The Hammer retroazimuthal projection is a modified azimuthal proposed by Ernst Hermann Heinrich Hammer in 1910. As a retroazimuthal projection, azimuths (directions) are correct from any point to the designated center point.〔 In whole-world presentation, the back and front hemispheres overlap, making the projection a non-injective function. Given a radius ''R'' for the projecting globe, the projection is defined as: : : where : and : The latitude and longitude of the point to be plotted are ''φ'' and ''λ'' respectively, and the center point to which all azimuths are to be correct is given as ''φ''1 and ''λ''0. ==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「Hammer retroazimuthal projection」の詳細全文を読む スポンサード リンク
