Survey and Recording

Archaeologists at Portus use a wide range of methods to explore the archaeology laying above, and below, the ground.

Processes such as photogrammetry, laser scanning and reflectance transformation imaging (RTI) allow researchers to examine, record and present the surface layers of the site and its artefacts in extraordinary detail.

Other technologies, such as ground-penetrating radar, sidescan sonar, and magnetometry give archaeologists the capacity to see into the earth and chart future excavations.
