public class CoordSysTransMethod
extends Enum

Defines the projection transformation method type constant.

In projection transformation, if the geographic coordinate system or the source projection and the target projection are different, it is needed to convert the coordinate system.

There are two methods commonly used, they are the equation-based methods and the grid-based methods. This class provides method based on the equation. According to the number of the parameters used in the equation, the equation-based methods can be divided in to three-parameter and seven-parameter methods.For more information about these parameters refer to.
