Class CoordSysTransParameter

  • java.lang.Object
    • com.supermap.data.CoordSysTransParameter

  • public class CoordSysTransParameter
extends java.lang.Object

    The CoordSysTransParameter class.

    Include panning, rotation and scale factor.

    The seven parameters for datum transformation, such as translation, rotate and zoom factors. If the source and target datums are different in projection transformation, it may be necessary to transform from one to another. Generally three-parameter and seven-parameter methods are commonly used to implement datum transformation.
