Coordinate Systems
The following code sample shows Convert method examples using the converters
created above.
// Convert point from source to target coordinate system
Point3 targetPoint = csConverter.Convert( sourcePoint, returnStatus );
Point3 [] targetPoints = csConverter.Convert( sourcePoints,
returnStatus );
// Convert point from spherical to projected.
Point3 projectedPt = sphereToProjected.Convert( sphericalPt,
returnStatus );
Point3 [] projectedPts = sphereToProjected.Convert( sphericalPts,
returnStatus );
// convert point from projected to spherical.
Point3 sphericalPt = projectedToSphere.Convert( projectedPt,
returnStatus );
Point3 [] sphericalPts = projectedToSphere.Convert( projectedPts,
returnStatus );
Coordinate System Interface
The Coordinate Systems interface, ICoordSys, provides properties of the coordinate
system to the application developer. These include the coordinate systems name,
description, surface and vertical units, and the engine specific unit domain. The unit
domain is usually Spherical or Cartesian.
The properties from the ICoordSys interface may be used to save the coordinate system
information. This can be done by storing the values of the properties in an XML file, for
example, for later retrieval and use. The ICoordSys interface provides access to the
properties in a read only fashion. ICoordSys is defined as:
public interface ICoordSys
{
string Description { get; }
string Name { get; }
IUnit NativeSurfaceUnit { get; }
IUnit NativeVerticalUnit { get; }
string UnitDomain { get; }
}
