The images are then taken and processed by an archaeologist who specializes in satellite remote sensing in order to find any subtle anomalies on the Earth's surface. ![]() The infrared light used by these satellites have longer wavelengths than that of visible light and are therefore capable of penetrating the Earth's surface. Satellite archaeology is an emerging field of archaeology that uses high resolution satellites with thermal and infrared capabilities to pinpoint potential sites of interest in the earth around a meter or so in depth. Although these are sometimes classed as remote sensing, they are usually considered a separate discipline (see Geophysical survey (archaeology)). Ground-based geophysical methods such as Ground Penetrating Radar and Magnetometry are also used for archaeological imaging.
