The Geostationary Satellite Projection

Adapted from https://github.com/OSGeo/proj.4/blob/4.9/src/PJ_geos.c

NOTE: Not all valid coordinates in this projection will transform to valid terrestrial coordinates, this is especially true of "Full Disk" earth coverages. If one must deal with coverages in this projection with generalized code which requires the coverage bounding-box coordinates to transform to valid terrestrial values consider clipping to a rectangle inscribing the ellipsoid.

Method Details

getParameterDescriptors

public ParameterDescriptorGroup getParameterDescriptors()

Description copied from class: MapProjection

Returns the parameter descriptors for this map projection. This is used for a providing a default implementation of MapProjection.getParameterValues(), as well as arguments checking.

Specified by:

getParameterDescriptors in class MapProjection

Returns:

The parameter descriptors for this math transform, or null.

• OperationMethod.getParameters()

getParameterValues

public ParameterValueGroup getParameterValues()

Description copied from class: MapProjection

Returns the parameter values for this map projection.

Overrides:

getParameterValues in class MapProjection

Returns:

A copy of the parameter values for this map projection.

See Also:

• Operation.getParameterValues()

equals

public boolean equals(Object object)

Description copied from class: MapProjection

Compares the specified object with this map projection for equality.

Overrides:

equals in class MapProjection

Parameters:

object - The object to compare with this transform.

Returns:

true if the given object is a transform of the same class and if, given identical source position, the transformed position would be the equals.

hashCode

public int hashCode()

Description copied from class: MapProjection

Returns a hash value for this map projection.

Overrides:

hashCode in class MapProjection
