C# Class SharpMap.CoordinateSystems.Projections.TransverseMercator

Summary description for MathTransform.

Universal (UTM) and Modified (MTM) Transverses Mercator projections. This is a cylindrical projection, in which the cylinder has been rotated 90°. Instead of being tangent to the equator (or to an other standard latitude), it is tangent to a central meridian. Deformation are more important as we are going futher from the central meridian. The Transverse Mercator projection is appropriate for region wich have a greater extent north-south than east-west.
