Photogrammetry

Definition

Photogrammetry is the technique of obtaining reliable measurements and detailed information about physical objects and the environment through the process of recording, measuring, and interpreting photographic images. This method connects to recording archaeological data by allowing researchers to create accurate 3D models of sites and artifacts, which enhances documentation and analysis. Additionally, photogrammetry has evolved over time, influencing the study of archaeology from its early applications in mapping to its modern integration with digital technologies.
