The Recording and Preservation of Features
that cannot be excavated
Often, written and oral sources reveal the existence of archaeological remains in the subsoil of areas than cannot be excavated or where excavating is not convenient (busy streets, churches, etc.).
Surveying the area by means of different geophysical sensors facilitates the acquisition of information about the site from the surface with no need for excavation, that can be used as an alternative source of information. Therefore, geophysical survey is in these cases an alternative way of recording heritage.
In England, the English Heritage already uses this prospection technique as a tool for documenting archaeological sites and entering them into the country’s archaeological records.
