Are there 120 UTM zones?
UTM zones are six degrees wide. Each zone exists in a North and South variant. Universal Transverse Mercator Zone n (N) – The Northern Hemisphere projections for the infamous UTM system consisting of 120 zones (60 different zones with North and South variants of each).
Which areas are not covered by the UTM system?
The Universal Transverse Mercator system is not really universal, but it does cover nearly the entire Earth surface. Only polar areas–latitudes higher than 84° North and 80° South–are excluded.
What is difference between UTM and TM?
Lion’s share of offshore surveys is carried out in Universal Transverse Mercator projection (UTM). As opposed to TM, in UTM the cylinder is secant to the surface; it intersects the globe creating two standard meridians 180km away of the central meridian.
How many zones are there in the UTM system?
The UTM system consists of 60 zones, each 6-degrees of longitude in width. The zones are numbered 1-60, beginning at 180-degrees longitude and increasing to the east. The military uses their own implementation of the UTM system, called the Military Grid Reference System (MGRS). One system is no more or less accurate than the other.
Where is the UTM grid in the United States?
The USGS is one of the world’s largest providers of remote sensing data, employing the best tools and techniques to expand our knowledge of the Earth. The Universal Transverse Mercator grid that covers the conterminous 48 United States comprises 10 zones—from Zone 10 on the west coast through Zone 19 in New England.
How is the Universal Transverse Mercator ( UTM ) coordinate system used?
The Universal Transverse Mercator (UTM) coordinate system is a grid-based method of specifying locations on the surface of the Earth that is a practical application of a 2-dimensional Cartesian coordinate system. It is used to identify locations on the earth, but differs from the traditional method of latitude and longitude in several respects.
What is the maximum northing value of the UTM?
The maximum “northing” value is about 9 300 000 meters at latitude 84 degrees North, the north end of the UTM zones. In the southern hemisphere northings decrease southward from the equator to about 1 100 000 meters at 80 degrees South, the south end of the UTM zones.
