Why repeatability matters more than a beautiful 3D model
A model that cannot be compared to the next capture is a presentation asset, not a project record.

The first capture of a site is often the prettiest one, because nobody is comparing it to anything. The second is the one that earns its keep — and it only works if the first was planned with the second in mind.
What has to stay constant
Coordinate reference system and control or check strategy
Coverage extents and buffer, so the comparison area is the same
Capture geometry and altitude band, within reason
Seasonal and lighting conditions where vegetation or shadow matters
Key takeaway
Plan the second capture during the first one, or the comparison will not hold.
Corridor work is priced by logistics, not airspeed. Access, repositioning and mobilisation dominate the cost structure long before the aircraft matters.
