Method Detail
-
initialize
public void initialize()
Description copied from class:Projection
Initialize the projection. This should be called after setting parameters and before using the projection. This is for performance reasons as initialization may be expensive.- Overrides:
initialize
in classProjection
-
getHeightOfOrbit
public double getHeightOfOrbit()
Description copied from class:Projection
Get height of orbit - Geostationary satellite projection- Overrides:
getHeightOfOrbit
in classProjection
- Returns:
- Height of orbit
-
setHeightOfOrbit
public void setHeightOfOrbit(double h)
Description copied from class:Projection
Set height of orbit - Geostationary satellite projection- Overrides:
setHeightOfOrbit
in classProjection
- Parameters:
h
- Height of orbit
-
project
public ProjCoordinate project(double lplam, double lpphi, ProjCoordinate out)
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)out
- the projected coordinate (in coordinate system units)- Returns:
- the target coordinate
-
project_s
public void project_s(double lplam, double lpphi, ProjCoordinate out)
-
project_e
public void project_e(double lplam, double lpphi, ProjCoordinate out)
-
projectInverse
public ProjCoordinate projectInverse(double xyx, double xyy, ProjCoordinate out)
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:
xyx
- the projected x ordinate (in coordinate system units)xyy
- the projected y ordinate (in coordinate system units)out
- the inverse-projected geographic coordinate (in radians)- Returns:
- the target coordinate
-
projectInverse_s
public void projectInverse_s(double xyx, double xyy, ProjCoordinate out)
-
projectInverse_e
public void projectInverse_e(double xyx, double xyy, ProjCoordinate out)
-
isEqualArea
public boolean isEqualArea()
Returns true if this projection is equal area- Overrides:
isEqualArea
in classProjection
- Returns:
- true if this projection is equal-area
-
hasInverse
public boolean hasInverse()
Description copied from class:Projection
Tests whether this projection has an inverse. If this method returnstrue
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
-
toString
public java.lang.String toString()
- Overrides:
toString
in classProjection
-
equals
public boolean equals(java.lang.Object that)
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
