A large number of non-intrusive techniques can be used to identify buried archaeological deposits from the surface. These include:

• Resistance tests: based on the properties of materials to drive an electric charge, which can detect walls, ditches and wells, depending on the moisture content.
• Magnetometry testing: Based on the records of magnetic properties of soils and deposits. It can be used to identify buried archaeological remains.
• Geo-radar, which picks up the signal from underground deposits and can provide a bi-dimensional or tri-dimensional vision of the underground structures.

The most popular projects for these techniques are:

• Studies based on surveys of archaeological, ethnological and paleontological heritage.
• Geological heritage assessment.
• Archaeological park design, schools of thought for heritage evaluation.
• Excavation planning.
• Cemetery mapping.
• Cultural resources assessment.
• Grave and catacomb location.
