Resumen
The research expedition of the CNR-ITABC in the archaeological site of Umm Al-Rasas, near Madaba (Jordan) was partially supported by the Italian Foreign Ministry. It started in 2013 and was mainly focused on the 3D documentation of two Byzantine churches with magnificent floor mosaics, dedicated to Saint Stephen and Bishop Sergius respectively. To improve the analysis of the archaeological structures, different investigation techniques were used and reciprocally integrated, in an effort to create geometric models enabling the interpretation of data related to the masonry and floor mosaics, as well as to the documentation of the archaeological area. In order to facilitate handling and mobility, lightweight tools were chosen and Micro Photogrammetry and Close Range Photogrammetry methods were applied. A correct description of the floor warp was achieved thanks to laser scanner techniques and the resulting geometric data were integrated with the chromatic data coming from photogrammetry, obtaining a 3D restitution of the two adjacent structures and a metric and spatial analysis of their morphological features. New devices, specifically designed for the project, helped to solve some practical problems that the survey operations had to cope with during the fieldwork. This paper illustrates the results of the survey, which will be useful to develop restoration projects in order to make the whole archaeological site attractive to tourists.
