The projection changes only the central meridian per zone. One of the widely and familiar used Mercator projection is the cylindrical projection. A map projection refers to any mathematical transformation of the globe onto some other surface, including many, which cannot be physically realized by any actual optical projection system. The globe is divided into 60 north and south zones, each spanning 6° of longitude. The parameters needed to convert to or from UTM Zone 15 are shown below. The "UTM Zone" is a shorthand These parameters are constant for a projection. 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). X … Red labels denote irregular zones. (Polar coordinate systems are used to specify positions beyond these latitudes.) When specifying a Universal Transverse Mercator projection for a terrain image layer, your terrain image files must be aligned with false (projected) north towards the top of the image, and false east to the right of the image. Viele übersetzte Beispielsätze mit "Universal transverse Mercator projection" – Deutsch-Englisch Wörterbuch und Suchmaschine für Millionen von Deutsch-Übersetzungen. The projection of Mercator is a cylindrical cartographic projection that represents the whole terrestrial surface. It has become the most used because it allows precise measurements in meters to within 1 meter. UTM ARC/INFO Example. Das UTM-System (von englisch Universal Transverse Mercator) ist ein globales Koordinatensystem.Es teilt die Erdoberfläche (von 80° Süd bis 84° Nord) streifenförmig in 6° breite vertikale Zonen auf, die einzeln mit der jeweils günstigsten transversalen Mercator-Projektion verebnet und mit einem kartesischen Koordinatensystem überzogen werden. For example, the MnDOT Basemap specifies "Universal Transverse Mercator (UTM) Minnesota extended Zone 15, NAD83 coordinates." This cartographic projection has been heavily criticized for the fact that it distorts forms as it approaches the poles making the land masses look larger than they actually are. Universal Transverse Mercator zones on an equirectangular world map with major circles of latitude by CMG Lee. […] Figures 1 and 2 illustrate that the Mercator and Transverse Mercator … The UTM system is not a single map projection. However, in the transverse Mercator, the cylinder is rotated 90° (transverse) relative to the equator so that the projected surface is aligned to a central meridian rather than to the equator, as is the case with the equatorial Mercator projection. The Universal transverse Mercator (UTM) is a system that uses the ellipsoidal transverse Mercator as the foundation for each of 60 zones that cover most of the Earth. Various countries use this projection for their topographic maps and large-scale coordinate systems. Each zone is based on a specifically defined secant Transverse Mercator projection. Each different centerline defines a UTM Zone. UTM zones are six degrees wide. To understand how the projection works, imagine the Earth as an orange, with all geographical features and the parallels and meridians already drawn in. The UTM system consists of 60 zones, each 6-degrees of longitude in width. (The parameters are identical to MGA, therefore users often select UTM where MGA may not be an available option in their software or GNSS receiver setup menu). The zones are bounded by meridians 3° either side of a central meridian. • Longitude is divided into 60 zones each 6° wide. The Universal Transverse Mercator system is not really universal, but it does cover nearly the entire Earth surface. The transverse Mercator projection is an adaptation of the Mercator projection.Both projections are cylindrical and conformal. Many translated example sentences containing "Universal Transverse Mercator projection" – French-English dictionary and search engine for French translations. The standard international coordinate projection system used with many different map datums. The Universal Transverse Mercator system of projections deals with this by defining 60 different standard projections, each one of which is a different Transverse Mercator projection that is slightly rotated to use a different meridian as the central line of tangency. It was developed by Gerardus Mercator in the sixteenth century, in the year 1569. The Transverse Mercator was invented by Johann Lambert (1728-77) (Snyder, 1987, p. 48), even though it is named after Gerardus Mercator (1512-94). Note: The results of using the calculator provided on this page are believed to be accurate to 1 metre, but the accuracy is not in any way guaranteed. The best known transverse cylindrical projection is the Transverse Mercator. Toggle navigation NGS Home NGS_Description. Universal Transverse Mercator The UTM system applies the Transverse Mercator projection to mapping the world, using 60 pre-defined standard zones to supply parameters. 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. The units for both east and north coordinates are meters. GPS equipment, especially lower priced receivers, does not support the New Brunswick Double Stereographic Projection. The Universal Transverse Mercator Grid The National Imagery and Mapping Agency (NIMA) (formerly the Defense Mapping Agency) adopted a special grid for military use throughout the world called the Universal Transverse Mercator (UTM) grid. Basic Transverse Mercator 15 3.1 Definition of transverse Mercator 15 3.2 Given l, f , compute x, y 15 3.3 Notes to the developer 16 3.4 Forward mapping: a numerical example 17 3.5 Given x, y , compute l, f 17 3.6 Inverse mapping: a … The world is divided into 60 … Universal Transverse Mercator (UTM) Projection Refer to this post for background information on projections. Geographic to Transverse Mercator projection. … The UTM system is not a single map projection but instead a series of sixty zones. Transverse Mercator and UTM 3. ticular projection for which they are designed. is obtained by evaluating using . The Universal Transverse Mercator • The Gauss-Kruger version of the transverse mercator projection covers latitudes from 80°S to 84°N. The Universal Transverse Mercator (UTM) coordinate system is a specialized application of the transverse Mercator projection. In the UTM coordinate system a grid is used to specify locations on the surface of the Earth. As expected, the Northern Hemisphere is now on the left, and the Southern Hemisphere on the right. Universal transverse Mercator A Universal Transverse Mercator is an accurate projection in narrow zones. UTM zones are six degrees wide. Each zone exists in a North and South variant. Several additional parameters need to be computed before transformations can be undertaken (,,). A Transverse Mercator projection of the world, using a physical map as the input. Transverse Mercator to geographic. Universal Transverse Mercator (UTM) system is a specialized application of the Transverse Mercator projection. The military uses their own implementation of the UTM Each zone has its own central meridian. Europeans can best understand UTM by thinking of it as a world-wide version of the Gauss Kruger system, which is also based on a regular … UTM - Universal Transverse Mercator Geographic Coordinate System. Gauss-Krüger coordinate systems and the Universal Transverse Mercator (UTM) coordinate system are based on this projection while the State Plane Coordinate System uses it for all north-south zones. Universal Transverse Mercator (UTM) The UTM system applies the Transverse Mercator projection to mapping the world, using 60 pre-defined standard zones to supply parameters. For the Universal Transverse Mercator System, the globe is divided into 60 zones, each spanning six degrees of longitude. The Universal Transverse Mercator (UTM) projection is defined by eight parameters. New York City's zone is shown as an example. OVERVIEW----UTM coordinates are based on a family of 120 Transverse Mercator map projections (two for each UTM zone, with one for each N/S hemisphere).The earth is divided into 60 zones, each 6° wide in longitude (with the exception of a few non-standard-width zones for Svalbard and southwest of Norway). Universal Transverse Mercator Projections. Only polar areas--latitudes higher than 84° North and 80° South--are excluded. As the name suggests, UTM is a transverse projection type meaning that the developable surface axis intersects the earth’s axis at a perpendicular angle. La Transverse universelle de Mercator (en anglais Universal Transverse Mercator ou UTM) est un type de projection conforme de la surface de la Terre. 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. Skip to main content. The following parameters apply to all NAD27 UTM zones: Projection = Transverse Mercator Spheroid = Clarke 1866. Each zone has its own central meridian from which it spans 3 degrees west and 3 degrees east. Transverse Mercator Calculator A facility for converting latitude/longitude co-ordinates to co-ordinates in metres on a Transverse Mercator projection. Universal Transverse Mercator System Projection. UTM - Universal Transverse Mercator. The UTM Grid - Universal Transverse Mercator Projection. The zones are numbered 1-60, beginning at 180-degrees longitude and increasing to the east. Projection constants. Through their options settings, users can choose either spherical coordinates of Latitude / Longitude or Universal Transverse Mercator (UTM) for plane coordinates. 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. As the name suggests, the Universal Transverse Mercator projection is based on the cylindrical Transverse Mercator projection. Each zone exists in a North and South variant.
