This article outlines the basic difficulties for the modelling of a historical GIS data infrastructure on Bourbon Spanish America which aims at providing reconstructions of a dozen territorial "levels" and settlements across the double continent, from California and Louisiana to Patagonia, for a period of 108 years (1701-1808). Due to the manifold sources of uncertainty at many levels it is particularly demanding to successfully model the spatial embodiment of territorial entities and their change over time. In this text, we explain how we isolate different types of uncertainty and create different chronologies across the database. In more detail, we will show how we reassemble the different parts and integrate them into a geodatabase with a single chronology based on queries on the different partial chronologies. Also, we show how this workflow has been implemented to allow automatic creation of shapefiles from simple tables through the interface of our homepage. Instead of a narrative conclusion, we present a synoptic graphic visualizing how the different parts and processes provide a stable framework for a GIS data infrastructure covering a complete period of time --a framework that can be easily be re-implemented for different fields, regions, and periods.

This paper's objective is to elucidate the ways of space occupation in the Puna of Salta, from a regional perspective spanning various historical processes and discovering the associative principles of material evidence with the environment. We apply spatial analysis methods and techniques from the perspective of historical GIS, with the aim of contextualizing sites within a general explanatory framework for the analytical insertion of the domain of high altitude archaeology (archaeology of summits and tombs) in the regional history, which appears as discursive and methodological decoupled.
