Alternative Satpy scripts

• One script for each satellite type, e.g. one for MSG2,3,4; one for Metop-B,C etc.
• Mandated options for Date and (for LEO's) day/night pass have -t and -dn options
• Other options for area, composite, source location, destination location,output filename etc.

Content:

• GEO scripts
• LEO scripts
• Selector (gui)
• Visualizer area's (gui)

The GEOstuff.py available here is very similar to the original one, but it contains support for:

• native MSG format
• out-of-service sats like MSG1
• HIMA9 added
• HIMA: mixed compressed an not compressed (no need to define decomp in HIMA.py)
• Stop processing if needed channels are missing
• search rule of MTI1 adapted
• Besides 'area' (string) geo_images() also accepts struct. sarea from satpy's get_area_def()
  this is for resizing for movie frames; sarea contains also new size of image to generate
• selection for movie or not (-m commandline parameter), including resizing and adapting subdir for generated files

• satpy_selector_20230423.zip
  

• GEO scripts
• LEO scripts

Now:

• Select type of satellite, this will refresh the list of available data
• Select a line in the list of available data
• for polar sats choose day or night
• choose an area (default=built-in defaults in the used script)
• choose a composite (default=built-in defaults in the used script)
• click 'View', will generate an image and open a viewer
• Or click 'Gen', will only generate an image

satpy_selector.py contains 2 lists of satellites including the command to execute them:

• geosattypes
• leosattypes

• exe_cmd=''
  • This executes scripts like MSG.py. The scripts must be at a location included in the searchpath and must be executable
• exe_cmd='python3 <full_path_to_scripts>'
  • This executes scripts like python3 /home/user/tools/MSG.py (if <full_path_to_scripts> is /home/user/tools/)

satpy_selector.py uses lists defined in satpy_settings.py:

• data_loc: contains name and location of files. Name may be any name you like; location must be full path. A location normally should contain data of one satellite, but may also contain a mix of different satellites.
• regio_list: this list contains area's bound by min/max lon and lat. It is used to divide the very long list of area's, defined in the areas.yaml files, into manageble portions. You may adapt this list, including names and area def's. The result is used to create a 2-steps menu 'area' in satpy_selector.py:

  

• composite_list: list of available composites for each satellite. This list may be adapted/extended; not all composites may be added yet.
  The Composite menu is created/adapted if another satellite is choosen.

New:

If a polar satellite is choosen and earthmap.gif exists then the track and selected area will be shown:

Location of files

• The main .py files (MSG.py, Metop.py etc.) are all executable. You may put them in a location pointed to by searchpath (Linux: $PATH) and then execute them from anywhere like:
  • Metop.py -t .......(etc.)
    
  Or:
  • python3 <path_to_py>/Metop.py -t .....
  in which case you need to add the location of the .py files.
• Files used by the main .py files need to be put at the same location:
  • GEOstuff.py, LEOstuff.py

(Note: this is also implemented in the satpy_selector, which shows then both track of selected satellite and selected area.)

Usage:

  -h, --help  show this help message and exit
  -s S        size (multiplier fact.) image (1=org. size)
  -f F        plate carree image file
  -ac AC      colour area
  -m [M]      use menu instead of buttons
