ADVANCES IN PHOTOGRAMMETRYWithin the past few years, photogrammetric technology has become an emerging tool for archeologists to map and document features or entire shipwreck sites underwater. Photogrammetry uses two-dimensional image sequences from multiple perspectives to create a three-dimensional visualization of an object. The SRC is testing this technology against known mapped shipwrecks to determine accuracy and feasibility as well as adapting new photogrammetric mapping project to document underwater sites across the National Park system.
