Sets the Ground Control Points (GCP) on a raster with the specified Column (pixel), Row (line), X Coordinate, Y Coordinate and Z Coordinate.
If the raster has already set GCPs, the old GCPs will be overwritten.
Parameters
Source Coordinate System
This parameter indicates the coordinate system that would be effective if the Ground Control Points were applied. This is not necessarily equivalent to the coordinate system of the feature.
GCP Value
A string value specifying the GCP(s). Each GCP is separated with a semicolon and each value of a 5-value GCP is separated by a space.
To set a GCP
- Set the source coordinate system.
- In GCP Value, you must enter 5 values, separated with a space: Column(pixel) Row(line) X-Coordinate Y-Coordinate Z-Coordinate. For example,
1 10 50 -20 0
- To set multiple GCPs, you can use a semicolon to separate each GCP. For example,
1 10 50 -2.5 0; 2 4 6 8 10; 1 2 3 4 5
Usage Notes
This transformer is unaffected by raster band and palette selection.
Editing Transformer Parameters
Using a set of menu options, transformer parameters can be assigned by referencing other elements in the workspace. More advanced functions, such as an advanced editor and an arithmetic editor, are also available in some transformers. To access a menu of these options, click 
beside the applicable parameter. For more information, see Transformer Parameter Menu Options.
