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 survey quality ground control points that 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 any 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.
1) Would I need to create a full raster from the mosaic data to do the correction? Each TIFF is about 100MB so that would be about 62GB for the whole area.
2) Typically, how many ground control points are utilized to correct an area this size.
