Classifications
cylindric

Aspect
One possible transverse development for ellipsoidal transverse Mercator.
Graticule
Meridians: Central meridian is straight; others are complex curves.
Parallels: Complex curves.
Scale
Highly inflated at the extremities away from the central meridian.
Distortion
Low near the central meridian, increasing away from it.
Similar projections
The ellipsoidal transverse Mercator has parallels correctly (but not evenly) spaced along the central meridian.
Wallis 2 transverse Mercator is similar until reaching the extremities.
Origin
Described by E.H. Thompson in 1945, as communicated to L.P. Lee, who published comments in 1976. This projection arises as an intermediate transformation on the way to the ellipsoidal transverse Mercator.
