The map tile backend is in the middle of a multi year effort to migrate from the Flippity Service to the Floopity Service. The FlippityFlooper was believed to have finished the necessary format conversions for all map tiles in the US and Canada but 5% of the data sources were missed due to a bug that was discovered after the creator of FlippityFlooper had been promoted and changed teams, so those Floopity tiles are f…

Why would the island need underground structures at each corner?

Backup power generators? Security control room? There are tens of reasons why you'd put some parts of your estate underground

>why you'd put some parts of your estate underground

My question was more about the specific combination of 1) underground 2) in each corner.

I can come up with a plausible reason for either, but not in combination

I guess it's storage, sensors and microwave links. On one corner you can see a concrete pad where a small boat can land unseen from the mainland. There are some official helicopter flyby videos but all of them fail to capture this one particular side of the island.

It's like a CIA naval base for drug smuggling.

Google is not flying over the area itself right? perhaps they where using source maps with some sort of license agreement and the license expired, or there was a dispute. It seems to me that it is in the favor of Google to gather the most up-to date maps, even if they can offer them in a limited window. I wonder if the same is true for Google Earth, since I believe that uses higher quality / different maps in a lot o…

Occam’s razor would suggest someone at Google took it down. I’m not sure we need to reach for convoluted explanations to explain things.

Altadena is part of unincorporated LA County, they don't vote in the City of Los Angeles elections.

Palisades fire damage has also been removed from the mapping.

Must only be for US users. When I look at it from Australia the Palisades damage is still there. Altadena also shows mostly vacant and cleared lots.

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.

The most unfortunate thing about Google's 3D photogrammetry is that they don't allow you to view historical captures, as they only serve the flattened 2D version there. For the time being, the only resource for these captures are various Microsoft Flight Simulator addons where people dumped Google's photogrammetry data to add scenery not included in the built-in photogrammetry coverage.
