Archaeology is most often thought of as the act of excavating. While excavation is the primary form of collecting data, it is also destructive as well as expensive, creating a need for other ways of retrieving data, which both complement the excavation data, as well as assist in planning an excavation. This is usually referred to as archaeology survey, which includes various methods of non-intrusive data collection, in order to learn about a site or region.
