How to create an ApproximationXform

Summary This example shows how to create an ApproximationXform class. An ApproximationXform object can be used to approximate a geodata transformation that is computationally expensive to improve the transformation speed.

Creating an ApproximationXform

Use the following code example in your application:

[Java]


        static IApproximationXform createApproximateXform(IGeodataXform xform)throws
    Exception{
    //create an approximation of xform
    IApproximationXform approximateXform = new ApproximationXform();
    approximateXform.setGeodataXformByRef(xform);

    //define the approximation parameters
    IGeodataXformApproximation geodataXformApproximation = 
        (IGeodataXformApproximation)approximateXform;
    geodataXformApproximation.setGridSize(32);
    geodataXformApproximation.setApproximation(true);
    geodataXformApproximation.setTolerance(10); //unit is in the input space
    return approximateXform;
}
