All classes in this API are in the SRM package.
The SRM classes provide the following functionality:
A sample program to convert a Celestiodetic 3D coordinate to a Celestiocentric 3D coordinate is as follows:
import SRM.*; public class CdToCcConv { public static void main (String args[]) { System.out.println( "*** Sample program using SRM Java API to convert a 3D coordinate" ); System.out.println( "*** from a Celestiodetic SRF to a Celestiocentric SRF." ); // Declare reference variables for the CD and CC SRFs SRF_Celestiodetic CdSrf = null; SRF_Celestiodetic CdSrf1 = null; SRF_Celestiocentric CcSrf = null; try { // Create a Celestiodetic SRF with WGS 1984 and Identity transformation CdSrf = new SRF_Celestiodetic(SRM_ORM_Code.ORM_WGS_1984, SRM_HSR_Code.HSR_WGS_1984_IDENTITY); // Create a Celesticentric SRF with WGS 1984 and Identity transformation CcSrf = new SRF_Celestiocentric(SRM_ORM_Code.ORM_WGS_1984, SRM_HSR_Code.HSR_WGS_1984_IDENTITY); // Create a 3D Celestiodetic coordinate with // longitude => 10.0 degrees (note: this input parameter is converted to radians) // latitude => 20.0 degrees (note: this input parameter is converted to radians) // ellipsopidal height => 100.0 meters Coord3D_Celestiodetic CdCoord = (Coord3D_Celestiodetic)CdSrf.createCoordinate3D(Math.toRadians(10.0), Math.toRadians(20.0), 100.0); // Instantiate a 3D Celestiocentric coordinate // This is an alternative method for instantiate a 3D coordinate Coord3D_Celestiocentric CcCoord = new Coord3D_Celestiocentric( CcSrf ); // print out the SRF parameter calues and the coordinate component values System.out.println("CdSrf parameter => \n" + CdSrf); System.out.println("CcSrf parameter => \n" + CcSrf); System.out.println("CdCoord components (source) => \n" + CdCoord); // convert the 3D Celestiodetic coordinate to 3D Celestiocentric coordinate SRM_Coordinate_Valid_Region_Code valRegion = CcSrf.changeCoordinateSRF( CdCoord, CcCoord ); // print out the values of the resulting 3D Celestiocentric coordinate System.out.println("CcCoord components (destination) => \n" + CcCoord + " is " + valRegion ); } catch (SrmException ex) { // catch SrmException and print out the error code and text. System.out.println("Exception caught=> " + ex.what() + ", " + ex); } } }
Running the sample program above will produce the output as follows:
*** Sample program using SRM Java API to convert a 3D coordinate *** from a Celestiodetic SRF to a Celestiocentric SRF.
