Although named after Rigobert Bonne (1727–1795), the projection was in use prior to his birth, in 1511 by Sylvano, Honter in 1561, De l'Isle before 1700 and Coronelli in 1696. Both Sylvano and Honter’s usages were approximate, however, and it is not clear they intended to be the same projection.〔''Flattening the Earth: Two Thousand Years of Map Projections'', John P. Snyder, 1993, pp. 60–62, ISBN 0-226-76747-7〕 The projection is: :$x\; =\; \backslash rho\; \backslash sin\; E\backslash ,$ :$y\; =\; \backslash cot\; \backslash varphi\_1\; -\; \backslash rho\; \backslash cos\; E\backslash ,$ where :$\backslash rho\; =\; \backslash cot\; \backslash varphi\_1\; +\; \backslash varphi\_1\; -\; \backslash varphi\backslash ,$ :$E\; =\; \backslash frac$ and φ is the latitude, λ is the longitude, λ0 is the longitude of the central meridian, and φ1 is the standard parallel of the projection.〔(''Map Projections - A Working Manual'' ), USGS Professional Paper 1395, John P. Snyder, 1987, pp. 138–140〕 Parallels of latitude are concentric circular arcs, and the scale is true along these arcs. On the central meridian and the standard latitude shapes are not distorted. The inverse projection is given by: :$\backslash varphi\; =\; \backslash cot\; \backslash varphi\_1\; +\; \backslash varphi\_1\; -\; \backslash rho\backslash ,$ :$\backslash lambda\; =\; \backslash lambda\_0\; +\; \backslash rho\; \backslash \; /\; \backslash cos\; \backslash varphi$ where :$\backslash rho\; =$± $(x^2\; +\; (\; \backslash cot\; \backslash varphi\_1\; -\; y)^2)^$ taking the sign of $\backslash varphi\_1$. Special cases of the Bonne projection include the sinusoidal projection, when φ1 is zero, and the Werner projection, when φ1 is π/2. The Bonne projection can be seen as an intermediate projection in the unwinding of a Werner projection into a Sinusoidal projection; an alternative intermediate would be a Bottomley projection〔(Between the Sinusoidal projection and the Werner: an alternative to the Bonne ), Henry Bottomley 2002〕 ==See also== *List of map projections 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「Bonne 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.
