Not entirely related, but Google Maps is still showing satellite images from 5 years ago in Paris, one of the most visited cities in the world, and it's not even updated once a year. I don't get it.
In Germany it seems to have moved to the 3D photogrammetry data for anything with pixel sizes smaller than a car; is that maybe also the case for Paris?
I do understand that it's sad they don't calculate orthographic images from that to replace their satellite views in these areas though; full 3D is severely more resource intensive on the client after all.
Visited Lisboa last summer, the building where I booked an apartment was not even there in Google Maps, satellite image data was showing a leveled site with some dumpsters.
Just checked and the images are still the same old ones...
I wonder if there actually does exist updated to-the-minute imagery of various places, just not from sources publicly available on platforms like Google Maps?
It must be quite valuable data. One anecdote I heard/read somewhere was that firms often use satellite imagery of parking lots (over time, as one measure among others) to gauge how popular a place is. I don't know if it's true or not.
For Epstein island the US government has scrubbed/redated large periods of historic satellite imagery in order to hide construction of underground structures on each corner of the island. Chinese equivalents of Google earth offer clear images of different construction stages that the "US Coast Guard" prefers to hide.
If you check different satellite imagery providers it's always interesting to see what time periods are even available (paid or free), and if the imagery from an earlier date has been re-labeled to suggest it was taken at a later date.
