Wallis 2 transverse Mercator

Classifications

cylindric
conformal

Aspect

One possible transverse development for the ellipsoidal transverse Mercator.

Graticule

Meridians: Central meridian is straight; others are complex curves.
Parallels: Complex curves.

Scale

High at the top/bottom extremities.

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 1 transverse Mercator is infinite and similar until reaching the extremities.
The Thompson transverse Mercator has concave extremities instead of convex.

Origin

This projection arises as a step in a method for obtaining the ellipsoidal transverse Mercator as devised by Dr. David E. Wallace in the 1980s.
