Where is the origin of UTM?

Where is the origin of UTM?

Where is the coordinate system origin? The natural origin of a UTM zone is the intersection of its central meridian with the equator, but this origin would assign negative coordinates to some locations. To avoid this, false easting and northing values are applied.

Where is the false origin for any UTM zone?

By definition, both origins are located 500,000 meters west of the central meridian of the zone (in other words, the easting of the central meridian is always 500,000 meters E). These are considered “false” origins since they are located outside the zones to which they refer.

When was UTM invented?

1947
The Universal Transverse Mercator 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.

How many UTM projections are there?

60
DMAP: UTM Grid Zones of the World. There are 60 longitudinal projection zones numbered 1 to 60 starting at 180°W. Each of these zones is 6 degrees wide, apart from a few exceptions around Norway and Svalbard.

What projection is UTM?

Universal Transverse Mercator
UTM is the acronym for Universal Transverse Mercator, a plane coordinate grid system named for the map projection on which it is based (Transverse Mercator). The UTM system consists of 60 zones, each 6-degrees of longitude in width.

Where is the origin of the UTM zone?

With UTM zones xx of EPSG 326xx (UTM zone xx North WGS84), this shift is 500000 m. The role of the shift is to avoid negative X coordinates. Consequently, the lat/long coordinate of the origin of this UTM zone is located approximately 4°30′ West from the center of projection.

How many variations on the UTM projection are there?

Fifty-nine variations on this projection are used to minimize distortion in the other 59 UTM zones. In every case, distortion is no greater than 1 part in 1,000. This means that a 1,000 meter distance measured anywhere within a UTM zone will be no worse than + or – 1 meter off.

How is the UTM based on the Transverse Mercator projection?

UTM Projection. As the name suggests, the Universal Transverse Mercator projection is based on the cylindrical Transverse Mercator projection. The cylinder in the Transverse Mercator projection is tangent along a meridian (line of longitude) or it is secant, in which case it cuts through the earth at two standard meridians.

How many degrees of longitude does the UTM have?

The projection from spheroid to a UTM zone is some parameterization of the transverse Mercator projection. The parameters vary by nation or region or mapping system. Most zones in UTM span 6 degrees of longitude, and each has a designated central meridian.
