ImplementsIProjection

Transverse Mercator projection -- The most used projection family in the world: UTM, US State Plane, Gauss Kruger, etc. State Plane Coordinate System, used for predominantly north-south state zones. Most new USGS maps after 1957 use this projection. Cylindrical, conformal (scale is the same in different directions at a point in a local region).
