“This research uses Geographical Information Science methods to establish spatial information pertaining to archaeological sites within the middle Malpaso Valley, Zacatecas, Mexico. Analysis of residual and Root Mean Square Error of geo-rectification produces both localized and overall geodetic accuracy assessments of a historic 1974 survey map. Ground control points acquired using Global Positioning System provide a basis for establishing confidence in the geo-rectified map. This research is a technological continuation of previous work in the Malpaso Valley, and aims to produce a useful map for spatial analysis and data management in future research.”
