Question

DQ 5.2 Do you know which type of detection system might allow you to observe such a two-dimensional spectral ‘map'?​

Answer 1

Answer:

Lidar — Light Detection and Ranging — is a remote sensing method used to examine the surface of the Earth. ... These light pulses—combined with other data recorded by the airborne system — generate precise, three-dimensional information about the shape of the Earth and its surface characteristics.LiDAR can detect micro-topography that is hidden by vegetation which helps archeologist to understand the surface. Ground-based LiDAR technology can be used to capture the structure of the building. This digital information can be used for 3D mapping on the ground which can be used to create models of the structure.
