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:
lam
- the geographic x ordinate (in radians)phi
- the geographic y ordinatee (in radians)out
- 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)out
- 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
-
isRectilinear
public boolean isRectilinear()Description copied from class:Projection
Tests whether under this projection lines of latitude and longitude form a rectangular grid- Overrides:
isRectilinear
in classCylindricalProjection
-
getEPSGCode
public int getEPSGCode()Returns the ESPG code for this projection, or 0 if unknown.- Overrides:
getEPSGCode
in classProjection
-
toString
- Overrides:
toString
in classCylindricalProjection
