  2. Moment distance index - Wikipedia

    en.wikipedia.org/wiki/Moment_distance_index

    A full-waveform Light Detection And Ranging (LiDAR) system has the ability to record many returns per emitted pulse, as a function of time, to reveal the vertical structure of the illuminated object, showing position of the individual targets, and finer details of the signature of intercepted surfaces or the proportion of the canopy complexity ...

  3. Lidar - Wikipedia

    en.wikipedia.org/wiki/Lidar

    Lidar (/ ˈ l aɪ d ɑːr /, 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.

    en.wikipedia.org/wiki/File:Flying_Through_LIDAR...

    However, lidar data does not specifically show individual leaves, but simply point heights reflected by the leaf canopy. However, the resolution of the lidar data is so good that it potentially can pick up leaves and other structures such as tree branches, and sometimes even flying birds, but has no easy way to differentiate between them.

  5. National Lidar Dataset (United States) - Wikipedia

    en.wikipedia.org/wiki/National_Lidar_Dataset...

    Currently, the best source for nationwide LiDAR availability from public sources is the United States Interagency Elevation Inventory (USIEI). [1] The USIEI is a collaborative effort of NOAA and the U.S. Geological Survey, with contributions from the Federal Emergency Management Agency, the Natural Resources Conservation Service, the US Army Corps of Engineers, and the National Park Service.

  6. 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]

    English: This visualization shows an airplane collecting a 50 kilometer swath of lidar data over the Brazilian rainforest. For ground level features, colors range from deep brown to tan. For ground level features, colors range from deep brown to tan.

    Use of NASA logos, insignia and emblems is restricted per U.S. law 14 CFR 1221.; The NASA website hosts a large number of images from the Soviet/Russian space agency, and other non-American space agencies.

  9. Remote Sensing Center - Wikipedia

    en.wikipedia.org/wiki/Remote_Sensing_Center

    Lidar ranges in wavelength from ultra-violet (0.3-0.45 μm) to visible (0.45-0.70 μm) to the infrared (1-15 μm). Lidar can detect much smaller particles than radar in the atmosphere (which cannot detect things smaller than cloud particles), and thus can be used for aerosol detection. The raw form of data is a set of x,y,z coordinate points.
