veying literature for details on projections.
Customised projection. Certain fixed projec-
tions which cannot be defined by any of the
following options.
Transverse Mercator. Conformal projection
onto a cylinder with its axis lying on the
equatorial plane. The cylinder is tangential to
a meridian.
A customised projection for use in the UK,
based on the UTM projection.
Universal Transverse Mercator. Transverse
Mercator Projection with fixed zone-defining
constants. The central meridian is selected
automatically according to the selected zone
number.
Oblique Mercator. Oblique Mercator Confor-
mal projection onto a cylinder. The cylinder is
tangent to any circle other than the equator
or a meridian.
Mercator. Conformal projection onto a cylin-
der with its axis lying on a meridian plane.
The cylinder is tangent to the sphere along
the equator.
Lambert 1 Parallel. Conformal projection onto
a cone, with its axis coinciding with the z-
axis of the ellipsoid.
Lambert 2 Parallel. Conformal projection onto
a cone, with its axis coinciding with the z-
