Abstract. This work is part of an interdisciplinary project whose overall objective is to reconstruct the pre-Hispanic biocultural process and use of space in the South American Gran Chaco (UNLP-CONICET Project Dinámica Cultural Chaqueña en el Holoceno Tardío). This region appears as a vast plain characterized by its forests and wetlands, comprising an area of over one million km², and is located in the central-south portion of the continent. Specifically, the Argentine territory of the Gran Chaco stretches from the Pilcomayo River to about –30º latitude, including the provinces of Chaco, Formosa, Santiago del Estero, and partly Salta, Jujuy, Tucuman, La Rioja, Catamarca, San Juan, San Luis, Cordoba, Santa Fe, and Corrientes. The results of the latest archaeological research oriented to the location of prehistoric human settlement and its relationship with the landscape are presented. We proceeded to use Geographic Information Systems (GIS), digital image processing, and remote sensing for the systematization and creation of new information. As a result, an algorithm that integrates archaeological thematic maps and allows for differential potential areas for locating archaeological sites was obtained. This contribution results in an improvement in the regional archaeological research, creating heritage value and, in turn, optimizes the survey of archaeological sites.
