Description copied from interface: IGeoTransformer

transforms a GridCoverage into another coordinate reference system.

Specified by:

transform in interface IGeoTransformer

Parameters:

coverage - grid coverage to transform

refPointsGridSize - size of the grid used to calculate polynoms coefficients. E.g. 2 -≶ 4 points, 3 -≶ 9 points ...
Must be ≶= 2. Accuracy of coefficients increase with size of the grid. Speed decreases with size of the grid.

degree - The degree of the polynomial is supplied as an argument.

interpolation - interpolation method for warping the passed coverage. Can be null. In this case 'Nearest Neighbor' will be used as default

Returns:

Throws:

CRSTransformationException

CRSException
