Using the same 2:1 elliptical outer shape as the Mollweide projection, Hammer intended to reduce distortion toward the outer limbs, where it is extreme in the Mollweide. ==Development== Directly inspired by the Aitoff projection, Hammer suggested the use of the equatorial form of the Lambert azimuthal equal-area projection instead of Aitoff's use of the azimuthal equidistant projection: :$x\; =\; \backslash mathrm\_x\backslash left(\backslash frac\backslash lambda\; 2,\; \backslash phi\backslash right)$ :$y\; =\; \backslash frac\; 1\; 2\backslash mathrm\_y\backslash left(\backslash frac\backslash lambda\; 2,\; \backslash phi\backslash right)$ where $\backslash mathrm\_x$ and $\backslash mathrm\_y$ are the x and y components of the equatorial Lambert azimuthal equal-area projection. Written out explicitly: :$x\; =\; \backslash frac$ The longitude and latitudes can then be calculated by :$$ \begin \lambda &= 2 \arctan \left(longitude from the central meridian and $\backslash phi$ is the latitude.〔''Flattening the Earth: Two Thousand Years of Map Projections'', John P. Snyder, 1993, pp. 130–133, ISBN 0-226-76747-7.〕〔Weisstein, Eric W. ("Hammer–Aitoff Equal-Area Projection." From MathWorld—A Wolfram Web Resource )〕 Visually, the Aitoff and Hammer projections are very similar. The Hammer has seen more use because of its equal-area property. The Mollweide projection is another equal-area projection of similar aspect, though with straight parallels of latitude, unlike the Hammer's curved parallels. 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「Hammer 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.
