You are here: Rasters > RasterGCPSetter


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.


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.
