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.
