Method Detail

transformNativeHeadingToWgs84

public double transformNativeHeadingToWgs84(double xComp,
                                            double yComp,
                                            double lon,
                                            double lat)

Transforms a heading in native grid co-ordinates (degrees clockwise from positive y-direction) into a heading in WGS84 (degrees clockwise from north).

Specified by:

transformNativeHeadingToWgs84 in class AbstractTransformedGrid

Parameters:

xComp - The x-component of the heading

yComp - The y-component of the heading

lon - The longitude of the given components

lat - The latitude of the given components

Returns:

The transformed heading

getDomainObjects

public Array2D<GridCell2D> getDomainObjects()

Description copied from interface: DiscreteDomain

Returns an Array of domain objects that comprise this domain.

contains

public boolean contains(HorizontalPosition position)

Returns:

true if the given position is contained within this domain.

getBoundingBox

public BoundingBox getBoundingBox()

Description copied from interface: HorizontalDomain

Returns the bounding box of the domain in the domain's own coordinate reference system. For domains which do not have a native co-ordinate reference system this may return a BoundingBox in a different CRS. Consequently this BoundingBox is not guaranteed to be a tight bound around the domain.

getGeographicBoundingBox

public org.opengis.metadata.extent.GeographicBoundingBox getGeographicBoundingBox()

Description copied from interface: HorizontalDomain

Returns the bounding box of the domain in WGS84 latitude-longitude coordinates.

getXSize

public int getXSize()

Returns:

The size of the x-axis

getYSize

public int getYSize()

Returns:

The size of the y-axis

size

public long size()

Description copied from interface: HorizontalGrid

Returns the size of this domain. Equivalent to getXSize() * getYSize()

hashCode

public int hashCode()

Specified by:

hashCode in interface HorizontalGrid

Overrides:

hashCode in class Object

equals

public boolean equals(Object obj)

Specified by:

equals in interface HorizontalGrid

Overrides:

equals in class Object
