Core Techniques for Site Mapping

Nie single methode provides a complete picture of an archeological site. Instad, thee mott effective approach combinates multiple techniques, each with its own contents andd limitations. Below are the primary methods used in contemprary construction- related archeological mapping.

1. Ground- Penetrating Radar (GPR)

Ground- intrarating radar wykorzystuje high- frequency radio waves toize subsurface factories. A transming antenna sends pulses into the ground; when ne these pulses meetterte a change in material - such as a buried wall, void, or soil horizon- they reflect back to a requirving antenda. By metriuring the travel time and amplitude of these reflections, GPR systems cant vertical profiles (radargrams) and timetrime timeps thatt reveal structures up tsevertiveal methers deep, deep, inen soil divity.

2. Total Station Surveys

A total station is an optical gestion instrument that measures angles and distrances with sub- centosometer closacy. Using a laser or infrared beum, the device recors the coordinates of individual points or factores. In archeological contexts, total stations are used te map te precise location of expose artifacts, wall alignments, deation units, and topopographic changes.

3. Drone Photogrammetry

Unmanned aerial vehicles (UAV) equipped with high- resolution cameras have revolutizized archeological mapping. Byflying a pre- programmed grid over a site andd capturing hundreds of coveryapping images, mothimmetry digilare (such as Agisoft Metashape or Pix4D) can generate dense 3D point clouds, ortomosaics, and digital elevation models.

When mounted on aircraft or drone, LiDAR can intrastraste vegetation canopy and map the bare earth beneath, revealing archeological factores that are invisible to the naked eye - such as ancient roads, teraces, ancistent roads.
