WebThe Earth is almost spherical, however there is a tiny bulge at the equator that makes it ~0.33% larger than at the poles. The ellipsoid is an approximation and does not fit the Earth perfectly. There are different ellipsoids in use, some are designed to fit the whole Earth (WGS84, GRS80) and some are designed to fit a local region (NAD27). WebThe ECEF coordinate system has the following parameters: The origin at the center of the chosen ellipsoid. In WGS 84, this is center of mass of the Earth. The Z axis is the line between the North and South Poles, with positive values increasing northward. easy bush tucker recipes

WebAn NOAA paper, Transformations Between NAD83 and WGS84, provides a clear, readable explanation. It recommends you use interactive "Horizontal Time-Dependent Position" software, HTDP, available on the NOAA Website at http://www.ngs.noaa.gov/TOOLS/Htdp/Htdp.shtml. As with any spatial reference system, ECEF consists of an abstract coordinate system (in this case, a conventional three-dimensional right-handed system), and a geodetic datum that binds the coordinate system to actual locations on the Earth. The ECEF that is used for the Global Positioning System (GPS) is the geocentric WGS 84, which currently includes its own ellipsoid definition. Othe…
