Abstract

The article presents the results of the GPS and photographic surveys conducted on the archaeological site of Villa Magna (Anagni, Lazio). The archaeological complex, identified as the imperial residence of Antoninus Pius, occupies an area of about 22 hectares. Presently, the visible remains are divided into two principal nuclei: the northern one, near the church of S. Pietro, and the southern one, occupied by a farmhouse. The aim of the survey was the reconstruction of the morphology of the terrain in order to produce a Digital Terrain Model and to highlight the relationship between natural elements and ancient structures. In order to speed up the work, a new procedure was used. It consists of a Differential GPS used in a kinematic way by mounting the rover antenna on a jeep. In this article the experimental method’s advantages and the problems of acquisition are analysed. Moreover, low altitude photographs of the archaeological excavations were taken using an aerostatic balloon. The photographic system was anchored to the balloon with a radio-controlled device called Picavet. Georeferenced photos can be very useful not only for documenting but also for presenting and exploiting the site.
