I have about 35 square miles of orthorectified, high resolution, aerial imagery that is broken down into 620 individual tiff files. I have created a mosaic dataset of the imagery and I am working with ArcGIS 10.5 with all extensions.

I need to increase the accuracy of the imagery placement as the imagery was collected without the use of ground control and there are (x,y) errors of 1 to 3 feet across the area. I do have hundreds of ground control points that are survey quality and are visible throughout the imagery. I also have a high accuracy DEM for the area created from LiDAR data, however, I really do not need to fully orthorectify the imagery again but rather just slightly spatially adjust the data.

Is there an ArcGIS tool available to correct this imagery?

I did look into using Bundle Block Adjustment but I am not sure if this is the best approach for the needed correction.

    If georeferencing accept mosaic dataset as input, I'd work with whole set. Individual adjustment different to simple shift will distort edges. – FelixIP Sep 20 '17 at 21:46
  • You could use the Georeference toolbar resources.arcgis.com/en/help/main/10.2/index.html#/… but you may need to export the mosaic dataset to a single raster first. Perhaps an affine will be what you need (rotate & scale) but other methods are available (2nd, 3rd order and adjust) to transform the raster but @FelixIP is 100% correct that any other transform will render anything outside your control points subject to an uncertain transformation and no longer trustworthy. – Michael Stimson Sep 20 '17 at 23:34
