init

project
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:
lplam
- the geographic x ordinate (in radians)lpphi
- the geographic y ordinatee (in radians)xy
- the projected coordinate (in coordinate system units)- Returns:
- the target coordinate
-
projectInverse
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
-
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
- Overrides:
toString
in classPseudoCylindricalProjection
-
equals
Description copied from class:Projection
Represents quality between possible outputs ofProjection.project(ProjCoordinate, ProjCoordinate)
. Subclasses of Projection should capture additional state that is used in the project method and delgate to base. Note: The name of the projection is not part of equality.- Overrides:
equals
in classProjection
-
hashCode
public int hashCode()Description copied from class:Projection
Hash of those fields considered in Projection equalituy. Subclasses that override equality should override hashCode.- Overrides:
hashCode
in classProjection
