Terrestrial and Airborne LiDAR Digital Documentation of Petroglyphs in Three Regions of the National Park Service: Hawaii

Project Description:

Prehistoric Native American petroglyphs are one of the most unique and threatened archeological resources in the National Park Service (NPS). These endangered sites represent a significant addition to understanding prehistoric North American art, Native American belief systems, and cultural landscapes. Across the NPS system, petroglyphs range from those that are well-studied to those with little to no documentation. Conditions of petroglyphs range from near pristine to highly-eroded, and some are hard to discern and almost invisible to even the trained eye and seen only during certain lighting and weather conditions. Nearly all are at risk as they are being worn and abraded by anthropogenic impacts and natural effects of weathering, acid-rain, and waterborne sediment erosion. Others are also threatened by climate change, including inundation by rising sea level, impact from expanded fire areas, and surface erosional factors. This project work included the documentation of petroglyph resources across three NPS regions using advanced imaging, 3D laser scanning and spatial recordation techniques.
