A team of researchers led by archaeologists from the University of Arizona has used a laser mapping system from the air to uncover the buried ruins of an ancient Mayan site. After determining that an area in Tabasco in the southeast part of Mexico was worthy of further study, the researchers zeroed in on a particular location with lidar. Lidar stands for light detection and ranging, a remote sensing method that uses light from a pulsed laser to measure varying distances to the ground.

    lidar
    Lidar, short for light detection and ranging, is a remote sensing technology that uses laser light to measure distances and generate precise, three-dimensional information about the shape and characteristics of objects and surfaces. Lidar systems typically consist of a laser scanner, a GPS receiver, and an inertial measurement unit (IMU), all integrated into a single system. Here is how lidar works: Laser emission: A laser emits laser pulses, often in the form of rapid and repetitive laser...
    remote sensing
    Remote sensing is a method of data collection and observation where information about objects, areas, or phenomena on Earth's surface is gathered from a distance, typically using sensors onboard satellites, aircraft, drones, or other platforms. This technique enables the monitoring and analysis of Earth's surface and atmosphere without direct physical contact. Remote sensing systems capture electromagnetic radiation (such as visible light, infrared, microwave, or radio waves) reflected or...
