Through a Mirror, Darkly: Using Multi-Sensor Imaging Surveys as Basic Data for 3D Spatial Analysis of Cave and Open-Air Rock Art

Summary

This paper explores and compares how quantitative spatial analysis of cave and open-air rock art can be derived from high-resolution, multi-sensor 3D digital reconstructions. For this project, three different types of survey data were collected at four prehistoric cave and rock art sites within the southern Cumberland Plateau of eastern North America.

The project survey methods include close-range photogrammetry, high-density laser scanning, and near-infrared (NIR) multispectral imagery. The case studies are used to compare the overall efficiency of different survey methods for mapping rock art spatial organization and production techniques. For example, while high-density laser scanning allows for rapid collection of data over large areas, high-resolution photogrammetry allows for greater precision in detecting and enhancing engraved or incised petroglyphs and mud glyphs. When possible, multiple data sets are fused to produce multi-sensor 3D objects that can be investigated using a variety of GIS, 3D, and computer-aided drafting (CAD) software tools.

Spatial patterns in the distribution and form of rock art glyphs and panels can reveal culturally linked concepts within a traditional knowledge system. Project results are interpreted based on relationships between spatial patterns, traditional knowledge, ethnohistory, and structural attributes.
