Snake shot, rat shot, or dust shot, [1] more formally known as shotshell [2] (a name shared with the shotgun shell) or canister shot, refers to handgun and rifle cartridges loaded with lead shot canisters instead of bullets, intended for pest control (essentially small arms canister shot).
Robinson projection of the world The Robinson projection with Tissot's indicatrix of deformation Map of the world created by the Central Intelligence Agency, with standard parallels 38°N and 38°S. The Robinson projection is a map projection of a world map that shows the entire world at once. It was specifically created in an attempt to find a ...
Equirectangular projection of the world; the standard parallel is the equator (plate carrée projection). Equirectangular projection with Tissot's indicatrix of deformation and with the standard parallels lying on the equator True-colour satellite image of Earth in equirectangular projection Height map of planet Earth at 2km per pixel, including oceanic bathymetry information, normalized as 8 ...
Cassini projection of the world Cassini projection with 1,000 km indicatrices Cassini projection of the world modeled as a highly oblate ellipsoid with flattening 1:2 (= eccentricity √ 3 ⁄ 2) The Cassini projection (also sometimes known as the Cassini–Soldner projection or Soldner projection [ 1 ] ) is a map projection first described in ...
By a different metric, Capek's "Q", the Winkel tripel ranked ninth among a hundred map projections of the world, behind the common Eckert IV projection and Robinson projections. [ 6 ] In 1998, the Winkel tripel projection replaced the Robinson projection as the standard projection for world maps made by the National Geographic Society . [ 3 ]
However, if the map is marked with an accurate and finely spaced latitude scale from which the latitude may be read directly—as is the case for the Mercator 1569 world map (sheets 3, 9, 15) and all subsequent nautical charts—the meridian distance between two latitudes φ 1 and φ 2 is simply
A world map is a map of most or all of the surface of Earth. World maps, because of their scale, must deal with the problem of projection. Maps rendered in two dimensions by necessity distort the display of the three-dimensional surface of the Earth. While this is true of any map, these distortions reach extremes in a world map.
A Marsden Square map. Marsden square mapping or Marsden squares is a system that divides a world map with latitude-longitude gridlines (e.g. plate carrée projection, Mercator or other) between 80°N and 70°S latitudes (or 90°N and 80°S) into grid cells of 10° latitude by 10° longitude, each with a geocode, a unique numeric identifier.
