Miller cylindrical projection – Expand Your Mind

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 ⁄, projected according to Mercator, and then the result is multiplied by ⁄ to retain scale along the equator. Hence: where λ is the longitude from the central meridian of the projection, and φ is the latitude. Meridians are thus about 0.733 the length of the equator. - 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. where λ is the longitude from the central meridian of the projection, and φ is the latitude. Meridians are thus about 0.733 the length of the equator. The Osborn Maitland Miller Cartographic Medal was established in 1968 by the American Geographical Society Council. The Osborn Maitland Miller Cartographic Medal honors 'outstanding contributions in the field of cartography or geodesy'. History Miller's forty-six year career with the Americ... Commonly, a map projection is a systematic transformation of the latitudes and longitudes of locations on the surface of a sphere or an ellipsoid into locations on a plane. Map projections are necessary for creating maps. All map projections distort the surface in some fashion. Depending on the purpose of the map, so... An azimuth ( ) (from Arabic al-sumūt, meaning 'the directions') is an angular measurement in a spherical coordinate system . The vector from an observer ( origin ) to a point of interest is projected perpendicularly onto a reference plane , the angle between the projected vector and a reference vector on the reference plane is... 'Bearing' is a term used in navigation to refer, depending on the context, to either (A) the direction of motion, or, (B) the direction of a distant object relative to the current course (or the 'change' in course that would be needed to get to that distant object), or (C), the degrees away from North of a distant point relative to the current... The equirectangular projection (also called the equidistant cylindrical projection, geographic projection, or la carte parallélogrammatique projection, and which includes the special case of the plate carrée projection or geographic projection) is a simple map projection attributed to Marinus of Tyre, who Ptolemy claims i...
