Constructor Detail

BoundingBox

public BoundingBox(WGS84Point southWestCorner,
                   WGS84Point northEastCorner)

create a bounding box defined by two coordinates

BoundingBox

public BoundingBox(double southLatitude,
                   double northLatitude,
                   double westLongitude,
                   double eastLongitude)

Create a bounding box with the specified latitudes and longitudes. This constructor takes the order of the points into account.

Parameters:

northLatitude -

southLatitude -

westLongitude -

eastLongitude -

Throws:

IllegalArgumentException - When the defined BoundingBox would go over one of the poles. This kind of box is not supported.

Method Detail

getNorthWestCorner

public WGS84Point getNorthWestCorner()

Returns the NorthWestCorner of this BoundingBox as a new Point.

Returns:

getNorthEastCorner

public WGS84Point getNorthEastCorner()

Returns the NorthEastCorner of this BoundingBox as a new Point.

Returns:

getSouthEastCorner

public WGS84Point getSouthEastCorner()

Returns the SouthEastCorner of this BoundingBox as a new Point.

Returns:

getSouthWestCorner

public WGS84Point getSouthWestCorner()

Returns the SouthWestCorner of this BoundingBox as a new Point.

Returns:

getLatitudeSize

public double getLatitudeSize()

Returns the size of the bounding box in degrees of latitude. The value returned will always be positive.

Returns:

getLongitudeSize

public double getLongitudeSize()

Returns the size of the bounding box in degrees of longitude. The value returned will always be positive.

Returns:

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

contains

public boolean contains(WGS84Point point)

intersects

public boolean intersects(BoundingBox other)

toString

public String toString()

Overrides:

toString in class Object

getCenter

public WGS84Point getCenter()

expandToInclude

public void expandToInclude(BoundingBox other)

Expands this bounding box to include the provided bounding box. The expansion is done in the direction with the minimal distance. If both distances are the same it'll expand in east direction. It will not cross poles, but it will cross the 180-Meridian, if thats the shortest distance.
If a precise specification of the northEast and southWest points is needed, please create a new bounding box where you can specify the points separately.

Parameters:

other -

getEastLongitude

public double getEastLongitude()

getWestLongitude

public double getWestLongitude()

getNorthLatitude

public double getNorthLatitude()

getSouthLatitude

public double getSouthLatitude()

intersects180Meridian

public boolean intersects180Meridian()
