Abstract
The use of remote-sensing (RS) data, from imaging to scanning, has now become an integral and routine part of geoarchaeological studies. Even in the early days of aerial photographic imagery, it was realized that this technology could, under different light and ground conditions, reveal significant subsurface information, particularly in arable lands through so-called “crop marks” (Barber, 2011). In addition, site recording (or planning) was routinely augmented by high-resolution, oblique photography from extendable poles, or photographic towers (Fussell, 1982). This offered some three-dimensional (3D) capability from stereo pairs, but this was limited and digital photogrammetry has only really advanced with the advent of digital single-lens reflex (DSLR) cameras and sufficient computing power (Doyon et al., 2019)
