Document Summary
Next, three of the most important graphic products are defined. According to different scales, which are the reduction ratio of the ellipsoid on the flat surface. By their nature, they are the product of geodetic surveys. They are intended to represent the elements of the terrain necessary for the reference (x,y,z). In them also the reduction of the ellipsoid on a flat surface is realized. A coordinate system is defined on the ellipsoid to establish the position of a point on the earth"s surface. The situation of a point on the terrestrial ellipsoid is determined by the intersection of a meridian and a parallel, constituting its geographic coordinates longitude and latitude. Meridians: elliptical sections produced by the intersection of the ellipsoid by any plane that contains the axis of revolution of the earth. Parallels: circular sections produced by the intersection of the ellipsoid with planes perpendicular to the axis of revolution.
