Distortion values are symmetric across the equator and the central meridian. Deformations are enormous at the left and right map edges.
Area, distance, and scale distortions rapidly grow with distance from the central meridian or the two standard lines as specified above. If it is less than 1.0, there are two approximately straight lines with accurate scale equidistant from and on each side of the central meridian. Distances are accurate along the central meridian if the scale factor is 1.0. It generally does not maintain true directions, but angles and shapes are maintained at infinitesimal scale. Transverse Mercator is a conformal map projection. Two points on the equator, exactly 90° away from the central meridian, project to The otherĮach being in the center of its hemisphere. Similarly, all three lines extend to infinity on both ends whenĪpproaching meridians 90° away from the central meridian. Is projected as two straight lines at the top and bottom of the map. Line in the middle of the map, splitting the projected area into Within 90° of the central meridian projects as horizontal straight Line though the South Pole, also extending to infinity. Southern parts of those meridians are projected as a horizontal Pole, extending to infinity when approaching the equator. Meridian project as a horizontal straight line through the North Northern parts of meridians 90° away from the central Lines are presented as one vertical line in the middle of the Transverse Mercator is a transverse cylindric projection. The subsections below describe the transverse Mercator projection properties. The transverse Mercator projection is shown centered on Greenwich. The Gauss-Krüger name refers to the ellipsoidal form reevaluated by Louis Krüger in 1912. First formulas with ellipsoidal correction were developed by Carl F. The spherical version of the projection was presented by Johann H. Various countries use this projection for their topographic maps and large-scale coordinate systems. The Universal Transverse Mercator (UTM) coordinate system and Gauss-Krüger coordinate systems are based on the transverse Mercator projection and the State Plane Coordinate System uses it for all north-south zones. This projection is best suited for north-south oriented areas. This centering minimizes distortion of all properties in that region. The central meridian is placed in the center of the region of interest. The result is a conformal projection that does not maintain true directions. The transverse Mercator projection, also known as the Gauss-Krüger projection, is similar to Mercator except that the cylinder touches the sphere or ellipsoid along a meridian instead of the equator.
