The article tells of the use of GIS for identifying the boundaries of the Mayan state of Pa’Chan, centered around the city of Yaxchilán on the Usumacinta. The database created for the purpose of the present study has used the large corpus of written sources, the archaeological data and the specific features of the local landscape. Spatial GIS analysis of the region allowed identifying the hypothetical borders of the state, which had an area of about 1500 sq. km.
