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.
The HAWAII MR1 is a seafloor imaging system developed by the Hawaii Mapping Research Group (HMRG) in 1991. [1] HAWAII MR1 is short for HIGP (Hawaiʻi Institute of Geophysics and Planetology) Acoustic Wide Angle Imaging Instrument, Mapping Researcher 1. [2] This system is the first to use all-digital signal processing. [2]
This is a list of GIS data sources (including some geoportals) that provide information sets that can be used in geographic information systems (GIS) and spatial databases for purposes of geospatial analysis and cartographic mapping. This list categorizes the sources of interest.
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.
Mobile mapping is the process of collecting geospatial data from a mobile vehicle, [1] typically fitted with a range of GNSS, photographic, radar, laser, LiDAR or any number of remote sensing systems. Such systems are composed of an integrated array of time synchronised navigation sensors and imaging sensors mounted on a mobile platform. [2]
LiDAR provides the full-waveform system, it enables the laser pulse to penetrate through canopies and vegetations. [16] This system allows obtaining bare-ground geological data points. Webster et al. have discovered new craters in Northern Canada by harnessing LiDAR data and digital terrain models.
A doppler lidar system was used in the 2008 Summer Olympics to measure wind fields during the yacht competition. [121] Doppler lidar systems are also now beginning to be successfully applied in the renewable energy sector to acquire wind speed, turbulence, wind veer, and wind shear data. Both pulsed and continuous wave systems are being used.
Module:Location map/data/United States Hawaii (island) is a location map definition used to overlay markers and labels on an equirectangular projection map of Hawaii (island). The markers are placed by latitude and longitude coordinates on the default map or a similar map image.
