Precision GPS Surveying at Medieval Cottam,East Yorkshire,England

Abstract

To help promote the use of centimeter and sub-centimeter level GPS for surveying archaeological Sites, a series of tests was conducted at the deserted medieval village of Cottam in East Yorkshire,England. In order to understand the capabilities of the technology, the GPS system was tested for speed, accuracy, and reliability and the results were compared with those from a conventional total station. Using the capabilities of the total station as a benchmark, the GPS system's accuracy and reliability were found to be acceptable. The test system, however, was found to be considerably slower than the total station and much more difficult to use with equivalent levels of accuracy     

DEFINITION OF THE BOUNDARY OF MOSCOW'S ACTIVE ZONE OF INFLUENCE

The present boundaries of Moscow's suburban zone are tested by delineating a so-called zone of active influence of Moscow city based on demographic structure and the significance of commuting to work in the city. The most favorable age-sex structure, with a high percentage of population in the working age groups and a relatively high percentage of children, is found in a zone within 50 to 60 kilometers from the city limits. This zone generates a daily flow of more than 500,000 commuters to places of employment in Moscow, 90 percent of whom spend less than 110 to 120 minutes traveling each way. These commuters represent about 2 percent of the total working-age population in the suburban zone. On the basis of the demographic structure and commuting linkages, Moscow's zone of active influence is therefore defined as the zone within which 90 percent of the commuters reside, or within 52 kilometers of the city limits. This conforms roughly to the present definition of the suburban zone.     

A LYONS BRANCH OF THE POTTERY-MAKING FIRM OF ATEIUS OF AREZZO

Fifty-one waster sherds of Terra Sigillata (～20-0 b.c. ) from Arezzo, Italy and Lyons, France have been chemically analysed for twenty-eight elements by neutron activation and seven by X-ray fluorescence. Most of the elemental abundances were measured with high precision and cross-comparisons of the two techniques of measurement (and sample preparation) give added insight as to their relative precision, the calibration differences and the extent to which volatile materials such as carbonate or water influence the results. The sherds from Arezzo formed a homogeneous and distinctive chemical group while all but two of those from Lyons were classified into three such groups. Two of the Lyons groups (MML A and MML B) were from Montée de La Muette and one was from Loyasse. Four additional sherds from houses excavated in Strasbourg and one from Lyons, all of which bore the signature of the famous Anetine pottery-making firm of Ateius, were also analyzed by the same techniques. These signed sherds all had the same composition pattern and it closely matched one of those from Montée de La Muette (MML A) in Lyons. It is therefore suggested that these five sherds bearing the Ateius signature were made in the general vicinity of Lyons and were part of the output of an as yet unknown Gallic branch of the firm of Ateius.
