I am very curious if anyone who have done a lot of georeference projects. Wheather they be old photographs, or the list from this : http://desktop.arcgis.com/en/arcmap/10.5/manage-data/raster-and-images/list-of-supported-raster-and-image-formats.htm

 

So if you work on them, do you work a lot of control points or just depends on the image itself ?

 

Would a few control points be sufficient or more than control points is better ?

 

I wanted to grasp to get the idea of what others are doing with georeference with how many control points out there .
