ICompositeGeoTransformation Interface

Provides access to members that control a set of geographic transformations.

Sometimes it is necessary to transform between two geographic coordinate systems where a direct transformation does not exist. A composite geotransformation allows you to create a 'chain' of existing or custom transformations. Each transformation in the set must have its direction set properly.

Name |
Description | |
---|---|---|

Add | Adds a geographic transformation to the list. | |

Count | The number of geographic transformations in the list. | |

GeoTransformation | A geographic transformation from the list. | |

GetSpatialReferences | Returns the from and to spatial references for the transformation. | |

Name | The name of the geographic transformation. | |

PutSpatialReferences | Sets the from and to spatial references for the transformation. | |

SetEmpty | Clears the list of geographic transformations from the object. | |

TransformationDirection | The direction (forward/reverse) of a geographic transformation. | |

TransformMeasuresFF | Transforms floating point measures to floating point measures (or do the inverse). | |

TransformMeasuresFI | Transforms floating point measures to integer measures (or do the inverse). | |

TransformMeasuresIF | Transforms integer measures to floating point measures (or do the inverse). | |

TransformMeasuresII | Transforms integer measures to integer measures (or do the inverse). | |

TransformPointsFF | Transforms floating point points to floating point points (or do the inverse). | |

TransformPointsFI | Transforms floating point points to integer points (or do the inverse). | |

TransformPointsIF | Transforms integer points to floating point points (or do the inverse). | |

TransformPointsII | Transforms integer points to integer points (or do the inverse). |

Interfaces | Description |
---|---|

IGeoTransformation | Provides access to members that define a geographic (datum) transformation. |

ITransformation | 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. |

Classes | Description |
---|---|

CompositeGeoTransformation | Performs a sequence of geographic transformations. |

Of the **ITransformation** interface, only the **TransformPointsFF** method is implemented.
