SRS Ontology: Geoprojection

An azimuthal minimum error projection for the region within the small or great circle defined by an angular distance, from the tangency point of the plane

A modified azimuthal projection whose graticule takes the form of an ellipse

A projection in which every angle between two curves that crosss each other on a celestical body is preserved in the image of the projection

In this projection, the radial scale is adjusted so that areas are everywhere correctly represented. The only consideration, therefore, is that areas shall be strictly comparable over the entire projection. In the process of adjustment, shape and distance may both become distorded. (ref. George P. Kellaway, Map projections. Methuen &co Ltd. London, UK, 1970.)

In this projection, the radial scale is adjusted so that every point on the projection lies at its correct distance from the center of the plane. The scale along the meridians that is, radially from the center, is everywhere correct and it is in respect of this propperty that the projection is said to be equidistant.(ref. George P. Kellaway, Map projections. Methuen &co Ltd. London, UK, 1970.)

In this class of projection, the parallels and the meridians of the ‘generating’ globe are projected geometrically from a point on to a plane, which is tangential to the globe, and at right angles to the line joining the point of origin to the point of contact. (ref. George P. Kellaway, Map projections. Methuen &co Ltd. London, UK, 1970.)

The Bolshoi Sovietskii Atlas Mira Projection is a perspective projection from a point on the Equator opposite a given meridian onto a cylinder secant at the 30º parallels. (Ref: https://www.mathworks.com/help/map/bsam.html)

A cylindrical equal-area projection that uses a standard parallel of phi_s=50 degrees

A cylindrical equal-area map projection with standard parallels set at 30° north and south

A map projection first described in an approximate form by César-François Cassini de Thury in 1745. It is an example of the transverse application of the Plate Carrée projection ; that is the cylinder may be regarded as touching the globe along the great circle formed by two selected opposite meridians. (ref. George P. Kellaway, Map projections. Methuen &co Ltd. London, UK, 1970.)

The central cylindrical projection is a perspective cylindrical map projection. It corresponds to projecting the Earth's surface onto a cylinder tangent to the equator as if from a light source at Earth's center. The cylinder is then cut along one of the projected meridians and unrolled into a flat map. (Ref: https://en.wikipedia.org/wiki/Central_cylindrical_projection)

An equal-area pseudocylindrical projection that maps the sphere onto a triangle or diamond

Compromise projections give up the idea of perfectly preserving metric properties, seeking instead to strike a balance between distortions, or to simply make things look right. (Ref: https://en.wikipedia.org/wiki/Map_projection)

In cartography, a conformal map projection is one in which every angle between two curves that cross each other on Earth is preserved in the image of the projection. (Ref: https://en.wikipedia.org/wiki/Conformal_map_projection)

Projections of this class can be visualized as made on a cone, which is afterwards opened out flat. (ref. George P. Kellaway, Map projections. Methuen &co Ltd. London, UK, 1970.)

A map projection which has a cylindrical projection surface and where two areas in the map have the same relative size compared to their size on the sphere. (Ref: https://en.wikipedia.org/wiki/Cylindrical_equal-area_projection)

Projections in this class can be visualized as made in a cynlinder, which is the cut along a convenient line parallel to the axis, and opened out flat. (ref. George P. Kellaway, Map projections. Methuen &co Ltd. London, UK, 1970. See also : https://en.wikipedia.org/wiki/Map_projection#Normal_cylindrical_projection)

The stereographic projections are perspective projections, projecting the sphere onto a cylinder in the direction of the antipodal point on the equator. The cylinder crosses the sphere at two standard parallels, equidistant from the equator. (Ref : https://www.pygmt.org/v0.4.0/projections/cyl/cyl_stereographic.html)

In cartography, an equivalent, authalic, or equal-area projection is a map projection that preserves relative area measure between any and all map regions. (Ref : https://en.wikipedia.org/wiki/Equal-area_projection)

The equidistant cylindrical projection maps meridians to vertical straight lines of constant spacing (for meridional intervals of constant spacing), and circles of latitude to horizontal straight lines of constant spacing (for constant intervals of parallels). (Ref : https://en.wikipedia.org/wiki/Equirectangular_projection)

An equidistant projection is a map projection that maintains scale along one or more lines, or from one or two points to all other points on the map. The distance between the center point of the map and any other point is correct with an equidistant projection. (Ref: https://www.caliper.com/glossary/what-is-an-equidistant-projection.htm?srsltid=AfmBOorB2RI2pbhjDnDz5ltbPX2wqDRoNRgMe1Gbe99tc8W9j-zuyV2E)

The equirectangular projection maps meridians to vertical straight lines of constant spacing (for meridional intervals of constant spacing), and circles of latitude to horizontal straight lines of constant spacing (for constant intervals of parallels). (Ref: https://en.wikipedia.org/wiki/Equirectangular_projection)

In this projection the cylinder may be regarded as intersecting the globe along the parallels of latitude 45°N and 45°S. The projection is the made stereographically, which represent a section through the center of the globe at richt angles to the plane of the equator. (ref. George P. Kellaway, Map projections. Methuen &co Ltd. London, UK, 1970.) (See also : https://en.wikipedia.org/wiki/Gall_stereographic_projection)

The projection is made from the center of the globe onto a plane which is tangential to the generating globe. When the plane is tangential at either of the two poles, the resulting projection is referred to as the polar case ; when the plane is tangential at some point on the equator, as the equatorail case ; when the plane is tangential elsewhere, as the oblique case. (ref. George P. Kellaway, Map projections. Methuen &co Ltd. London, UK, 1970.)

This is an equal-area projection. Scale is true along 40º42'N and 38º27'S, and is constant along any parallel but generally not between pairs of parallels equidistant from the Equator. It is free of distortion only along the central meridian at 40º42'N and 38º27'S. (Ref: https://www.mathworks.com/help/map/hatano.html)

The Lambert azimuthal equal-area projection is a particular mapping from a sphere to a disk. It accurately represents area in all regions of the sphere, but it does not accurately represent angles. (Ref: https://en.wikipedia.org/wiki/Lambert_azimuthal_equal-area_projection)

A cylindrical projection where the cylinder touches the globe along the equator. The projection is performed so that the area of surface of the globe intercepted between the plane of the equator and its parallel plane going through some point P at the surface of the globe is equal to the area of the surface of the culinder intercepted between the same planes. (ref. George P. Kellaway, Map projections. Methuen &co Ltd. London, UK, 1970.)

This is a simple non perspective cylindrical projection. The equator is projected as a straight line, of correct length, and accurately divided for the points of intersection with the meridians, which are projected as straight lines, also of correct lentgh and perpendicular to the equator. The meridians are correctly divided for the points of intersection with the parallels, which are therefore straight lines, parallel to the equator. (ref. George P. Kellaway, Map projections. Methuen &co Ltd. London, UK, 1970.)

All parallels of latitude are projected equal in length to the equator of the generating globle. The scale along the equator is therefore true, but away from the equator, the scale long the parallels is exaggerated. (ref. George P. Kellaway, Map projections. Methuen &co Ltd. London, UK, 1970.)

A pseudocylindrical map projection designed by Tom Patterson and introduced in 2008

The Oblique Equal Area Cylindrical projection represents an orthographic projection of an ellipsoid onto a cylinder. It is similar to the Equal Area Cylindrical 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. (Ref: https://www.bluemarblegeo.com/knowledgebase/calculator/projections/Oblique_Equal_Area_Cylindrical.htm)

The oblique Mercator projection is the oblique aspect of the standard (or Normal) Mercator projection. The cylinder axis is neither the polar axis nor in the plane of the equator. (Ref: https://en.wikipedia.org/wiki/Oblique_Mercator_projection)

Oblique Plate Carree Projection is the oblique aspect of the Plate Carree Projection: the cylinder axis is neither the polar axis nor in the equatorial plane. (Ref: https://www.mapthematics.com/ProjectionsList.php?Projection=55)

A planar or cylindrical projection whose point of tangency is neither on the equator nor at a pole. A conic projection whose axis does not line up with the polar axis of the globe. (Ref: https://support.esri.com/en-us/gis-dictionary/oblique-projection)

An azimuthal, conformal, polyconic (general) perspective projection that is visually similar to the ordinary Stereographic. (Ref: https://manifold.net/doc/mfd9/double_stereographic_projection.htm)

The point of origin is at infinity , and the plane of projection is tangential in any desired position ; so polar, equatorial and oblique case are all possible. The resulting projection is, as it were, a photographic view of a distant globe. (ref. George P. Kellaway, Map projections. Methuen &co Ltd. London, UK, 1970.)

This is a simple non perspective cylindrical projection. The equator is projected as a straight line, of correct length, and accurately divided for the points of intersection with the meridians, which are projected as straight lines, also of correct lentgh and perpendicular to the equator. The meridians are correctly divided for the points of intersection with the parallels, which are therefore straight lines, parallel to the equator. (ref. George P. Kellaway, Map projections. Methuen &co Ltd. London, UK, 1970.)

The projection is made from the end of the diameter which is opposite the point of contact of the plane of projection ; so polar, equatorial and oblique case are all possible. (ref. George P. Kellaway, Map projections. Methuen &co Ltd. London, UK, 1970.)

The transverse cylindrical equal-area is a transverse aspect of the cylindrical equal-area projection. (Ref: https://pro.arcgis.com/en/pro-app/latest/help/mapping/properties/transverse-cylindrical-equal-area.htm#:~:text=Sources-,Description,was%20presented%20by%20Johann%20H.)

A Mercator projection which is made transverse, that is the cylinder is regarded as touching the globe along the great circle formed by two selected opposite meridians. (ref. George P. Kellaway, Map projections. Methuen &co Ltd. London, UK, 1970.)

The Universal Transverse Mercator (UTM) is a map projection system for assigning coordinates to locations on the surface of the Earth. However, it differs from global latitude/longitude in that it divides earth into 60 zones and projects each to the plane as a basis for its coordinates. Specifying a location means specifying the zone and the x, y coordinate in that plane. 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. (Ref: https://en.wikipedia.org/wiki/Universal_Transverse_Mercator_coordinate_system)
