Related Terms

CONIC CHART

A chart on a conic projection

CONIC CHART WITH TWO STANDARD PARALLELS

A chart on the conic projection with two standard parallels. Also called SECANT CONIC CHART.

CYLINDRICAL CHART

CONIC MAP PROJECTION

A map projection in which the surface of a sphere or spheroid, such as the earth, is conceived as projected onto a tangent or secant cone which is then developed into a plane. In a simple conic map projection the cone is tangent to the sphere or spheroid, in a conic map projection with two standard parallels the cone intersects the sphere or spheroid along two chosen parallels, and in a polyconic map projection a series of cones are tangent to the sphere or spheroid

GNOMONIC CHART

A chart constructed on the gnomonic projection and often used as an adjunct for transferring a great circle to a Mercator chart. Commonly called GREAT CIRCLE CHART

POLYCONIC MAP PROJECTION

A conic map projection in which the surface of a sphere or spheroid, such as the earth, is conceived as developed on a series of tangent cones, which are then spread out to form a plane. A separate cone is used for each small zone. This projection is widely used for maps but seldom used for charts, except for survey purposes. It is not conformal.

CONIC MAP PROJECTION WITH TWO STANDARD PARALLELS

A conic map projection in which the surface of a sphere or spheroid is conceived as developed on a cone which intersects the sphere or spheroid along two standard parallels, the cone being spread out to form a plane. The Lambert conformal map projection is an example. Also called SECANT CONIC MAP PROJECTION.

LAMBERT CONFORMAL CHART

A chart on the Lambert conformal projection

EQUATORIAL CHART

  1. A chart of equatorial areas. 2. A chart on an equatorial map projection

SIMPLE CONIC MAP PROJECTION

A conic map projection in which the surface of a sphere or spheroid, such as the earth, is conceived as developed on a tangent cone, which is then spread out to form a plane.
