Turn APT images into HRPT-like composites. No overlays like WXtoIMG, no weird underlays, or requiring where the satellite was when the image was taken. As an example to the power of this tool, take a look at the header or the gallery below.
Neat, huh? Anyways, here's how to use it :)
After seeing too many black and white ugly images. Moving on.
Coming soon! It is quite complex, though, so it may take a while. While you wait, get an HRPT setup.
Essentially, the visible channel gets too bright. When making an HRPT composite, standard 221 is used, and the channel 2 increases along with the channel 1. But on APT, there is no channel 1, so channel 4 is used, however, it becomes ugly in terms of brightness. Essentially, a good idea is to try to get NOAA-18 APT, or try not to get too much varying brightness in channel 2.
There is a single script that seperates channels from a raw APT image, and uses the channels to create the final composite. Both the two channels and the colored image are available in the out/ directory.
$ python ./src/makeRGB.py --help
usage: makeRGB.py [-h] [-m MODE] [-b] src
APT Colorizer CLI
positional arguments:
src The raw APT image taken from the satellite
options:
-h, --help show this help message and exit
-m MODE, --mode MODE The mode. It can be "ir", "ir_night", "sunset", or "noir" (default: noir)
-b, --boost Boost the land color on very blue images (default: False)
python ./makeRGB.py input.png --boost --mode noir
