtained in the systematic excavations begun in 1997 allow us to identify two well-defined moments of occupation: a high imperial establishment from which very little architectonic evidence has been preserved, and the construction of a large, late Roman farming and fishing complex in which four rooms paved with mosaics have been documented. This documentation has been carried out using a topo-cartographical work methodology for collecting data. This registry method allows us to obtain a graphic representation and the metric description of the original state of the mosaic through the use of combined photographic techniques, proving it as a faster and more accurate method than the traditional system of 1:1 scale copies as an alternative to traditional photogrammetry.
