Method Detail

toPointArray

public Geo[] toPointArray()

Convert the GeoArray to an array of Geos.

Specified by:

toPointArray in interface GeoArray

Returns:

Geo[]

toLLDegrees

public double[] toLLDegrees()

Convert the GeoArray to an array of decimal degree values, alternating lat, lon, lat, lon.

Specified by:

toLLDegrees in interface GeoArray

Returns:

lat/lon double[] of decimal degrees

toLLRadians

public double[] toLLRadians()

Convert the GeoArray to an array of radian values, alternating lat, lon, lat, lon.

Specified by:

toLLRadians in interface GeoArray

Returns:

lat/lon double[] of radians

area

public double area()

Computes the area of a polygon on the surface of a unit sphere. For a non unit sphere, multiply this by the radius of sphere squared. The value might be negative based on the counter-clockwise order of the coordinates, but the absolute value is valid. This method will test for closed polygon coordinates and handle that situation.

Specified by:

area in interface GeoArray

Returns:

area value.
