The Chacas Valley Project (Dep. of Ancash, Peru), coordinated by Prof. Laurencich Minelli of University of Bologna, is a partnership between the Ministry of Foreign Affairs, the over mentioned University and the Municipality of Chacas. The aim of such project is to carry out an archaeological and anthropological survey on pre-Columbian cultures of the valley. The collected data will be the base for planning some trekking route between the archaeological sites. In lack of sufficiently detailed maps, it has been necessary to define a cartographic reference system to cover all the investigated area. The knowledge of a detailed topographical surface is also crucial to build up an architectural model of the pre-Columbian urbanized areas. Consequently, the definition of this surface is necessary to locate the architectonic structures and to define their destination of use, and also to investigate the relationship between the architecture and the morphology of the landscape, a very important element in the urbanization system of pre-Columbian civilizations. Such information will be obviously of primary importance in order to define some tourist trekking paths between the archaeological zones. This paper introduce the topographic survey carried out in two archaeological expeditions (1998 and 2000) on the fortified Recuay citadels (II-VI sec. a.d.) Huacramarca and Riway. During the first expedition a traditional methodology has been applied while in the second one a relative kinematic satellite GPS (Global Positioning System) methodology was employed. The high productivity of the gps methodology allows to acquire many information in short time, also working in difficult situations (the over mentioned citadels are located at 4000 mt above m.s.l. In a very distant position from the nearest villages). Through gps survey was possible to perform at the same time a survey to define the position of archaeological structures and the morphology of the landscape. This methodology, which allows the space referencing of all the objects and the integrated analysis of the information, is a very powerful tool for the interpretation of the sites. The recollected data could constitute the first step towards the realization of a gis for the cultural heritage valorization of this area, and offer a research opportunity for archaeologist to gather geo-morphological information together with all the other data available from different source of observation.
