The Miller cylindrical projection is a modified Mercator projection, proposed by Osborn Maitland Miller (1897–1979) in 1942. The latitude is scaled by a factor of 4/5, projected according to Mercator, and then the result is multiplied by 5/4 to retain scale along the equator.〔''Flattening the Earth: Two Thousand Years of Map Projections'', John P. Snyder, 1993, pp. 179, 183, ISBN 0-226-76747-7.〕 Hence: : : or inversely, : : where ''λ'' is the longitude from the central meridian of the projection, and '''' is the latitude.〔(【引用サイトリンク】publisher=Wolfram MathWorld )〕 Meridians are thus about 0.733 the length of the equator. In GIS applications, this projection is known as: "EPSG:54003 - World Miller Cylindrical" ==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「Miller cylindrical projection」の詳細全文を読む スポンサード リンク
