The topographic elevation of a summit measures the height of the summit above a geodetic sea level. [1] The first table below ranks the 13 major summits of Hawaiʻi by topographic elevation. The topographic prominence of a summit is a measure of how high the summit rises above its surroundings.
The DTED format for level 0, 1 and 2 is described in U.S. Military Specification Digital Terrain Elevation Data (DTED) MIL-PRF-89020B, and amongst other parameters describes the resolution for each level: Level 0 has a post spacing of approximately 900 meters. Level 1 has a post spacing of approximately 90 meters.
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 National Elevation Dataset (NED) consists of high precision topography or ground surface elevation data (digital elevation model) for the United States. It was maintained by the USGS and all the data is in the public domain. Since the 3D Elevation Program came online, the NED was subsumed [1] into The National Map as one of its layers of ...
Global hydrological data based on the SRTM elevation data. Includes river networks, watershed boundaries, drainage directions, and flow accumulations. USGS Land Cover Institute: Set of links from the USGS for numerous land cover datasets. Although primarily US data, further down the list there is data for other continents.
USGS (United States Geologic Survey) is developing a 3D Elevation Program (3DEP) to keep up with growing needs for high quality topographic data. 3DEP is a collection of enhanced elevation data in the form of high quality LiDAR data over the conterminous United States, Hawaii, and the U.S. territories.
Height fields (also known as "2 1/2 dimensional surfaces") model three-dimensional phenomena by a single functional surface, in which elevation is a function of two-dimensional location, allowing it to be represented using field techniques such as isolated points, contour lines, raster (the digital elevation model), and triangulated irregular ...
Hawaii Route 190 leads south from Waimea and provides a shorter inland route to Kailua-Kona of 39 miles (63 km). According to the United States Census Bureau , the Waimea CDP has a total area of 39.3 square miles (101.9 km 2 ), of which 39.3 square miles (101.8 km 2 ) are land and 0.04 square miles (0.1 km 2 ), or 0.10%, are water.
