I'm about to make a first try of an ortho-mosaic aerial image of an area about 600m x 600m.
I plan a forward overlap of about 80% and a sidelap of about 60%.
Does that sound reasonable?
Which shutter speed is appropriate for AGL=150m, v=10m/s, f=20mm?
The area I'm about to map is not totally level, AMSL is between 500m and 580m.
For optimal post-processing, shall I aim at constant AGL or constant AMSL?
I also appreciate any other beginner's hint(-s).
