Excavation is not a site survey method. It is a process of digging up and examining archaeological remains at a site.

The primary purpose of a site survey is to identify and record the location and characteristics of archaeological sites.

Pedestrian survey involves walking over a designated area and visually inspecting the ground for artifacts and features.

Ground-penetrating radar uses electromagnetic radiation to create images of the subsurface.

Geophysical survey involves using various techniques to measure the physical properties of the soil, such as its magnetic properties, to detect buried features.

Aerial survey provides a comprehensive view of a large area, allowing archaeologists to identify potential sites and features that may not be visible from the ground.

Grid survey involves dividing an area into grids and systematically searching each grid for artifacts and features.

Site mapping is the process of creating a map of an archaeological site.

Metal detector survey involves using a metal detector to locate buried metal objects.

The primary purpose of conducting a site survey prior to excavation is to identify and record archaeological sites.

Drone survey involves using a drone equipped with a camera to capture aerial images of an area.

Site analysis is the process of collecting and analyzing data from a site survey.

Magnetometer survey involves using a magnetometer to measure variations in the Earth's magnetic field.

Test excavation is the process of excavating a small portion of a site to gain information about its stratigraphy and features.

Resistivity survey involves using a resistivity meter to measure variations in the electrical resistance of the soil.
