public interface ILcdAzimuthal
extends ILcdProjection

ILcdAzimuthals are ILcdProjection objects that have a central point of zero distortion. This central point is the origin of the ILcdAzimuthal. The azimuth (direction) from the origin point to any other point on the map is shown correctly.

An ILcdAzimuthal has an origin which is expressed in lat-lon coordinates.

Tangent plane projections are examples of ILcdAzimuthal.

Method Details

setOriginLat

void setOriginLat(double aLatitude)

Sets the latitude of the origin to aLatitude. Changing the origin of an azimuthal projection changes also its aspect. The normal aspect of an azimuthal projection corresponds to the origin at one of the poles. The transverse aspect corresponds to the origin on the equator. The oblique aspect corresponds to any other origin.

Parameters:

aLatitude - The new originLat value.

See Also:

• getOriginLat()

getOriginLat

double getOriginLat()

Gets the latitude of the origin.

Returns:

the latitude of the origin.

See Also:

• setOriginLat(double)

setOriginLon

void setOriginLon(double aLongitude)

Sets the longitude of the origin to aLongitude.

Parameters:

aLongitude - The new originLon value.

See Also:

• getOriginLon()

getOriginLon

double getOriginLon()

Gets the longitude of the origin.

Returns:

the longitude of the origin.
