cylindrical equal-spaced projection
1Cylindrical equal-area projection — of the world; standard parallel at 40°N …
2cylindrical projections/cylindrical equal-area map projection — A cylindrical map projection onto a cylinder tangent to a sphere, showing the geographic meridians as a family of equal spaced parallel straight lines perpendicular to a second family of parallel straight lines. They represent the geographic… …
3Lambert 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… …
4Map 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 …
5Stereographic 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 …
6Equirectangular projection — The equirectangular projection (also called the equidistant cylindrical projection, geographic projection, plate carré or carte parallelogrammatique projection or CPP) is a very simple map projection attributed to Marinus of Tyre, who Ptolemy… …
7Scale (map) — The scale of a map is defined as the ratio of a distance on the map to the corresponding distance on the ground. If the region of the map is small enough for the curvature of the Earth to be neglected, then the scale may be taken as a constant… …
8Sundial — A sundial is a device that measures time by the position of the Sun. In common designs such as the horizontal sundial, the sun casts a shadow from its style (a thin rod or a sharp, straight edge) onto a flat surface marked with lines indicating… …
9HSL and HSV — Fig. 1. HSL (a–d) and HSV (e–h). Above (a, e): cut away 3D models of each. Below: two dimensional plots showing two of a model’s three parameters at once, holding the other constant: cylindrical shells (b, f) of constant saturation, in this case… …
10map — mappable, adj. mapper, n. /map/, n., v., mapped, mapping. n. 1. a representation, usually on a flat surface, as of the features of an area of the earth or a portion of the heavens, showing them in their respective forms, sizes, and relationships… …
