Method Detail

project
public ProjCoordinate project(double lam, double phi, ProjCoordinate xy)
Description copied from class:Projection
Computes the projection of a given point (i.e. from geographics to projection space). This should be overridden for all projections.- Overrides:
project
in classProjection
- Parameters:
lam
- the geographic x ordinate (in radians)phi
- the geographic y ordinatee (in radians)xy
- the projected coordinate (in coordinate system units)- Returns:
- the target coordinate
-
projectInverse
public ProjCoordinate projectInverse(double x, double y, ProjCoordinate lp)
Description copied from class:Projection
Computes the inverse projection of a given point (i.e. from projection space to geographics). This should be overridden for all projections.- Overrides:
projectInverse
in classProjection
- Parameters:
x
- the projected x ordinate (in coordinate system units)y
- the projected y ordinate (in coordinate system units)lp
- the inverse-projected geographic coordinate (in radians)- Returns:
- the target coordinate
-
getWidth
public double getWidth(double y)
-
hasInverse
public boolean hasInverse()
Description copied from class:Projection
Tests whether this projection has an inverse. If this method returns true then theProjection.inverseProject(ProjCoordinate, ProjCoordinate)
andProjection.inverseProjectRadians(ProjCoordinate, ProjCoordinate)
methods will return meaningful results.- Overrides:
hasInverse
in classProjection
- Returns:
- true if this projection has an inverse
-
isEqualArea
public boolean isEqualArea()
Description copied from class:Projection
Tests whether this projection is equal-area An equal-area projection preserves relative sizes of projected areas.- Overrides:
isEqualArea
in classProjection
- Returns:
- true if this projection is equal-area
-
toString
public java.lang.String toString()
- Overrides:
toString
in classPseudoCylindricalProjection
