Georeferencing a raster on GCP basis

A

HI everybody,

is it possible to georeference a raster image without the four border coordinates (I already checked the "Georeferencer") ? I have several tiff files and within the image I`ve got four GCPs with image and world coordinates. I would like use these GCPs to georeference the images.

One approach I tried was to set the 4 GCPs in the image with the RasterGCPSetter because the documententation for Ground Control Points says "GCPs can either be applied to the raster resulting in the image being georeferenced and tagged with the GCP coordinate system" Unfortunately I can't perform this last step of georeferencing on basis of these GCPs.

Is there a way to perform this task?

 

Thanks in advance

Annika

There is a transformer in the hub called RasterGCPApplier, I've never used it, but it sounds like what you need.
