The Metrological Research of Machu Picchu Settlement: Application of a Cosine Quantogram Method for 3D Laser Data

Abstract

The purpose of this research is to look for a basic unit or units of measure (quantum), the multiplication of which would help delineate the outline of Inca settlements such as Machu Picchu. By making use of the statistical method developed by D. G. Kendall, the cosine quantogram, and dealing with data acquired through 3D laser scanning, we can answer the question about Inca imperial measurement system. Based on length measurements from the construction level of niches, we can conclude that an imperial system of measure existed. Three basic units of design were used in different ranks and functions of the building, as follows: 0.20 m; 0.41 m; 0.54 m.
