The first to do so was Gerardo Mercator, who made the famous … The light coming from a source at the middle radiates outward in all directions, but is blocked out by the points A and B on the surface. On a pseudocylindrical map, points further from the equator have higher latitudes than other points, preserving the north-south relationship. It is neither conformal nor equal-area but instead offers a compromise presentation. Homolosine projection definition, an equal-area projection of the world, distorting ocean areas in order to minimize the distortion of the continents. 3 Answers. Mollweide projection definition is - an equal-area map projection capable of showing the entire surface of the earth in the form of an ellipse with all parallels as straight lines more widely spaced at the equator than at the poles, with the central meridian as one half the length of the equator, and with all other meridians ellipses equally spaced. Every projection has its own set of advantages and disadvantages. It is an equal-area projection designed for small-scale maps. Areas are represented accurately. It is from there that develops the study of geography and maps, whose evolution flourished during the Renaissance. The three windings of the coils are connected together at points, a 1, b 1 and c 1 to produce a common neutral connection for the three individual phases. The projections stretch from east to west according to their geometric constructions and are the same at any chosen latitude. This projection compresses shapes in higher latitudes, but shapes are good in the central section. All parallels are straight lines, and all meridians are equally spaced elliptical arcs.
