polar stereographic projection
1polar stereographic projection — A projection formed by positioning a flat sheet of paper tangential over one pole on the reduced earth and projecting the latitude and longitude graticule onto the paper from a light source positioned at the other pole. In this projection, the… …
2Stereographic projection — In geometry, the stereographic projection is a particular mapping (function) that projects a sphere onto a plane. The projection is defined on the entire sphere, except at one point mdash; the projection point. Where it is defined, the mapping is …
3Universal Polar Stereographic coordinate system — The Universal Polar Stereographic (UPS) coordinate system is used in conjunction with the Universal Transverse Mercator (UTM) coordinate system to locate positions on the surface of the earth. Like the UTM coordinate system, the UPS coordinate… …
4projection — projectional /preuh jek sheuh nl/, adj. /preuh jek sheuhn/, n. 1. a projecting or protruding part. 2. the state or fact of jutting out or protruding. 3. a causing to jut or protrude. 4. the act, process, or result of projecting. 5. Cartog. a… …
5Map projection — A medieval depiction of the Ecumene (1482, Johannes Schnitzer, engraver), constructed after the coordinates in Ptolemy s Geography and using his second map projection A map projection is any method of representing the surface of a sphere or other …
6Lambert azimuthal equal-area projection — 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. Intuitively, it gives a planar picture of the… …
7Collocation (remote sensing) — Collocation is a procedure used in remote sensing to match measurements from two or more different instruments. This is done for two main reasons: for validation purposes when comparing measurements of the same variable, and to relate… …
8Primitive equations — The primitive equations are a set of nonlinear differential equations that are used to approximate global atmospheric flow and are used in most atmospheric models. They consist of three main sets of equations: # Conservation of momentum :… …
93-sphere — Stereographic projection of the hypersphere s parallels (red), meridians (blue) and hypermeridians (green). Because this projection is conformal, the curves intersect each other orthogonally (in the yellow points) as in 4D. All curves are circles …
10Geographic coordinate system — Map of Earth showing lines of latitude (horizontally) and longitude (vertically), Eckert VI projection; large version (pdf, 3.12MB) …
