ConcatenatedTransform – Global Mapper

Inherits from

GEOCALCPBW_NAMESPACE::Serializable

Description

This class represents a transformation from a set of Source coordinate reference systems to a set of Target coordinate reference systems that may include both horizontal and vertical data, and which may require multiple component transformation to complete. For example, a ParametricTransform and a VerticalTransform, or a pair of DatumTransforms that use an intermediate, where no direct transform is available.

This class is not intended to actually perform the point data computations. For that, you must generate a PointTransformer, which will be optimized to run data through a pipeline of required transforms, in the appropriate order, with the necessary unit conversions, projections, etc.

Public Methods

Method	Description
GeneratePointTransformer	Creates a PointTransformer object to handle the actual point transformations of this ConcatenatedTransform.
IsTransformNeeded	Returns True if a CoordTransform is required to convert between the sources and targets, False otherwise.
GetDimensions	Returns the dimensions of this ConcatenatedTransform.
SetPassThrough	Sets this Transform to apply no Transformations, even if one is required.
get_Initialized	Returns the initialized boolean which represents whether the transformation has been fully set up or not.
set_Initialized	Sets a boolean value that represents whether the transformation has been fully initialized.
get_Sources	Returns the collection of all Source CoordSys objects.
GetSourceHorizontalCoordSys	Returns the single HorizontalCoordSys from the collection of all sources, if one exists.
GetSourceVerticalCoordSys	Returns the single VerticalCoordSys from the collection of all sources, if one exists.
get_Targets	Returns the collection of all Target CoordSys objects.
GetTargetHorizontalCoordSys	Returns the single HorizontalCoordSys from the collection of all targets, if one exists.
GetTargetVerticalCoordSys	Returns the single VerticalCoordSys from the collection of all targets, if one exists.
get_Transforms	Returns the collection of all single CoordTransforms that compose the ConcatenatedTransform.
get_AreaOfUse	Returns the AreaOfUse where the ConcatenatedTransform is valid.
get_Usages	Returns the Usage where the ConcatenatedTransform is valid.
get_Accuracy	Returns the accuracy of the ConcatenatedTransform, if one has been specified.
set_Accuracy	Sets the accuracy of the ConcatenatedTransform.
get_SourceEpoch	Gets the Source Epoch, if one has been specified.
set_SourceEpoch	Sets the Source Epoch.
get_TargetEpoch	Gets the Target Epoch, if one has been specified. This is relevant only for HTDP and Time-Dependent Helmert transformations.
set_TargetEpoch	Sets the Target Epoch. This is relevant only for HTDP and Time-Dependent Helmert transformations.
GetDescription	Returns a string that identifies the Coordinate systems used in the ConcatenatedTransform.
GetTransformDescription	Returns a string that details the CoordinateTransform process used in the ConcatenatedTransform.
