What is UTM and WGS?
UTM and WGS both are examples of coordinate systems. The difference is that WGS is a Geographic coordinate system and UTM is a projected coordinate system. Geographic coordinate systems are based on a spheroid and utilise angular units(i.e. degree)
What is the datum for UTM?
Universal Transverse Mercator System Projection The origin of each zone is the equator and its central meridian. The value given to the central meridian is a false easting of 500,000. In the continental United States, the North American Datum of 1927 (NAD27) and the Clarke spheroid are most commonly used.
Is WGS 84 a datum?
WGS84 is defined and maintained by the United States National Geospatial-Intelligence Agency (NGA). It is consistent, to about 1cm, with the International Terrestrial Reference Frame (ITRF). It is a global datum, which means that coordinates change over time for objects which are fixed in the ground.
Is WGS 1984 a coordinate system?
The World Geodetic System (WGS) is a standard for use in cartography, geodesy, and satellite navigation including GPS. WGS 84 is the reference coordinate system used by the Global Positioning System.
Is WGS the same as UTM?
The difference is that WGS 84 is a geographic coordinate system, and UTM is a projected coordinate system. Geographic coordinate systems are based on a spheroid and utilize angular units (degrees).
Who uses UTM?
UTM is currently used by the United States and NATO armed forces. With the advent of inexpensive GPS receivers, many other map users are adopting the UTM grid system for coordinates that are simpler to use than latitude and longitude. The UTM system divides the earth into 60 zones each 6 degrees of longitude wide.
Is UTM an ellipsoid?
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 as a perfect ellipsoid.
Is WGS 1984 projected or geographic?
For example, the “WGS84 projection” is a geographic one. A UTM projection is a projected one. Either of these will use only one datum. However, the data on the map could have come from multiple sources, all with unique projections and therefore datums.
