Collect spectra of averaged windows (3x3-or-5x5 or arbitrary)

[aloboa]

Where did https://bitbucket.org/hu-geomatics/enmap-box/issues/288/spectral-libraries-select-3x3-or-5x5 go? I have a note stating:

• It’s already implemented in the current development branch and will be released with the next EnMAP-Box version 3.5. That looks like a comment by jakimowb, but cannot find how to actually do it (not mentioned in the doc) and there is no track of this issue in github.

I actually found it but...

This option is too much hidden under: View/Panels/Spectral Profile Sources/SpectralLibrary 1/Sampling/Kernel/3x3 or 5x5 or 7x7

I suggest:

1. Spectral Profile Sources should also be an option on the right click of "SpectralLibray 1"
2. The level "Kernel" is useless, it could be omitted, and just select 1x1, 3x3, 5x5 or 7x7 directly under Sampling
3. The Sampling options should also be directly accessible in the "+" of Add profiles.

Also, outside the sampling options Could it be possible to add a specific tool at the main menu horizontal bar (the one with the hand etc) to draw polygons and get average (+/- sd) profiles?

Yes, that sounds reasonable.

2. The level "Kernel" is useless, it could be omitted, and just select 1x1, 3x3, 5x5 or 7x7 directly under Sampling

Not sure, how would you select the size and the aggregation function in one line?

3. The Sampling options should also be directly accessible in the "+" of Add profiles.

Also not sure, because you can have multiple spectral views with different sampling options.

Also, outside the sampling options Could it be possible to add a specific tool at the main menu horizontal bar (the one with the hand etc) to draw polygons and get average (+/- sd) profiles?

Could be useful.

@jakimowb, please decide, what is possible to implement.

@aloboa we had to close the bitbucket issue tracker. It got flooded with with spam issues and bibucket never reacted to this problem.

I like the idea of simplifying the menu. I'll also simplyfiy the backend API that it becomes easier to register other sampling methods.

Any roadmap to include this feature request?

Hi @aloboa, note that in the Profile Analytics tool, you have the option to plot the average profile under a polygon. See #261.

Also note, that you can forward profiles plotted in the Profile Analytics tool to a Spectral View.

Those are certainly useful, but I refer to the task of interactive collection of spectra. Doing at pixel level is normally too noisy, and being able to optionally set a larger window would be much appreciated.
