projection Definition

a systematic presentation of intersecting coordinate lines on a flat surface upon which features from a curved surface (as of the earth or the celestial sphere) may be mapped

the process or technique of reproducing a spatial object upon a plane or curved surface or a line by projecting its points; also : a graph or figure so formed

a transforming change

a booth in a theater or hall for housing and operating a projector and especially a motion-picture projector

a map projection of the surface of the earth so centered at any given point that a straight line radiating from the center to any other point represents the shortest distance and can be measured to scale

a conformal map projection of which the meridians are usually drawn parallel to each other and the parallels of latitude are straight lines whose distance from each other increases with their distance from the equator

projection of a single view of an object (such as a view of the front) onto a drawing surface in which the lines of projection are perpendicular to the drawing surface

the representation of related views of an object as if they were all in the same plane and projected by orthographic projection

a map projection consisting of a composite series of concentric cones each of which before being unrolled has been placed over a sphere so as to be tangent to a different parallel of latitude

a compromise map projection showing the poles as lines rather than points and more accurately portraying high latitude lands and water to land ratio

an equal-area map projection capable of showing the entire surface of the earth with all parallels as straight lines evenly spaced, the central meridian as one half the length of the equator, and all other meridians as curved lines

the ability of a person's spirit to travel to distant places
