Abstract
Recent geophysical survey at the early urban center of the Gallinazo Group in the Virú Valley highlights the potential for a multifaceted approach to remote sensing on the desert coast of South America and underscores the value of these well-established techniques for the rapid and detailed mapping of complex urban architecture. The Gallinazo Group (100 B.C.-A.D. 700) was an early city home to a population of between 10,000 and 14,400 people living in a network of agglutinated houses, plazas, public buildings, and alleyways. In 2008, detailed analysis of the site was undertaken, integrating traditional excavation techniques, soil coring, magnetometry, and ground-penetrating radar to gain a better understanding of the urban morphology of the site. The results of this fieldwork were extremely successful, with large areas of the urban layout being mapped in great detail. This article presents results from our survey, highlighting the potentials and limitations of each technique.
