Namespace: GameEngine.Geometry
Class: GameEngine/Geometry/ArcGISHorizontalVerticalTransformationStep
Since: 1.0.0
Summary
Represents a step in the process of transforming between horizontal and/or vertical datums.
Constructors
ArcGISHorizontalVerticalTransformationStep(int)
Creates a new ArcGISHorizontalVerticalTransformationStep instance from a well-known ID.
Since 1.0.0
Arguments
| Name | Type | Summary |
|---|---|---|
WKID | int | The well-known ID of the transformation step to create. |
ArcGISHorizontalVerticalTransformationStep(string)
Creates a new ArcGISHorizontalVerticalTransformationStep instance from a well-known text string.
Since 1.0.0
Arguments
| Name | Type | Summary |
|---|---|---|
WK | string | The well-known text of the transformation step to create. |
Properties
| Property | Type | Nullable | Readonly | Summary |
|---|---|---|---|---|
IsInverse | bool | No | No | True if this transformation step instance is an inverted transformation. |
IsMissingProjectionEngineFiles | bool | No | Yes | True if any files needed by the Projection Engine for this transformation step are missing from the local file system. ArcGISHorizontalVerticalTransformationStep.ProjectionEngineFilenames indicates the required files. |
ProjectionEngineFilenames | ArcGISImmutableArray<string> | No | Yes | A list of the Projection Engine files required to support this transformation step. |
WKID | int | No | No | The well-known ID or 0 if the transformation in this step does not have a well-known ID. |
WKText | string | No | No | The well-known text of this transformation step instance. |
IsInverse
bool IsInverse
True if this transformation step instance is an inverted transformation.
Transformations have a specific direction that is indicated by the ArcGISHorizontalVerticalTransformationStep.WKText value. An inverted transformation is used to transform geometries in the opposite direction to that indicated by the well-known text. ArcGISHorizontalVerticalTransformationStep has ArcGISDatumTransformation.InputSpatialReference and ArcGISDatumTransformation.OutputSpatialReference properties that respect the inverse value of the contained transformation(s).
IsMissingProjectionEngineFiles
bool IsMissingProjectionEngineFiles
True if any files needed by the Projection Engine for this transformation step are missing from the local file system. ArcGISHorizontalVerticalTransformationStep.ProjectionEngineFilenames indicates the required files.
ProjectionEngineFilenames
ArcGISImmutableArray<string> ProjectionEngineFilenames
A list of the Projection Engine files required to support this transformation step.
Datum transformations can be mathematically defined (equation-based transformations), or may rely on external supporting files (grid-based transformations). For a grid-based transformation step, this returns a list of the files required to use this transformation, prefixed by an expected subpath of the file(s) underneath ArcGISTransformationCatalog.ProjectionEngineDirectory. For an equation-based transformation, this returns an empty list.
WKID
int WKID
The well-known ID or 0 if the transformation in this step does not have a well-known ID.
Occasionally, WKIDs may change, and an older code may be deprecated in favor of a new code. This property returns the new (latest) WKID code.
WKText
string WKText
The well-known text of this transformation step instance.
If this transformation step can only be represented in WKT2 format this property returns an empty string.
Methods
| Signature | Return Type | Summary |
|---|---|---|
Returns the inverse of this transformation step or null if the transformation is not invertible. |
GetInverse
ArcGISHorizontalVerticalTransformationStep GetInverse()
Returns the inverse of this transformation step or null if the transformation is not invertible.
Since 1.0.0
Returns ArcGISHorizontalVerticalTransformationStep
An ArcGISHorizontalVerticalTransformationStep representing the inverse or null if an inverse does not exist.
