One click: the AI finds the changes, then you get a movie of them.
The AI reads exactly what the map shows now, square in the middle, and reports changes per grid cell. Takes 20 to 60 seconds.
Search a place to list its photos.
How this works, and its limits
Source. Esri World Imagery Wayback: every version of Esri's satellite basemap since February 2014, kept as dated releases. For the spot you pick, the tool asks the archive which releases actually hold a different photo, then asks Esri's metadata for each photo's capture date, resolution and provider (mostly Maxar).
Zoom matters. The dated high-resolution photos usually live at zoom 16 to 18. Zoomed further out, both sides can show the same coarse mosaic; further in, there may be no archive tiles. When both sides are the same photo at your zoom, the tool tells you.
Dates. Each date is the day the satellite took the photo, from Esri's own records. Loading them can take a while the first time anyone looks at a place; after that they are instant. If Esri has no record for a photo, it says "Date unknown".
Not every change is there. Esri updates a place when it has new imagery, which can be years apart. The archive holds what Esri published, not every image a satellite took.
