Question restatement: Which of these is a remote sensing technique used in modern archaeology? (choose all that apply)

Option 1: Ground Penetrating Radar
- This is a geophysical remote sensing method that uses radar pulses to image the subsurface. It does not require digging to detect hidden features and is widely used in archaeology to locate walls, voids, and burials beneath the ground. Its remote sensing character comes from its ability to sense subsurface structures from the surface without intrusive excavation.

Option 2: Drawing maps
- While drawing maps is a cartographic activity important for documenting sites, it is not a remote sensing technique. Remote sensing involves collecting data about the Earth from a distance using sensors (satellites, aircraft, drones). Drawing maps itself does not involve remote sensing data collection.

Option 3: Excavation
- Excavation is a fundamental archaeological method but it is not remote sensing. It involves physically removing soil to uncover artifacts or features. It is an in-situ, hands-on investigative technique rather than remote sensing data collection.

Option 4: Carbon dating
- Carbon dating (radiocarbon dating) is a dating method for determining age, not a sensing technology. It requires physical samples and laboratory analysis, not sensing from a distance or from above. Therefore, it does not count as remote sensing.

Option 5: LIDAR
- Light Detection and Ranging (LIDAR) is a classic remote sensing technique that uses laser light to measure distances to the ground or objects. In archaeology, airborne or UAV-based LIDAR can reveal microtopography and hidden structures beneath vegetation, making it highly valuable for mapping sites remotely.

Summary: Among the options, Ground Penetrating Radar and LIDAR are remote sensing techniques used in modern archaeology. Drawing maps, Excavation, and Carbon dating are not remote sensing techniques.
