Hi Community,
I get this question often from our collection team, do you guys have a suggested overlap?

Hi Justin,
Yes, however, important to note that the optimal values for overlap (between successive images) and sidelap (between adjacent flightlines) are governed by photogrammetry principles, not Correlator3D. however please find a reference below:
For medium/large format cameras mounted on aircrafts, the overlap should be at least 60% of the image size. The recommended sidelap is 30%.
For small cameras mounted on drones, the recommended values for overlap/sidelap are 70%/50%.
