3D in the Toolbox: An Operational Comparison of Acoustic, Photogrammetric, and Laser Scanning Methodologies Tested at Thunder Bay National Marine Sanctuary in 2016. (2017)
DOCUMENT Citation Only John C. Bright.

The clear, fresh waters of Thunder Bay National Marine Sanctuary offer an ideal testing ground for acoustic and light-based imaging systems. During the 2016 field season, Thunder Bay researchers conducted several field operations to acquire, process, and compare side scan sonar, multibeam sonar, laser-scanner, and photogrammetric data at numerous archaeological shipwreck sites. The resulting analysis provided valuable insights into this array of remote sensing systems in terms of their ability...

Accuracy and Precision of 3D Modeling in Lithic Analysis (2015)
DOCUMENT Citation Only Rebecca Biermann. Alison S. Brooks. David R. Braun.

Studies of stone artifacts increasingly rely upon measurements of 3D models, due to the ability to capture a larger range of volumentric and angular attributes on these models. Despite the enthusiasm for these new techniques, little research has been conducted on the efficacy of digital reconstructions for quantitative lithic analysis. The objective of this project is to quantify the advantages and disadvantages of two methods of 3D data capture (e.g. photogrammetry and laser scanning). We...

Adding Lasers to the Archaeological Toolkit: The Costs and Benefits of Terrestrial LiDAR in Digital Archaeology (2015)
DOCUMENT Citation Only Patricia G Markert. Benjamin Skolnik. Stefan F. Woehlke.

In recent years, companies such as FARO and CyArk have begun incorporating 3D laser scanners into field-ready packages.  Archaeologists have successfully employed these new 3D laser-scanning techniques to record sites such as Mount Rushmore and Merv in modern-day Turkmenistan.  Despite the potential benefits of using this technology, which produces quickly scanned, high-resolution images of topography and features, several limitations have slowed it from entering the archaeologist’s standard...

Applications of Cultural Heritage and Digital Preservation in Science, Technology, Engineering, and Mathematics (STEM) Education (2015)
DOCUMENT Citation Only Katia Chaterji. Alexander Reinhold.

This paper discusses the application of innovative 3D heritage documentation methods to augment science, technology, engineering, and mathematics (STEM) education. A California-based nonprofit dedicated to the digital documentation and preservation of cultural heritage sites worldwide, CyArk is a leader in digital heritage preservation, archival, and technological advancement. CyArk practices a range of techniques, including 3D laser scanning, high definition photography, and photogrammetry,...

Recording Historic Shipwrecks at the Speed of Light: An Archaeological Analysis of the ULS-200 Underwater Laser Scanner to Sonar, Video, and Photographic Recording Methodologies (2015)
DOCUMENT Citation Only Michael C. Murray.

Since the beginning of underwater archaeology, the effective recording of sites has always been a challenge. This study will compare the ULS-200 underwater laser scanning device to other traditional archaeological recording methods, seek to quantify the average amount of time it takes to conduct a scan underwater and evaluate its accuracy in resolving an image at different turbidities and ranges. Within its ideal range, the expected outcome is that while it will take an equal or longer amount of...

Terrestrial Laser Scanning: a methodology for documenting existing and extrapolating past setting on archaeological sites (2016)
DOCUMENT Citation Only Sudhagar Nagarajan. Christian Davenport.

The Jupiter Inlet I (8PB34) site is one of the most investigated prehistoric sites in Palm Beach County, Florida. Like many of the ancient shell works sites across the state it was partially destroyed for road fill during the first half of the 20th century. Only a sketch map of the site from 1883 depicts what the site looked like prior to destruction. Since then there have been attempts to reconstruct the mound form but these relied on verbal accounts and limited stick and scope survey...
