It is neither equal-area nor conformal but instead tries to balance the distortion inherent in any projection. ==Formulae== The projection is conventionally defined as:〔Snyder, Flattening the Earth, pp 109〕 $x\; =\; R\backslash lambda/\backslash sqrt\; 2$ $y\; =\; R\; (1+\backslash sqrt\; 2/2)\backslash tan\; \backslash frac$ where ''λ'' is the longitude from the central meridian in degrees, ''φ'' is the latitude, and ''R'' is the radius of the globe used as the model of the earth for projection. It is a perspective projection if the point of projection is allowed to vary with longitude: the point of projection being on the equator on the opposite side of the earth from the point being mapped and with the projective surface being a cylinder secant to the sphere at 45°N and 45°S.〔http://www.progonos.com/furuti/MapProj/Normal/ProjCyl/ProjCEA/projCEA.html#Braun accessed 20 April 2013〕 Gall called the projection "stereographic" because the spacing of the parallels is the same as the spacing of the parallels along the central meridian of the equatorial stereographic projection. 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「Gall stereographic 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.
