public interface Site

An interface describing a geographical location on the Earth. This interface is used mainly in astronomical context. It describes methods to set and retrieve the longitude, latitude and the elevation of a site.

Field Summary

static double[]	ALTITUDES The altitudes of the known observatories in meters.
static double[]	LATITUDES The latitudes of the known observatories in degrees.
static double[]	LONGITUDES The longitudes of the known observatories in degrees, west is negativ.
static String[]	OBSERVATORIES Known observatories, names.

Method Summary

double	getElevation() Gets the elevation above sea level of this site in meters.
double	getLatitude() Returns the latitude of this site.
double	getLongitude() Returns the longitude of this site.
void	setElevation(double height) Sets the elevation above sea level of this site in meters.
void	setLatitude(double phi) Sets the latitude of this site, in radians.
void	setLongitude(double lambda) Sets the longitude of this site, in radians.

Field Detail

Method Detail

getLongitude

double getLongitude()

Returns the longitude of this site. It is negative for western longitudes. The returned value is always in radians.

Returns:

The longitude in radians.

setLongitude

void setLongitude(double lambda)

Sets the longitude of this site, in radians. It is negative for eastern longitudes.

getLatitude

double getLatitude()

Returns the latitude of this site. It is negative for southern latitudes. The returned value is always in radians.

Returns:

The latitude in radians.

setLatitude

void setLatitude(double phi)

Sets the latitude of this site, in radians. It is negative for southern latitudes.

getElevation

double getElevation()

Gets the elevation above sea level of this site in meters.

setElevation

void setElevation(double height)

Sets the elevation above sea level of this site in meters.
