<H2>Description</H2>
This class encapsulates an Earth-Centered-Earth-Fixed coordinate.
This is also known as a cartesian coordinate. It is made up of three
distances all originating at the center of the Earth.
<H2>Constructors</H2>
<DL COMPACT>
<DT><PRE><B>CEarthCoordinate</B>()
<B>CEarthCoordinate</B>( const CEarthCoordinate& source )</PRE><DD>
Constructs an empty coordinate or copies another <B>CEarthCoordinate</B>.
</DL>
<H2>Methods</H2>
<DL COMPACT>
<DT><PRE>void <B>Copy</B>( const CEarthCoordinate& coordinate )</PRE><DD>
Copies the contents of another <B>CEarthCoordinate</B>.
<DT><PRE>void <B>Get</B>( double& x_coordinate, double& y_coordinate, double& z_coordinate )</PRE><DD>
This allows you to retrieve all the data members in one function call.
<DT><PRE>double <B>GetXCoordinateInMeters</B>( void ) const</PRE><DD>
This method returns the X axis coordinate in meters.
Positive values point towards the intersection of the Prime Meridian and the Equator.
<DT><PRE>double <B>GetYCoordinateInMeters</B>( void ) const</PRE><DD>
This method returns the Y axis coordinate in meters.
Positive values point towards the intersection of 90 degrees east of Prime Meridian and the Equator.
<DT><PRE>double <B>GetZCoordinateInMeters</B>( void ) const</PRE><DD>
This method returns the Z axis coordinate in meters.
Positive values point towards the North Pole, negative values towards the South Pole.
<DT><PRE>void <B>Set</B>( double x_coordinate, double y_coordinate, double z_coordinate )</PRE><DD>
This lets you set all of the data members in a single function call.
<DT><PRE>void <B>SetXCoordinateInMeters</B>( double x_coordinate )</PRE><DD>
This method sets the X axis coordinate in meters.
<DT><PRE>void <B>SetYCoordinateInMeters</B>( double y_coordinate )</PRE><DD>
This method sets the Y axis coordinate in meters.
<DT><PRE>void <B>SetZCoordinateInMeters</B>( double z_coordinate )</PRE><DD>
This method sets the Z axis coordinate in meters.

<H2>Operators</H2>
<DL COMPACT>
<DT><PRE><B>=</B> ( const CEarthCoordinate& source )</PRE><DD>
Basically calls <B>Copy</B>().

<H2>Example</H2>
<PRE><CODE>#include <stdio.h>
#include <GFC.h>
#pragma hdrstop
void main( void )
{
CPolarCoordinate here;
<B>CEarthCoordinate</B> there;
// here is 39 degrees 12.152 minutes North Latitude, 76 degrees 46.795 minutes West Longitude
here.SetUpDownAngleInDegrees( CMath::ConvertDegreesMinutesSecondsCoordinateToDecimalDegrees( 39.0, 12.152, 0.0 ) );
here.SetLeftRightAngleInDegrees( CMath::ConvertDegreesMinutesSecondsCoordinateToDecimalDegrees( -76.0, 46.795, 0.0 ) );
here.SetDistanceFromSurfaceInMeters( 1000.0 );
CEarth earth;
earth.Convert( here, there );
}</CODE></PRE>
