AbstractGeospatial technologies have proved their enormous value for different aspects of the archaeological work, being one of them their ability to allow the description and documentation of archaeological features at larger scales and with higher detall than ever before. In this paper we shall present an overview of the process of documentation and mapping of an area of ancient fields and irrigation channels around the prehispanic settlement site of Topaín, in the Andean periphery of Northern Chile. As opposed to the usual conditions for prospection in temperate regions, where the visibility of archaeological features is usually poor and confusing, here the extreme dryness of the landscape allowed an extraordinary condition and visibility of fields, channels and other constructions. The use of high resolution satellite images, combined with GPS, allowed us a fast and accurate mapping and documentation of more than 1000 individual features in less than two months of fieldwork. But besides mapping, this approach has provided with a better understanding of how all that system was built, evolved and changed in time, allowing the proposal of a sound hypothetical sequence of the use and transformation of this area before and after the inca period.
