Remote sensing is a great support for research, providing data in different areas such as archaeological, geological, urban and environmental. A great variety of techniques of remote sensing is dominated, among them we emphasize: LAND SURVEY EQUIPMENT Currently for the area of archeology is used the method of Ground Penetrating Radar (GPR) or Georadar, with antennas of different frequencies. Non-destructive survey technique that allows the archaeologist to obtain a priori a precise map or estimate of the area to be excavated. Special software for three-dimensional simulation is used. IMAGES OF AIRBORNE AND SATELLITE SENSORS The airborne sensors, given their suitability in terms of resolution and application diversity, are used in projects of great technological complexity. Gravimetry and magnetometry techniques, thermal infrared imaging and multispectral sensors are used for the archeology and environment areas. We work with satellite imagery in studies that cover large areas or do not require high spatial resolution (scales less than 1: 10,000 for panchromatic, 1: 50,000 for multispectral, 1: 200,000 for other portions of the electromagnetic spectrum such as microwaves or for hyperspectral studies). AERIAL PHOTOGRAPHY It is used to obtain orthophotographies, topographical cartography and digital terrain models using the photogrammetric restitution method.
