Why are old satellite images black and white? The infographic below provides a better idea of when the launches and completions occurred. The others are still on-orbit enriching historical collections with the latest remote sensing data (optical and radar). Landsat 1-5 have completed their missions, contributing to the precious database of historical satellite imagery. Later, Landsat’s Earth observation initiative was supported by Terra and Aqua MODIS (NASA and USGS), Sentinel-1 and Sentinel-2 (ESA), CBERS (China and Brazil governments), and more. The last ones, Landsat-7 and Landsat-8, have been operating since 19, respectively. Six more Landsat satellites joined their predecessor over time thanks to USGS and NASA to provide glimpses from space every 14 to 16 days. The oldest of them is dated 1972 when Landsat-1 was launched. It can flaunt the biggest data collection so far (billions of historical satellite images). The Landsat program is the longest-ever mission that has been retrieving imagery from space for over 50 years by now.

Or Apple could have an in-country license that is enforceable only via the web interface. Apple may have a web license for this specific set of data but not an app license. Since Apple's web maps are practically unknown, they don't have much usage and can support more frequent updates.Īnd there could be licensing issues. Different interfaces may have access to different data that hasn't been globally distributed yet. Apple maintains global content distribution systems. Or rather, the people who care about those lower levels of detail aren't using any Apple tools for their needs. But nobody cares about lower levels of detail. So the data will get a lot better if you zoom in. People are generally only interested in looking at their house. Those satellite maps are useless with junk data. I would rather have a bit of dissonance between the different views (Explore, Driving, Transit, Satellite, 3D) if at least one of the views had current information! O'Hare Terminal 5 (Explore View on Maps.app on Sonoma) What bugs me the most is that Apple is even holding back current information with the views that they have complete control over (Explore, Driving, Transit), showing us out-of-date information: O'Hare Terminal 5 (Satellite View using DuckDuckGo on Edge on Windows 11, Parallels) I never knew that Apple has an updated satellite view: O'Hare Terminal 5 (Satellite View on Maps.app on Sonoma) I had to check on Google Maps to understand what had happened. Little did I know that an expansion of the terminal had occurred. When I looked on Maps on my iPhone, the gate was floating out in the middle of the tarmac. I have no idea why Apple does this either, but it seems really short-sighted if they're only doing it to preserve the 3D transition, at the expense of up-to-date information.įor example, earlier this year I flew into O'hare International Terminal 5. Since that super-high resolution 3D data is much more difficult to get, that means that Apple's moderately-high resolution data is probably always going to be older than it would be on the web, where there is no 3D view. But once you get low enough to where you could compare with 3D, Apple is going to use data that matches the 3D data. They don't seem to mind the significant changes in imagery at a lower level of detail. (Due to my farm field theory, I can't confirm it is newer.)īut my point is, I think Apple is making a point to use imagery that matches its 3D views, even if that is older. I now know it's old data, but 3D! Cool! But if I zoom back out, eventually I get a lower-resolution version that looks more like the web version. But they are most definitely different imagery.Īctually, I see a new building in the web version, so that's definitely newer by at least the time it takes to build a new building.Īnd maybe I have another category - Apple is its own worst enemy.Īs I zoom way in using Apple Maps, I eventually get to a 3D view of this scene. These could be farm fields where one just happened to be in the middle of harvest that day. I don't know which of these is more current. Same location, using Apple Maps, the App, on Monterey, from Canada: But at a different level of detail, on a different network, connected to a different CDN region, possibly on a different platform, web browser, etc., all bets are off.ĭuckDuckGo, using Apple Maps, in Safari on Monterey, from Canada looking at the outskirts of Prague: I'm not disputing that you see no difference in two specific images.
