TMCoord

public TMCoord(Angle latitude,
               Angle longitude,
               double easting,
               double northing,

               double falseEasting,
               double falseNorthing,
               double scale)

Create an arbitrary set of Transverse Mercator coordinates with the given values.

Parameters:

latitude - the latitude Angle.

longitude - the longitude Angle.

easting - the easting distance value in meters.

northing - the northing distance value in meters.

originLatitude - the origin latitude Angle.

centralMeridian - the central meridian longitude Angle.

falseEasting - easting value at the center of the projection in meters.

falseNorthing - northing value at the center of the projection in meters.

scale - scaling factor.

Throws:

java.lang.IllegalArgumentException - if latitude, longitude, originLatitude or centralMeridian is null.

fromLatLon

public static TMCoord fromLatLon(Angle latitude,
                                 Angle longitude,
                                 Globe globe,
                                 java.lang.Double a,
                                 java.lang.Double f,
                                 Angle originLatitude,
                                 Angle centralMeridian,
                                 double falseEasting,
                                 double falseNorthing,
                                 double scale)

Create a set of Transverse Mercator coordinates from a pair of latitude and longitude, for the given Globe and projection parameters.

Parameters:

latitude - the latitude Angle.

longitude - the longitude Angle.

globe - the Globe - can be null (will use WGS84).

a - semi-major ellipsoid radius. If this and argument f are non-null and globe is null, will use the specfied a and f.

f - ellipsoid flattening. If this and argument a are non-null and globe is null, will use the specfied a and f.

originLatitude - the origin latitude Angle.

centralMeridian - the central meridian longitude Angle.

falseEasting - easting value at the center of the projection in meters.

falseNorthing - northing value at the center of the projection in meters.

scale - scaling factor.

Returns:

the corresponding TMCoord.

Throws:

java.lang.IllegalArgumentException - if latitude or longitude is null, or the conversion to TM coordinates fails. If the globe is null conversion will default to using WGS84.

fromTM

public static TMCoord fromTM(double easting,
                             double northing,
                             Globe globe,
                             Angle originLatitude,
                             Angle centralMeridian,
                             double falseEasting,
                             double falseNorthing,
                             double scale)

Create a set of Transverse Mercator coordinates for the given Globe, easting, northing and projection parameters.

Parameters:

easting - the easting distance value in meters.

northing - the northing distance value in meters.

globe - the Globe - can be null (will use WGS84).

originLatitude - the origin latitude Angle.

centralMeridian - the central meridian longitude Angle.

falseEasting - easting value at the center of the projection in meters.

falseNorthing - northing value at the center of the projection in meters.

scale - scaling factor.

Returns:

the corresponding TMCoord.

Throws:

java.lang.IllegalArgumentException - if originLatitude or centralMeridian is null, or the conversion to geodetic coordinates fails. If the globe is null conversion will default to using WGS84.
