Coordinate Systems
A converter is created based on the source and target coordinate systems you specify or
just one coordinate system if you are converting between spherical and projected
coordinates.
// Get the needed coordinate systems.
ICoordSys cs = csService.GetCoordSys(“MENTOR:UTM84-31N”);
// Get the source and target coordinate systems
ICoordSys csSource = cs.GetCoordSys("MENTOR: UTM84-11N");
ICoordSys csTarget = cs.GetCoordSys("MENTOR: UTM84-12N");
// Create a coordinate system converter between two
// coordinate systems.
ICoordSysConverter csConverter = cs.CreateConverter(csSource,
csTarget);
// Create a converter to go from spherical to projected.
ICoordSysConverter sphereToProject;
sphereToProject = cs.CreateConverterFromReference(csSource);
// Create a converter to go from projected to spherical
ICoordSysConverter projectToSphere;
projectToSphere = cs.CreateConverterToReference csSource);
Once you have a converter reference, you can convert Point3 references using any of
the following overloaded Convert methods:
public Point3 Convert(Point3, out ReturnStatus);
public Point3 [] Convert(Point3[], out ReturnStatus);
public void Convert(ref Point3, out ReturnStatus);
public void Convert(ref Point3 [], out ReturnStatus);
You should notice from the method signatures above that all of the Convert methods use
a ReturnStatus output parameter to indicate success or error/warning conditions.
Please see “Return Status” on page 4-220 for more details.
