Overview

The regional significance of Quispisisa obsidian is evident from consumption patterns; it was transported to sites over 100 km from the source in the Early Holocene and by 500 BCE it was reaching sites nearly 1000 km distant from the source.  Research into the procurement of Quispisisa obsidian at its source promises to shed light on the timing, scale, and organization of the mining of this important material, while the settlement system and anthropogenic landscape of the surrounding

Finding the right transformation when re-projecting data in ArcGIS 9.2

So you're using the Project Tool to re-projecting a map into a new projection.

Before you can start the process, you have to choose from the many transformations. The attached file (World Projections.xls) lists where in the world each projection transformation should be used.

For example, if your map is in PSAD56, and you want to project it to WGS84, the Project Tool will ask you which transformation you want. Checking the lists for Bolivia, I find: PSAD_1956_To_WGS_1984_2
