## Package org.deegree.crs.projections.azimuthal

Azimuthal projections use a plane to project the earth onto.

See:
Description

Class Summary
AzimuthalProjection | The `AzimuthalProjection` class functions as a super class to all azimuthal projections.
LambertAzimuthalEqualArea | The `LambertAzimuthalEqualArea` projection has following properties (From J.S.
StereographicAlternative | `StereographicAlternative` projection may be imagined to be a projection of the earth's surface onto a plane in contact with the earth at a single tangent point from the opposite end of the diameter through that tangent point.
StereographicAzimuthal | The `StereographicAzimuthal` class allows for Stereographic Projections of the Poles, equator as well as oblique.

## Package org.deegree.crs.projections.azimuthal Description

Azimuthal projections use a plane to project the earth onto. A lot of different azimuthal projection exists.

(From wikipedia) Azimuthal projections have the property that directions from a central point are preserved (and hence, great circles through the central point are represented by straight lines on the map). Usually these projections also have radial symmetry in the scales and hence in the distortions: map distances from the central point are computed by a function r(d) of the true distance d, independent of the angle; correspondingly, circles with the central point as center are mapped into circles which have as center the central point on the map.

The mapping of radial lines can be visualized by imagining a plane tangent to the Earth, with the central point as tangent point.
