A national lidar dataset refers to a high-resolution lidar dataset comprising most—and ideally all—of a nation's terrain. Datasets of this type typically meet specified quality standards and are publicly available for free (or at nominal cost) in one or more uniform formats from government or academic sources.
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.
A common basemap, including current color leaf-off aerial photography and elevation data (LiDAR), reduces the cost of developing GIS applications, promotes data sharing, and add efficiencies to many state agency business processes. All basemap data acquired through this effort is being made available in the public domain. [14]
At the beginning of the self-driving car program, they used a $75,000 lidar system from Velodyne. [59] In 2017, the cost decreased approximately 90 percent, as Waymo converted to in-house built lidar. [60] Waymo has applied its technology to various cars including the Prius, Audi TT, Fiat Chrysler Pacifica, and Lexus RX450h.
Although LiDAR has been an effective data acquisition method on a rock slope, its high cost caused the technique to be not practical. [47] When the area of interest is of a very small scale, it limits the usability of TLS & ALS, given carrying out an ALS survey requires aircraft, an experienced pilot, a designed flying path and height that got ...
