I don't know how the political boundaries were drawn. WYSIWIG. What you see is what I got. As the raw image comes in --- and it appears high resolution, like a very high resolution B&W photo
, there are no political boundaries. As I am typing this, the computer is imaging NOAA 17 again. I will post the raw image.
The version of WXtoImg I use last is the free version. The next step up at 60USD does even more filtering and can create 3D images you can use special glasses with.
The program is (nearly) fully automatic. It will even auto-update Keplerian elements! The unprocessed image has a weird visual quality to it. But once the satellite passes and the signal is lost
, the program goes to work (automatically) and starts running filters of gamma, contrast, and all sorts of Photoshoppian terms and you get some damn pretty images.
I sent the initial NOAA 17 image to Volker in Germany
whose company (or maybe he is a clerk, I dont know) makes the APT-06 and he said the image was very good -- which means that I installed and shaped the antenna
correctly. Maybe he was just humoring me.
I have included the image that came in during this post.
The first image shows both channels. That is the raw image -- channel A and B.
The image to the right is a "MSA Multispectral Analysis" "MSA Multispectral analysis (NOAA-# 2-4) Multispectral analysis. Uses a NOAA channel 2-4 image and determines which regions are most likely to be cloud, land, or sea based on an analysis of the two images."
The image directly below the raw dual image is a "MCIR map color IR" image. "MCIR map colour IR (NOAA) Colours the NOAA sensor 4 IR image using a map to colour the sea blue and land green. High clouds appear white, lower clouds gray or land/sea coloured, clouds generally appear lighter, but distinguishing between land/sea and low cloud may be difficult. Darker colours indicate warmer regions.
To the right is the "Daylight Sea Surface Temp" image. "Daylight sea surface temp (NOAA) Creates a false colour image from NOAA APT images based on sea surface temperature. Uses the sea surface temperature derived from just the sensor 4 image to colour the image. This is less accurate than the sea surface temperature derived from sensor 3-4 sea enhancement, but is available when the 3-4 image is not available. No attempt is made to distinguish cloud or land from sea. The sea surface temperature may be incorrect due to the presence of thin or small clouds in the pixel evaluated, or from noise
in the signal."
The final image is a "NO colour IR enhancement (GOES/NOAA) NOAA colour IR contrast enhancement option. Greatly increases contrast in the darker
land/sea regions and colours the cold cloud tops. Allows fine detail in land and sea to be seen and provides a very readable indication of cloud top temperatures. This enhancement option is temperature normalised" That image is from NOAA 15
There are so many different filters and combinations of channels you can do with the software -- infrared, sea temp, veg temp, contrast, multispectral analysis, false color enhancement and more. And all this is just on the free version!
Anyways, mods, I won't post anymore images here -- I suspect I may be violating bandwidth rules. And I get this sense that I am a little afield of sailing! But.... the path led here for me.
