It would be very useful to have a AT image filtering tool that allows the user to filter images based on several metrics after a successful AT. For example, if we have a very high level of image coverage observing the same point, it would be useful to remove some of the images so we have a target level of coverage. E.g. a tie point is observed by 4 or 5 images, rather than an excessive number. The filtering could be completed on sequential capture, keep first, keep last or keep smallest GSD. Agisoft has a reduce overlap feature which essentially does the same thing.
