I am trying to georeference a number of drone jpg images using the georeferencing toolbar. I only have a set of 4 GCPs per image which pretty much limits me to either the Affine or the Projective transformations which I have decided to use the latter. Before starting the actual georeferencing I have created a world file for each image so that they will locate to their coordinates found in the exif header and then I will manually georeference the images from there. My problem is that once I create my four links and select the projective transformation the raster will disappear. Zoom to layer does not display the raster either. I've done the same process but without creating the world files and the transformation works fine. Is this happening because of the pre-existing world file that I created? Using the Affine transformation successfully completes but I would like to know why the Projective one is not working. I've tried both updating georeferencing and rectifying and both options have the image disappear.
