Class ResidualGrid.Data

java.lang.Object
org.apache.sis.io.wkt.FormattableObject
org.apache.sis.referencing.operation.builder.ResidualGrid.Data
All Implemented Interfaces:
Function<int[],Number>, org.opengis.referencing.operation.Matrix
Enclosing class:
ResidualGrid
private final class ResidualGrid.Data extends FormattableObject implements org.opengis.referencing.operation.Matrix, Function<int[],Number>
View over one target dimension of the localization grid. Used for populating the ParameterDescriptorGroup that describes the MathTransform. Those parameters are themselves used for formatting Well Known Text. Current implementation can be used only when the number of grid dimensions is 2. If a grid has more dimensions, then tensors would need to be used instead of matrices.

This implementation cannot be moved to the DatumShiftGrid parent class because this class assumes that the translation vectors are added to the source coordinates. This is not always true; for example France Geocentric interpolations add the translation to coordinates converted to geocentric coordinates.
