Aspect
One possible transverse development for the ellipsoidal transverse Mercator.
Graticule
Meridians: Central meridian is straight; others are complex curves.
Parallels: Complex curves, evenly spaced along the central meridian.
Scale
Infinite at the top/bottom extremities. The full map cannot be shown.
Distortion
Low near the central meridian, increasing away from it.
Similar projections
The ellipsoidal transverse Mercator is finite and has parallels correctly (but not evenly) spaced along the central meridian.
Wallis 2 transverse Mercator is finite and similar until reaching the extremities.
Origin
R. König and K.H. Weise discuss and illustrate the projection in 1951. The projection arises as a step in one method of producing the ellipsoidal transverse Mercator. It is also a step in a method devised by Dr. David E. Wallace in the 1980s.
