Plus how often is that declassified images released, they don't say nor could I find any info on that. Not as often as a orbiting satellite with a contract I can tell you that much. Whatever, I succeed or whatever the English word for give up is. Okay sweety, the meds are kicking in and I need to sleep. Goodnight, sleep well you guys.
The imagery wasn't declassified the mathematical algorithms were declassified. The imagery is generated similarly to most of Google's data, low level aerial photography.
Actually, satellite imagery data isn't very effective on a massive scale at high resolution. Satellite imagery is effective at low resolution but satellites move too fast to capture images of large cities rapidly especially with the resolution Google (or Apple) require. Google is likely using the satellite imagery to remove artifacts (clouds) and obtain low resolution views.
I was able to research and discover that Google is using the satellite data for high resolution images of specific structures, typically points of interest.

Then there is the issue of coverage. Has C3 and/or Apple done flyovers of all roads in the US or just the major cities at this point? It seems to me that basic satellite coverage will have to intermixed with the C3 tech which I think is why they have acquired so many mapping companies.
Just visit the Nokia Maps website. Apple (formerly C3 Technologies) has photorealistic data.
Please understand that the Apple technology can generate images from virtually any angle viewing virtually any direction at many different altitudes including a "street view."
Apple doesn't need to do aerial photography of the entire Earth at this point, they already have licensed the data just like Google. The architecture and execution is highly complex for an amazingly simple concept:
Placebase = Google Maps with high customization and incredible APIs
Poly9 = Google Earth prior to Google SketchUp (Google's 3D modeling program)
C3 Technologies = Google Earth with Google an automated high resolution version of SketchUp
In other words, Apple has 2D and 3D map data for the entire planet just the same as Google. Much like Google, Apple has high resolution 3D images of a very small percentage of the planet and such data is typically for very large metropolitan areas the difference is that Apple's data is rendered via advanced mathematical algorithm rather than partially by hand.
Apparently, Apple is using Waze for crowd-sourced traffic data.
If you compare the data you will see that Google SketchUp provides a building facade rendered using a partially manual 3D modeling technique while Apple's technology renders the data automatically. Google Earth may render trees somewhat better but many buildings aren't rendered at all since the effort is partially manual. Apple's technology is virtually 100% automated with similar quality but once an area has been rendered the entire area including all structures are rendered.
