Coordinate

public Coordinate()

Coordinate

public Coordinate(double pLat,
                  double pLong)

Construct a location specfied by two angles. Your choice if in degrees or rads, but keep track!

Parameters:

pLong - Longitude or RA

pLat - Latitude or DE

Method Detail

renderAsXML

public void renderAsXML(Writer writer)
                 throws IOException

Throws:

IOException

getPoint3D
