A transformation that approximates other transformations.
ApproximateXform is used to approximate a GeoDataXform to achieve a better performance and it is mainly used for those GeodataXforms that are computationally expensive, such as CoordinateXform, AdjustXform, and etc.
ApproximateXform approximates its base GeodataXform by applying the true transformation only on a coarse mesh, and performing bilinear interpolation for between points. ApproximateXform guarantees the approximation error does not exceed the specified tolerance.
| Interfaces | Description |
|---|---|
| IApproximationXform | Provides access to members that control transformation approximation. |
| IClone (esriSystem) | Provides access to members that control cloning of objects. |
| IDocumentVersionSupportGEN (esriSystem) | Provides access to extend the IObjectStream interface with methods to hande saving objects that did not exist in previous versions of the software. |
| IGeodataXform (esriGeoDatabase) | Provides access to members that control geodata transformation. |
| IGeodataXform2 | Provides access to additional members that control sensor specific geodata transform. |
| IGeodataXformApproximation | Provides access to members that control approximation for geodata transforms. |
| IPersistStream (esriSystem) | |
| IRasterXform | Provides access to members that control raster specific geodata transform. |
| ISensorXform | Provides access to members that control sensor specific geodata transform. |
| ITransformation (esriGeometry) | Provides access to members that apply a function (or its inverse) to a set of points or measures. The suffix of each method indicates the type of parameters operated on. |
| IXMLSerialize (esriSystem) | Provides access to members that XML serialize and deserialize an object to/from XML. |
| IXMLVersionSupport (esriSystem) | Provides access to members that help in serializing an object to different namespaces (versions). |
