Interface EqualArc

All Superinterfaces:

Projection, java.io.Serializable

All Known Implementing Classes:

CADRG, LLXY

public interface EqualArc
extends Projection

A designator interface to let layers know that a Projection is an Equal Arc projection, meaning that the variations in latitude and longitude are constant.

Method Summary

double	getXPixConstant() Returns the x pixel constant of the projection.

Method Detail

getXPixConstant

double getXPixConstant()

Returns the x pixel constant of the projection. This was calculated when the projection was created. Represents the number of pixels around the earth (360 degrees).

getYPixConstant

double getYPixConstant()

Returns the y pixel constant of the projection. This was calculated when the projection was created. Represents the number of pixels from 0 to 90 degrees.
