Copernicus browser allows to browser images of the earth in quite high resolution (I think up to 20x20m) refreshed every 3 days or so and it's absolutely cool to be able to use different views such as nir, swir...
I think the delay must be much longer than 3 days, since Iceland and Norway are still shown covered in their winter coats. Really interesting tool though.
Hmm, there is no delay. Iirc the full cycle (sattelites return to exactly same spot in relation to earth) is about 10 days and most paces get crossed in 1-3 days.
