Hi Bob -
I am fine with your comments and pleased that you revived Inquiry 2296. Anyway, beyond what I have said there about my preference for display type 'RGB Composite', I cannot see any difference to the other RGB display type.

Hi Bob - Sorry I have been misled by your 'derived fields'. I have been thinking of the explicitly named 'Derived' fields, that go eg with the grid formulas. Yes, I tired this formula. I ow understand the issue and everything works fine up to one point, we have discussed earlier on (with no clear an...

Hi Bob -

I am not using derived fields (cannot see derived fields anyway) as you describe in your second para. And then thing unfold as I described in my former email. McV is running under Windows 10 64-bit.

Hi Bob - I'm pleased that you could make good use of my RGB formulas. I have checked the 2 SVI formulas. They are not working properly for me, like: 1) I have used the path Imagery > JPSS Functions (Under Development) > VIIRS Natural Color SVI RGB 2) clicking the formula nothing happens (e.g. greyin...

Hi Bob - From my experience I would not re-scale and gamma correct the SVI Natural Colour RGB. The gamma correction should be done in the Layer Control, i.e. left to the user. I often find that I have to fiddle a bit with gamma, depending on what feature(s) I would like to have enhanced, e.g. (thin)...

Hi Bob - Sorry for this post. I have missed to look deeper into the RGB formulae that have recently been added for ABI, AHI, VIIRS (and SEVIRI). This makes my request obsolete. In the past I have used swath-to-grid to produce RGBs for VIIRS data by using my set of SEVIRI formulae like: data set > sw...

Hi - Some nightlies have passed since I processed VIIRS data. With the nighty of 22 Feb I see that the swath-to-grid method has been moved under 'Imagery > JPSS Functions ...', which is fine. However, it only offers the simple Image display types. 3 Color (RGB) Image (over topography) are missing. F...

Hi Bob -

First of all, I am sure that Europeans will be thrilled once the 0deg-meridian issue will be gone.
I am working in the Mercator projection. In my most recent case, I have been zooming on the Azores (spent gorgeous hiking holidays in September), i.e. zoomed west of deg.

best, HP

Hi Bob - Sincere thanks for your effort. I got your plugin working nicely with the first instance of the formula, be it in my configuration or when starting from scratch. The second instance delivers now the 3 lowest levels in the table without plottable data. However, I have discovered another prob...
