Sak Tz'i', a Classic Maya center:: A locational model based on GIS and epigraphy

The ancient Maya hieroglyphic inscriptions of the upper Usumacinta region record an intensive interaction that took place among its regional capitals. The precise geographic locations of some of these sites are presently unknown. Through the application of the Gravity Model within the framework of Geographic Information Systems (GIS), we present the probable locations and possible territorial extents of a few of these: Sak Tz'i', Hix-Witz, and the Knot-Site. On this occasion, however, we concentrate our discussion on the role that the kingdom of Sak Tz'i' played in the geopolitical scenario of the region. It is our belief that this case study constitutes a good example of how, through a conjunctive approach that integrates the archaeological with the epigraphic data, GIS can represent an excellent analytical tool to approach archaeological issues such as the political organization of the Maya Lowlands during the Late Classic period.
