This script uses eumetsat satellite imagery API to download satellite images and display it in a image viewer.

This is sort of a draft, but it fetches images of the last 10 hours of Dijon, France (ie: roughle POS=45.2,2.75,49.3,8.25). It also adds three subsequent layers: 1 layer for colours (rgb_geocolour), 1 layer for city labels (osmgray:dark_labels, so you know what you are looking at.), and one layer for rain precipitation (msg_fes:h60b).

Once the images are downloaded the image viewer opens and cycles them in a slideshows.

Dependencies

• imv
• dbus
• dunst

PS: I chose imv over feh for image viewing, as imv has slideshow supports (and also gif), which feh doesn't have.
