Snyder, 1993, pp. 5–8, ISBN 0-226-76747-7.〕 The projection maps meridians to vertical straight lines of constant spacing (for meridional intervals of constant spacing), and circles of latitude to horizontal straight lines of constant spacing (for constant intervals of parallels). The projection is neither equal area nor conformal. Because of the distortions introduced by this projection, it has little use in navigation or cadastral mapping and finds its main use in thematic mapping. In particular, the plate carrée has become a standard for global raster datasets, such as Celestia and NASA World Wind, because of the particularly simple relationship between the position of an image pixel on the map and its corresponding geographic location on Earth. ==Definition== Given a spherical model, :$\backslash begin$ x &= \lambda \cos \varphi_1\\ y &= \varphi \end where :$\backslash scriptstyle\backslash lambda$ is the longitude; :$\backslash scriptstyle\backslash varphi$ is the latitude; :$\backslash scriptstyle\backslash varphi\_1$ are the standard parallels (north and south of the equator) where the scale of the projection is true; :$x$ is the horizontal position along the map; :$y$ is the vertical position along the map. The point (0,0) is at the center of the resulting projection. The フランス語:plate carrée (French, for ''square plate''), is the special case where $\backslash scriptstyle\backslash varphi\_1$ is zero. This projection maps $x$ to be the value of the longitude and $y$ to be the value of the latitude, and therefore is sometimes called the latitude/longitude or lat/lon(g) projection or is said (erroneously) to be “unprojected”. While a projection with equally spaced parallels is possible for an ellipsoidal model, it would no longer be equidistant because the distance between parallels on an ellipsoid is not constant. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Equirectangular projection」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
