LAND GLOBE MAPPING PROJECTION METHOD AND MAP PRODUCED ACCORDING TO THE METHOD

摘要

The present invention relates to a method of cartographic projection of at least a portion of the terrestrial globe (1) in which a projection cylinder, containing the globe (1) or secant with it, is defined and the points of the globe are projected, of which the coordinates are defined by a longitude φ) and a latitude (theta), on this cylinder, associating with each longitude (φ) an abscissa (X), at each latitude (theta) an ordinate (Y), in a reference frame of developed cylinder (2), characterized by the fact that a sequence of n + 1 latitude angles (theta0, ..., thetan) is determined, defining n (n = 2) distinct ranges of latitudes , we divide each northern and / or southern hemisphere of the globe (1) into n peripheral zones (4) of latitudes corresponding to the n ranges of the sequence, each defined by two parallel (5, 6) of limit latitude, we project the parallels (5, 6) limit latitude on the projection cylinder and it is projected the point (A) of one of the n regions (4) of latitudes at a point (A ') of the ordinate cylinder that is interpolated between those of the projected limit latitude parallels, as a function of the relative latitude (theta) of the point (A) between the two parallels (5, 6). With the invention we obtain a simple projection method and without excessive calculations.
