Universal Transverse Mercator
Universal Transverse Mercator, UTM
A map projection and plane coordinate system based on sixty north-south trending zones, each 16 degrees of longitude wide, that circle the globe. The UTM grid is used commonly in GIS technology in the United States.
UTM - Universal Transverse Mercator Geographic Coordinate System
The idea of the transverse mercator projection has its roots in the 18th century, but it did not come into common usage until after World War II.
Universal Transverse Mercator (UTM)
The Universal Transverse Mercator is an international plane (rectangular) coordinate system developed by the U.S. Army. The UTM divides the world into 60 zones of 6 degrees longitude.
Universal Transverse Mercator (UTM)
The UTM system was an attempt to set up a universal world wide system for mapping. The Transverse Mercator projection is used, with the cylinder in 60 positions. This creates 60 zones around the world.
Universal Transverse Mercator Grid System (UTM)
This system is a specialized application of the transverse Mercator projection which is both cylindrical and conformal. It divides the world into 60 numbered zones, both north and south, separated by the equator.
The UTM coordinate system is commonly used in GIS for larger scale areas within a certain UTM zone. The UTM projection is formed by using a transverse cylindrical projection, i.e., the standard line runs along a meridian of longitude.
~ (UTM) The UTM projection is a projection accepted worldwide-accepted for topographic mapping purposes. It is a version of the Transverse Mercator projection, but one with a transverse secant cylinder.
A mathematical transformation of he earth's surface to create a flat map sheet. The UTM projection is well suited for small areas.
A nearly worldwide coordinate projection system using north and east distance measurements from reference point(s). UTM is the primary coordinate system used on U.S. Geological Survey topographic maps.
~ (UTM) grid Military grid system based on the transverse Mercator projection, applied to maps of the Earth's surface extending from the Equator to 84 Degrees north and 80 degrees south latitudes upland Highland; ...
a series of 120 coordinate systems that are based on the transverse Mercator projection that was originally developed by the US Army for a worldwide mapping project.
~ (UTM) projection
A specific implementation of the Mercator projection, designed for use around the world.
Box 1: ~ System.
The ~ (UTM) system is frequently used for recording coordinates of features in vector-based GISs, and cells of raster-based GISs are frequently aligned along the UTM grid.
In ~, Earth is divided into 60 zones limited by meridians, spanning six degrees of longitude each. Each zone is then projected using transverse Mercator with the central meridian of the zone as tangent meridian.
A particular subset of the transverse Mercator is the ~ (UTM) which was adopted originally by the US Army for large-scale military maps.
A point locating coordinate system based on the Transverse Mercator projection in which the world is divided into 60 zones of 6° longitude. Each zone stretches from the latitudes of 84° north to 80° south and these are labeled 1-60.

UTM is the first of two projection based coordinate systems to be examined in this unit
UTM provides georeferencing at high levels of precision for the entire globe ...
The ~ projection and grid system was adopted by the U.S. Army in 1947 for designating rectangular coordinates on large scale military maps. UTM is currently used by the United States and NATO armed forces.
The ~ System uses a two-dimensional grid for find location of the Earth's surface. It is also based on the Transverse Mercator map projection.
The ~ system does just this. The world is divided into 60 zones of latitude, each 6o wide, that extend from 84o N to 80o S. These zones begin at 180o longitude and are numbered consecutively eastward. The continental United States is covered by 10 UTM grid zones.
UTM ~. A projected coordinate system in meters that divides the globe into 60 zones. Louisiana falls into two UTM zones, Zone 15 which includes most of Louisiana (west) and Zone 16 which is east of 90 degrees longitude.
The ~ (UTM) projection is used to define horizontal, positions world-wide by dividing the surface of the Earth into 6 degree zones, each mapped by the Transverse Mercator projection with a central meridian in the center of the zone.
The ~ (UTM) system is a planar projection where degrees of longitude and latitude form a rectangular grid. Since distortion tends to increase most markedly on either side of the central meridian with this projection, UTM is used for narrow north-south oriented zones.
UTM (~) - A coordinate system based on the Transverse Mercator projection. The UTM grid extends North-south from 84oN to 80oS latitude. It is divided at the 180o meridian eastward into 60 6-degree zones.

The State Plane Coordinate System (SPCS) is a projected coordinate system that divides the U.S. and its possessions into over 120 zones (see Figure 3.6). Some smaller states use a single zone while larger states are divided into several zones.
~ (UTM)~. A projected coordinate system which defines a location on earth relative to a 60-zone grid system. Locations are defined relative to the WGS84 reference ellipsoid.
feet, then the projection is almost always the offical state plane coordinate system for the specific place. If the units are meters, then we still may have a State Plane Coordinate System, or it may be something else. In the latter case, the place-appropriate zone ~ ...

It took another 200 years for the next development in take place forthe Mercator projection.

When superimposed on a map, it usually carries the name of the projection used for the map- that is, Lambert grid, transverse Mercator grid, ~ grid.
~ [UTM] meters or State Plane feet). Tics are used to register map sheets when they are mounted on a digitizer and to transform the coordinates of a coverage (e.g., from digitizer units [inches] to UTM meters).
75 minute of longitude, at a scale of 1:12,000 cast on the ~ projection based on the North American Datum of 1983. Each image also has between 50 and 300 meters of overedge to facilitate tonal matching for mosaicking of adjacent images.
5 minute USGS topographic quadrangles (USGS quads) were used to rectify the October 5, 1990 SPOT-XS image to a ~ (UTM) map projection (RMSE = 0.29 pixels / 5.91 m). The 'slave' image was similarly rectified using GCPs obtained from the 1990 rectified image (1990 RMSE = 0.
The Military Grid Reference System (MGRS) is a grid-based system used to represent locations on the ~ (UTM) and universal polar stereographic (UPS) grid systems, expressed as an alphanumeric string.
The variable-location and variable-length nature of profiles stems mainly from the use of the UTM (~) ground reference system.
The position information in a Magellan GPS receiver may be displayed as longitudeAatitude, ~, Military Grid or other system coordinates.
UTM - Acronym for ~. A projected coordinate system that divides the world into 60 north and south zones, 6 degrees wide.
The familiar ~ (UTM) coordinates represent E-W and N-S movements in meters along the plane. The rub is that UTM zones are need to break the curved earth surface into a series of small flat, projected subsections that are difficult to edge-match.
There is a discussion about the ~ because of its use by the National Mapping Council in Australia. Some definitions are included, such as of the poles, equator, latitude and longitude, great circles, etc., but there is little available on projections themselves.
The best known use of the transverse Mercator projection is the specialized form called ~ (UTM) projection system.
Several of the more popular projections are: State Plane Coordinates (SPC) which uses feet for units of measure; ~ (UTM) which uses meters for units of measure; and latitude and longitude which uses degrees, minutes, and seconds of arc for units of measure.
Source maps are georeferenced to the surface of the earth, fit to the ~ (UTM) projection, and scanned at a minimum resolution of 250 dpi. The accuracy and datum of a DRG matches the accuracy and datum of the source map. [Category=Geospatial ] ...
This is fixed to points on the earth's surface which move over time because of changes in the earth's crust. A significant global projection system is ~ (UTM).

At these distances, slight errors will begin to compound and may create noticeable discrepancies. In particular, projects whose length crosses over coordinate systems zones (e.g., ~ [UTM] zones or State Plane zones) are likely to suffer from unacceptable grid-to-ground ...
