Vector2D	applyTo(GeodeticPoint geodeticPoint) Returns Easting value and Northing value in meters from geodetic coordinates.
boolean	canMap(GeodeticPoint geodeticPoint) Returns a boolean depending if the geodetic point can be map with the selected projection method.
EnumLineProperty	getLineProperty() Getter for line property .
double	getMaximumEastingValue() Getter for the maximum value for X projected.
double	getMaximumLatitude() Getter for the maximum latitude that the projection can map.
BodyShape	getReference() Get the system of reference used.

Method Detail

canMap

boolean canMap(GeodeticPoint geodeticPoint)

Returns a boolean depending if the geodetic point can be map with the selected projection method.

Parameters:

geodeticPoint - geodetic point to test if representable.

Returns:

True if the geodetic point can be represented on the map with the chosen projection method.

applyTo

Vector2D applyTo(GeodeticPoint geodeticPoint)
                 throws OrekitException

Returns Easting value and Northing value in meters from geodetic coordinates.

Parameters:

geodeticPoint - the geodetic point to transform.

Returns:

Vector2D containing Easting value and Northing value in meters.

Throws:

OrekitException - thrown if projection could not be computed

applyTo

Vector2D applyTo(double lat,
                 double lon)
                 throws OrekitException

Returns Easting value and Northing value in meters from latitude and longitude coordinates.

Parameters:

lat - latitude of the point to project.

lon - longitude of the point to project.

Returns:

Vector2D containing Easting value and Northing value in meters.

Throws:

OrekitException - thrown if projection could not be computed

applyInverseTo

GeodeticPoint applyInverseTo(double x,
                             double y)
                             throws OrekitException

Inverse projection. Returns geodetic coordinates.

Parameters:

x - abscissa coordinate

y - ordinate coordinate

Returns:

geodetic coordinates.

Throws:

OrekitException - thrown if inverse projection could not be computed

applyInverseTo

GeodeticPoint applyInverseTo(double x,
                             double y,
                             double alt)
                             throws OrekitException

This is the Two standard parallel Mercator Projection model. The latitude and the longitude of the given point to convert can be defined from any natural origin and the user can set the altitude.
