Spectral mixture analysis was further used to assess the land cover fractional abundances surfacing the buried remains useful for determining whenever the optimal spectral ranges assessed by a Separability Index are connected to the land cover fractional abundances.2.?Study Area and Test Sites SelectionFive archaeological areas (Figure 1a) were chosen for this study, as they are characterized by not fully excavated subsurface remains, with a sharp geometry, not too deeply buried (i.e., 10�C20 cm to 1 m) and with a width and length greater than two MIVIS pixels (3 m/pixel).Figure 1.(a) Location of the five study areas over a regional map.

..The Arpi archaeological area covers an ancient city of Apulia located 8 km NE of the modern city of Foggia in the open countryside and it is considered the metropolis of the ancient Daunia (Figure 1b) [9,10], also known by its Greek place name, Argyripta. Its territory of about 1,000 ha extended to the sea, and Strabo says that from the extent of the city walls one could gather that it had once been one of the greatest cities of Italy. As a protection against the Samnites, Arpi became an ally of Rome (320 BC) and remained faithful until after the battle of Cannae. Arpi enjoyed an economic recovery after the fall of the Roman Empire, but was then destroyed by the Saracens in the eleventh century and, according to medieval sources, it was populace of Arpi who settled nearby Foggia.

Excavations begun in the 1940s unearthed the foundations of Hellenic-Roman buildings, some of them boasting lovely mosaic floors. A necropolis was also found, with many graves and small cave burials, with many examples of Apulian vases with their red figures and geometric decorations, dating from between the fourth and third century BC. However, the most important Carfilzomib remnants are the ancient city stone walls. For this area, a previous study performed by [9] had identified on MIVIS imagery (Figure 1b) the spectral anomalies relative to the following not yet excavated archaeological structures: an ensemble of features relative to the whole ancient city external perimeter wall (the ��aggere��, about 10 Km), two features relative to the defensive structures along the perimeter (i.e. stone walls) and 15 features relative to the main stone streets entering into the ancient metropolis.The Aquileia archaeological area includes one of the largest and wealthiest cities of the Early Roman Empire that was destroyed by Attila in the mid-5th century.
