update app/boot.py

Add flag --texturing-skip-global-seam-leveling since I've seen a number of multispectral datasets processed without this and folks thinking our processing is broken due to getting out of range values.

[pierotofy]

This requires some thought, as in absence of proper metadata the radiometric calibration doesn't work, but skipping the global seam leveling will cause seam visibility.

Ugh... Multi-spectral is fun.

What approach sounds reasonable?

An allow-list of known working sensors we pass it for?

[smathermather]

I don't know what folks expect on the drone side, but on the satellite multispectral side, showing seams is an acceptable alternative when adequate reflectance corrections aren't available.

[Saijin-Naib]

It seems that the sUAS expectation is that it "Just Works ™"

[pierotofy]

I've received complaints when seams were present.

[Saijin-Naib]

If returns count as complaints, it is non-zero for this...

[smathermather]

Complaints that we weren't blending by default or complaints that there was a way to bypass blending? The latter would be a strange compliant, but I suppose we've seen stranger.

I'm surprised academic users haven't complained that we are blending without a method for bypassing. There should always be a way to bypass blending for scientific use cases.

But anyway, I have no skin in this game at this time, so 🤷.

[Saijin-Naib]

Complaints that only our software has seams and no others do 🤷

I absolutely agree we should keep a way to not blend, but it appears more of our users expect it.

Random Postscript: super interested in the separation of illumination from surface color we see in neural applications. I would love to see incorporation of proper brdf (or modern equivalent) into in quantitative drone imaging. No idea if anyone is working in this space, and I currently have no use cases myself at this time.

[Saijin-Naib]

Thanks for the manual calculation of BRDF PTGISD. I had buried that 🙃

[pierotofy]

I'll close this, as we should continue blending by default.
