Satellite data and imagery indicate the large part of the landslide directly above the fjord waters began sliding on August 23, 2022. The slide is currently moving at a rate of 1.6–2.7 in (41–69 mm) each day. However, the volume of the landslide remains undetermined because the depth is uncertain.
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]
In 1986, the Jet Propulsion Laboratory requested and approved a quotation for the integration of a receiving ground station, the Alaska SAR Facility, at UAF. [12] The Alaska SAR Facility was marked at a ribbon-cutting ceremony on April 24, 1991. Later that year, the facility began down-linking European Remote Sensing Satellite-1 (ERS-1) data. [13]

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.
Geological structure measurement by LiDAR technology is a remote sensing method applied in structural geology. It enables monitoring and characterisation of rock bodies. [ 1 ] This method's typical use is to acquire high resolution structural and deformational data for identifying geological hazards risk, such as assessing rockfall risks or ...
Lidar (/ ˈ l aɪ d ɑːr /, also LIDAR, 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.
