Oblq Mercator Oblique Mercator. Oblique Mercator Conformal
projection onto a cylinder. The cylinder is tangent to

its axis lying on a meridian plane. The cylinder is
tangent to the sphere along the equator.
Lambert 1 Para Lambert 1 Parallel. Conformal projection onto a cone,
with its axis coinciding with the z-axis of the ellipsoid.
Lambert 2 Para Lambert 2 Parallel. Conformal projection onto a cone,
with its axis coinciding with the z-axis of the ellipsoid.
The cone is secant to the sphere.
