The Earth-centered, Earth-fixed coordinate system (acronym ECEF), also known as the geocentric coordinate system, is a cartesian spatial reference system that represents locations in the vicinity of the Earth (including its surface, interior, atmosphere, and surrounding outer space) as X, Y, and Z measurements from its center of mass.
Center the screen on your location by double-clicking on it, then use the View in Google Maps button at the top (Google Earth 4.1 and newer). This will open Google Maps within Google Earth. You can see the center coordinates in decimal format in the address bar, but unfortunately you cannot copy them directly.
The Universal Transverse Mercator (UTM) is a map projection system for assigning coordinates to locations on the surface of the Earth. Like the traditional method of latitude and longitude, it is a horizontal position representation, which means it ignores altitude and treats the earth surface as a perfect ellipsoid. However, it differs from ...
A geographic coordinate system (GCS) is a spherical or geodetic coordinate system for measuring and communicating positions directly on Earth as latitude and longitude. [1] It is the simplest, oldest and most widely used type of the various spatial reference systems that are in use, and forms the basis for most others.
Geodetic latitude and geocentric latitude have different definitions. Geodetic latitude is defined as the angle between the equatorial plane and the surface normal at a point on the ellipsoid, whereas geocentric latitude is defined as the angle between the equatorial plane and a radial line connecting the centre of the ellipsoid to a point on the surface (see figure).
Geocentric coordinate system (or Earth-centered Earth-fixed) A three-dimensional cartesian coordinate system that models the Earth as a three-dimensional object, measuring locations from a center point, usually the center of mass of the Earth, along x, y, and z axes aligned with the equator and the prime meridian.
The Open Location Code (OLC) is a geocode based on a system of regular grids for identifying an area anywhere on the Earth. [1] It was developed at Google's Zürich engineering office, [2] and released late October 2014. [3] Location codes created by the OLC system are referred to as "plus codes".
Google Earth is a free program for Linux Macintosh or Windows which displays satellite photos, road maps, and other forms of geospatial information. If you can find a location, landmark, landform, stationary object, etc., on a satellite photo or road map, you can easily get its coordinates from Google Earth.
