Class HorizontalVerticalTransformationStep

Represents a step in the process of transforming between horizontal and/or vertical datums.

HorizontalVerticalTransformationStep

public sealed class HorizontalVerticalTransformationStep : IEquatable<HorizontalVerticalTransformationStep>

Each HorizontalVerticalTransformationStep can be constructed from a well-known ID (WKID) that represents a horizontal (geographic) or a vertical transformation. This API supports thousands of predefined transformations, and all the supported WKIDs are documented in the ArcGIS Pro 3.1 and ArcGIS Enterprise 11.1 Geographic and Vertical Transformation Tables .pdf document.

One or more HorizontalVerticalTransformationStep objects are combined into a HorizontalVerticalTransformation object, and can then be used to control how coordinates are transformed in a Project(Geometry, SpatialReference, DatumTransformation) method call.

Name	Description
HorizontalVerticalTransformationStep(Int32)	Initializes a new instance of the HorizontalVerticalTransformationStep class from a well-known ID.
HorizontalVerticalTransformationStep(String)	Initializes a new instance of the HorizontalVerticalTransformationStep class from a well-known text string.

Name	Description
IsInverse	Gets a value indicating whether this transformation step is an inverted transformation.
IsMissingProjectionEngineFiles	Gets a value indicating whether any files needed by the Projection Engine for this geographic transformation step are missing from the local file system.
ProjectionEngineFilenames	Gets a read-only list of Projection Engine files required to support this geographic transformation step.
Wkid	Gets the well-known ID or 0 if the transformation in this step does not have a well-known ID.
WkText	Gets the well-known text of this transformation step instance.

Name	Description
Equals(HorizontalVerticalTransformationStep)	Returns `true` if the two transformation steps are equal, `false` otherwise.
Equals(Object)	Returns a value indicating if the two objects are equal.
GetHashCode()	Serves as the hash function for the class.
GetInverse()	Returns the inverse of the transformation step or `null` if the transformation is not invertible.
