Separate chunks or groups in one chunk - your opinion

[Damian]

Hello

I want to ask you how you organize your work. I have photos taken by one UAV, same camera, but in few separate flights one after another (due to battery change). The number of photos is around 1500. Is it better to create a separate chunk for every flight or just to put photos in "Camera calibration" into groups within one chunk?

In addition, there is an overlap (around one-two rows) between flights.

How do you process such project?

Thank you for answers!

Anyone would like to share his/her experience?

Hello Damian,

If the individual flight have considerable overlap with each other, the GSD is more or less similar for all flights and the conditions are also similar, then you can run alignment for all photos in the single chunk at once. Usually it's better, as the shouldn't be reconstruction artifacts in the flight overlapping areas that could appear in case of individual per chunk processing. Also if you are using control points you would be able to use the complete set of GCPs for the whole area.

Splitting the calibration groups may be reasonable in case of low quality optics, zoom lens and after hard landing.
