  2. Lidar - Wikipedia

    en.wikipedia.org/wiki/Lidar

    Lidar (/ ˈlaɪdɑːr /, also LIDAR, LiDAR or LADAR, an acronym of "light detection and ranging" [ 1 ] or "laser imaging, detection, and ranging" [ 2 ]) is a method for determining ranges by targeting an object or a surface with a laser and measuring the time for the reflected light to return to the receiver.

  3. Lidar traffic enforcement - Wikipedia

    en.wikipedia.org/wiki/LIDAR_traffic_enforcement

    Lidar traffic enforcement. Lidar has a wide range of applications; one use is in traffic enforcement and in particular speed limit enforcement, has been gradually replacing radar since 2000. [1] Current devices are designed to automate the entire process of speed detection, vehicle identification, driver identification and evidentiary ...

  4. Radar detector - Wikipedia

    en.wikipedia.org/wiki/Radar_detector

    A radar detector is an electronic device used by motorists to detect if their speed is being monitored by police or law enforcement using a radar gun. Most radar detectors are used so the driver can reduce the car's speed before being ticketed for speeding. In general sense, only emitting technologies, like doppler RADAR, or LIDAR can be detected.

  5. Atmospheric lidar - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_lidar

    Atmospheric lidar. Atmospheric lidar is a class of instruments that uses laser light to study atmospheric properties from the ground up to the top of the atmosphere. Such instruments have been used to study, among other, atmospheric gases, aerosols, clouds, and temperature.

  6. Remote sensing in geology - Wikipedia

    en.wikipedia.org/wiki/Remote_sensing_in_geology

    Richat Structure by Shuttle Radar Topography Mission (SRTM). Instead of being a meteorite impact, the landform is more likely to be a collapsed dome fold structure.. Remote sensing is used in the geological sciences as a data acquisition method complementary to field observation, because it allows mapping of geological characteristics of regions without physical contact with the areas being ...

  7. LAS file format - Wikipedia

    en.wikipedia.org/wiki/LAS_file_format

    The LAS (LASer) format is a file format designed for the interchange and archiving of lidar point cloud data. It is an open, binary format specified by the American Society for Photogrammetry and Remote Sensing (ASPRS). The format is widely used [1] and regarded as an industry standard for lidar data. [2][3]

  8. Geological structure measurement by LiDAR - Wikipedia

    en.wikipedia.org/wiki/Geological_structure...

    LiDAR (Light Detection and Ranging) is a rapid surveying process that emits and receives laser pluses to acquire 3-D information. [3] By illuminating lights with different wavelengths to the object of interest, LiDAR can be used to create precise topographic maps, with applications in: geology, geomorphology, surveying and other applications. [3]

  9. Laser rangefinder - Wikipedia

    en.wikipedia.org/wiki/Laser_rangefinder

    A laser rangefinder, also known as a laser telemeter, is a rangefinder that uses a laser beam to determine the distance to an object. The most common form of laser rangefinder operates on the time of flight principle by sending a laser pulse in a narrow beam towards the object and measuring the time taken by the pulse to be reflected off the ...
