Scale. Only two meridians, exactly 180° apart, can be projected as straight lines, crossing the poles. ESRI separates these two case by appending "Natural_Origin" (for the "Hotine_Oblique_Mercator") and "Center" (for the "Oblique_Mercator") to the projection names. Developed for conformal mapping of areas that are obliquely oriented and do not follow a north–south or east–west trend. Laborde oblique Mercator is an oblique cylindrical projection. Space Oblique Mercator maps show a satellite's groundtrack as a curved line that is continuously true to scale as orbiting continues. Similar projections. Oblique Mercator Azimuth. When paired with a suitable geodetic datum, the oblique Mercator delivers high accuracy in zones less than a few degrees in arbitrary directional extent. Usage. public class ObliqueMercatorProjection extends CylindricalProjection. Only a single form of each projection type is used for the entire SPCS. It is similar to the Mercator projection, except that the cylinder is wrapped around the ellipsoid so that it touches the surface along the great circle path chosen for … Other OR LDP's work with Carlson. Synonyms for Oblique Mercator projection in Free Thesaurus. Physical World Wall Map - Miller Projection Starting at … The Oblique Mercator projection is a cylindrical, conformal map projection. To continually map the Earth’s surface using Landsat data, an entirely new projection had to be created. ... World maps in numerous American atlases and some other atlases, as a projection resembling the Mercator but having less distortion of area and scale, especially near the poles. It is used for conformal mapping of areas that are obliquely oriented and do not follow a north–south or east–west trend. Groud Control Using Space Oblique Mercator Projection Theory." Used for spatial data presentation for whole state. Space-oblique Mercator projection is a map projection devised in the 1970s for preparing maps from Earth-survey satellite data. Distances are accurate along the central line if the scale factor is 1.0. It is particularly useful when mapping regions of large lateral extent in an oblique direction. Choose Options. Bernhard Jenny, 23 September 2010: changed super class to Cylindrical A conformal cylindrical map projection in which points on the surface of a sphere or spheroid, such as the earth, are conceived as developed by Mercator principles on a cylinder tangent along an oblique great circle. The parameters of this map projection have been carefully chosen so that the inevitable distortion that occurs is relegated to the oceans and to the least populated and least recognizable land masses. Starting at $29.95. This a low distortion projection( LDP), grid distance = ground distance for practical purposes, using an Oblique Mercator Projection, NAD83. They share the same underlying mathematical construction and consequently the oblique Mercator inherits many traits from the normal Mercator: There is different ways to specify the projection parameters: SPCS2022 is limited to the following three conformal projections: Lambert Conformal Conic, Transverse Mercator, and Oblique Mercator. Oblique Mercator Projection algorithm is taken from the USGS PROJ package. Lines of constant compass heading (called rhumb lines by sailors) are straight lines on this map. The projection of Mercator is a cylindrical cartographic projection that represents the whole terrestrial surface. The Oblique Mercator projection can be seen as a generalization of Mercator and Transverse­Mercator projections when the central line is not along the equator or a meridian, respectively. Only two meridians, exactly 180° apart, can be projected as straight lines, crossing the poles. It is a generalization of the oblique Mercator projection that incorporates the time evolution of a given satellite ground track to … It is similar to the Mercator projection, except that the cylinder is wrapped around the ellipsoid so that it touches the surface along the great circle path chosen for the central line, instead of along the earth's equator. 1 synonym for Mercator projection: Mercator's projection. It does not maintain true directions, but angles and shapes are maintained at infinitesimal scale. It is particularly useful when mapping regions of large lateral extent in an oblique direction. A large-scale (1:24,000) 7.5-minute USGS Topographic Map based on the Transverse Mercator projection is nearly correct in every respect. Planar (Orthographic) Different orthographic projection parameters: ... (Type 1), or the standard lines of the transverse and oblique aspects (Types 2 and 3). This class covers also the Rectified Skew Orthomorphic (RSO) case.. The central point defined by the Center Latitude and Center Longitude is approximately in the middle of the North American and South American landmasses near the Isthmus of Panama. World Physical Satellite Image Map - Oblique Mercator Projection. The property of the Mercator projection map that made it useful to navigators is that it preserves angles. RE: Oblique Mercator - Added by Jason over 5 years ago Its been a few years since I did this, but if I interpret my old scripts correctly, this is what worked for me with GMT v4.5.x (seems to still work with GMT v5.1.2). Krovak. The map is thereby conformal. The Oblique Mercator projection uses a (U, V) coordinate system, with the U axis along the central line. Need to set a user-defined projection into Carlson 2014. For example, the illustration at the beginning of this topic was created using Oblique Mercator (B, centered) using Center Latitude 0 (the Equator), Center Longitude -90 and a Center Line Azimuth of -30.

Both poles are presented as a point inside the projection outline. The Oblique Mercator (B, centered) version is conceptually easiest for many people. Oblique configurations of the cylinder give rise to the oblique Mercator projection. It is similar to the Mercator projection, except that the cylinder is wrapped around the sphere so that it touches the surface along the great circle path chosen for the central line, instead of along the earth's equator. 2. The graticule in this example was originally created in a latitude / longitude drawing for the region near North and South America. In general, the meridians and parallels are projected as complex curves. bridge This new projection was created by John Parr Snyder and is known as the Space Oblique Mercator (SOM) projection.

It was developed by Gerardus Mercator in the sixteenth century, in the year 1569. Conformality retains equal scale locally in all directions and pre- serves angular relationships. The Mercator projection was invented by Gerardus Mercator, a Flemish mapmaker. This projection has been referred to as, “one of the most complex projections ever devised” by Library of Congress cartographic historian, John W. Hessler. Both parallels and meridians are complex curves. World Satellite Image Map - Oblique Mercator Projection - Enhanced Physical. The Mercator projection is a cylindrical map projection presented by Flemish geographer and cartographer Gerardus Mercator in 1569. In general, the meridians and parallels are projected as complex curves. The Hotine Oblique Mercator (HOM) projection is a cylindrical, conformal map projection. It is a generalization of the oblique Mercator projection that incorporates the time evolution of a given satellite ground track to optimize its representation on the map. Scale variations within the oval-shaped region covered are less than variations on standard conformal projections, such as an oblique Mercator or oblique Stereographic projection. Space Oblique Mercator A unique and specialized projection is the Space Oblique Mercator (SOM) projection. This is an oblique rotation of the Mercator projection developed for conformal mapping of areas that do not follow a north–south or east–west orientation but are obliquely oriented. Hotine oblique Mercator is a conformal map projection. The projection types correspond to specific computation algorithms used by NGS. This stunningly detailed satellite image map of the world features both land cover and bathymetric data depicted in an Oblique Mercator Projection. SPACE OBLIQUE MERCATOR formality as dominant. To learn more about the creation of the SOM projection, refer to “Projecting Time: John Parr Snyder and the Development of the Space Oblique Mercator Projection” by John W. Hessler. The Mercator and the Transverse Mercator projections are both limiting forms of the Oblique Mercator: The Mercator projection is equivalent to an Oblique Mercator with central line along the Equator, while the Transverse Mercator is equivalent to an Oblique Mercator with central line along a meridian. 6.3.4 Oblique Mercator (-Jo-JO) Next: 6.1 Conic Projections Up: The Generic Mapping Tools Previous: 5.2 Linear Projection with Contents Index Paul Wessel 2004-10-01 Projection’s formulas … The most common cylindrical projection is the Mercator projection, which is the basis of the UTM (Universal Transverse Mercator) system. Specify the Center Line Azimuth to be the bearing line that runs in the approximate line of the main features of the map. This projection has been referred to as, “one of the most complex projections ever devised” by Library of Congress cartographic historian, John W. Hessler. Both parallels and meridians are complex curves. 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. Such a projection is needed for the continuous mapping of satellite images, but it is useful only for a relatively narrow band along the groundtrack. After projection into Oblique Mercator (B, centered) those portions of the graticule not reasonably near the central line of the projection were very distorted. The Oblique Mercator projection is a cylindrical, conformal map projection. An azimuth of -30 is approximately the angle made drawn through the center of masses of North and South America. It became the standard map projection for navigation because it is unique in representing north as up and south as down everywhere while preserving local directions and shapes. Extent of the map is defined by orbit of the satellite. small-scale Mercator map of the world disappears almost completely on a properly oriented large-scale Transverse Mercator map of a small area in the same high latitudes. The Hotine Oblique Mercator (HOM) projection is a cylindrical, conformal map projection. Also known as oblique cylindrical orthomorphic, this is an oblique rotation of the Mercator projection. The conformal cylindrical projection was conceived by Mercator and in this application is defined in Space; it is Oblique to the polar axis. 6.3.4 Oblique Mercator (-Jo-JO) Oblique configurations of the cylinder give rise to the oblique Mercator projection. They were selected and deleted by hand. The most common cylindrical projection is the Mercator projection, which is the basis of the UTM (Universal Transverse Mercator) system. bridge Learn more about the Mercator projection Centered versions unproject 0,0 to the center of the projection, while non-centered versions unproject 0,0 to the intersection of the Equator and the Prime Meridian. Hotine oblique Mercator is an oblique cylindric projection. This inflation is very small near th… The Oblique Mercator for the sphere is equivalent to a regular Mercator projection that has been altered by wrapping a cylinder around the sphere so that it touches the surface along the great circle path chosen for the central line instead of along the Earth's Equator. The Oblique Mercator (EPSG code 9815) is the same, except the grid coordinates begin at the central point (where the latitude of center and central line intersect). Used for an area that can be contained within an oval shape to minimize the scale distortions in … Oblique Mercator Projection algorithm is taken from the USGS PROJ package. As a side effect, the Mercator projection inflates the size of objects away from the equator. Starting at $29.95. The oblique Mercator map projection is an adaptation of the standard Mercator projection.The oblique version is sometimes used in national mapping systems.

Defini- tion of the projection is given in nonrigorous It is similar to the Mercator projection, except that the cylinder is wrapped around the sphere so that it touches the surface along the great circle path chosen for the central line, instead of along the earth's equator. Has anyone successfully implemented the Oregon coordinate Reference System's 'Columbia River West Zone'. Space-oblique Mercator projection is a map projection devised in the 1970s for preparing maps from Earth-survey satellite data. The Space Oblique Mercator projection, the Conformal Space Projection (CSP) (Cheng 1996) and other space map projections have all been designed specifically for satellite imagery that is scanned around a nadir ground track, such as SPOT and Landsat imagery. This map projection was developed fairly recently, in 1976, for the specific purpose of mapping of imagery from an orbiting satellite around the ellipsoidal Earth and is completely free of distortion along the path of the satellite. This new projection was created by John Parr Snyder and is known as the Space Oblique Mercator (SOM) projection. EPSG:3078 Projected coordinate system for United States (USA) - Michigan. For applications with an accuracy of better than 1m, replaced by NAD83(HARN) / Michigan Oblique Mercator.
