I used OSM tiles when creating webmaps sometimes and they can be great.

That said it’s coverage is inconsistent. This area around a highschool has really high detail footprints for the houses so I think it might have been part of their IT class at some point.

Meh.

It’s doubling each step.

If course it’s at 1/(2^n) of the final volume at n steps before the final step.

• At half of its final volume one step before the end
• a quarter of its final volume two steps before the end
• an eighth of its final volume three steps before the end
• a sixteenth of it’s final volume four steps before the end
