Genuinely asking, how do you make something like their map view accessible with so many objects and layers? I'd imagine you end up with a solution that exposes various content rectangles and ignores everything else, kind of how Google Maps does it.
Not all of accessibility is for those who cannot see (well). WCAG also has a bunch of guidelines for loss of dexterity and other ailments:
• keyboard support (being able to navigate to all controls as needed, not being stuck in a navigation island from which there is no escape with the keyboard, etc.)
• pointing device considerations (not requiring drag unless absolutely essential, no action on mouse-down, etc.)
• not requiring the simultaneous use of mouse and keyboard (e.g. via modifier keys)
• sufficient size for buttons and other pointer targets
• the ability to suppress animations, flashing images, etc.
• the ability to control colors and contrast of things on the screen
...
Of course, something like Photoshop, Illustrator, or the visual part of Google Maps is hard to use when you cannot see, but there are so many different disabilities that some or even most accessibility guidelines can apply to pretty much any software.
