A map projection is a systematic transformation of the latitudes and longitudes of locations on the surface of a sphere or an ellipsoid into locations on a plane. Map projections are necessary for creating maps.
A map projection is any orderly system of parallels and meridians on which a map can be drawn. These parallels and meridians help take real world locations and spatial references and put them in a flat plane. Any mathematical function transforming coordinates from a curved surface to a plane is considered a projection. 1 Map projections are attempts to portray the surface of the earth or a portion of the earth on a flat surface. 2  Some distortions of conformality, distance, direction, scale, and area always result from this process. Noun. 1. map projection-a projection of the globe onto a flat map using a grid of lines of latitude and longitude. conformal projection, orthomorphic projection-a map projection in which a small area is rendered in its true shape. Commonly, a map projection is a systematic transformation of the latitudes and longitudes of locations on the surface of a sphere or an ellipsoid into locations on a plane. Map projections are necessary for creating maps. All map projections distort the surface in some fashion. conic projection, conical projection-a map projection of the globe onto a cone with its point over one of the earth's poles. equal-area map projection, equal-area projection-a map projection in which quadrilaterals formed by meridians and parallels have an area on the map proportional to their area on the globe. Mercator projection, Mercator's projection-a map projection of the earth onto a cylinder; areas appear greater the farther they are from the equator. projection-the representation of a figure or solid on a plane as it would look from a particular direction. 1  Facebook. It is a projection of a map. Additionally A map projection is used to represent all or part of the round Earth onto a flat surface which always creates some form of distorti … on. Mapmakers and mathematicians have devised countless ways to project the image of the globe onto paper.
