Ocean indices branch: OSI, PI and FAI

[EmanuelCastanho]

Added to the water domain: Oil Spill Index, Plastic Index, and Floating Algae Index.

PI spectral index is identical to IPVI, but the applications are different. I do not know how you handle these cases.

I added lambdaS1 because of FAI. This spectral index also uses lambdaR so I think it makes more sense to change the description of the lambdas. I changed the description to central wavelength in different files.

Tests OK.

Closes #50

Nice work!

Please just update the DOI of OSI and it will be ready to be approved! ;)

[davemlz]

The DOI is not working. Could you please update?

[EmanuelCastanho]

You are right, it is giving Error-Cannot Connect to Server. The DOI comes from ResearchGate.
There is this one https://doi.org/10.1016/j.mex.2021.101327, it is a paper from the same author, uses the same band ratios (see Conclusion), but does not explicitly mention OSI.

I suggest:
a) Using this different paper;
b) Commenting this index until the OSI DOI is back again.

Thanks :)

[davemlz]

I just checked. The first DOI is for the poster. In the poster the authors reference the new DOI you sent. I also checked the Conclusions and there it is the ratio. I think it's fine if we keep that last DOI and make the index available ;)

Also, there are conflicts in indices.py, this is because new indices were just added, but not a major problem, just sync the branch ;)

[EmanuelCastanho]

Please confirm if everything is ready :)

[davemlz]

Just a small error. I added a suggestion, you can commit it and it will be done! ;)

[davemlz]

I realized I could commit it myself. I just did.

[davemlz]

Merged!

The indices will be available in the new version of ASI. Thank you very much for your contribution!

Cheers,

David
