Which remote sensing technology uses laser pulses to create precise three-dimensional topographic maps?
Answer
LIDAR
LIDAR stands for Light Detection and Ranging. This specific remote sensing technology operates by emitting pulses of laser light towards a planetary surface. By measuring the time it takes for these light pulses to return to the instrument, scientists can calculate the precise distance to various points on the surface. This collected range data is then processed to generate highly accurate, detailed three-dimensional topographic maps of the planetary landscape, revealing elevation changes and surface structure.
