He or she meant by population I would assume. Approximately 5 vs. 10 million.

Population isn't very relevant when we're speaking specifically of things that relate to land area like topological maps.

But we aren't speaking of land area, we're speaking of buildings, which relate to population. I'd wager that LA County has more buildings than Finland.

Right. If one interpretation is wildly wrong and there is another blindingly obvious interpretation that is correct and relevant... Why would we ever give someone the benefit of the doubt?

Or refer to the community guideline:

Please respond to the strongest plausible interpretation of what someone says, not a weaker one that's easier to criticize. Assume good faith.

I wonder if I ever heard about Microsoft Maps before. What is the state of it? Who uses it? So I tried www.bing.com/maps. The first thing that surprises me is that it tries to set 5 cookies from google.com and one from www.google.com What is the reason for Microsoft to allow Google to track everybody who uses their maps?

I visited it's website, but didn't notice any google trackers. I'm using Privacy Badger btw. Maps app is also automatically installed on every windows 10. I think they partnered heavily with here maps in the past.

In the Netherlands the businesses (shops, restaurants, and general businesses) are more complete than OpenStreetMap, but not as complete as Google because everyone sees Google as the de facto standard and they push owners to add their info in the de facto Google search.

Bing Maps is fast and responsive (unlike Google Maps on anything other than their own, proprietary platforms such as Google Chrome, the Google Maps app, or Google Earth), and has aerial imagery and traffic info (unlike OSM).

Bonus game: turn off labels on satellite view, zoom out to world view, and try to find your house or other places. Surprisingly hard!

It should be trivial. It should be standardized. It is absolutely bizarre that we need to rely upon commercial companies to map things like streets and buildings when this is very accurately tracked by government. In an ideal world OSM data grids could be delegated to the appropriate governments, where it could have perfect precision with changes, street closures, one ways, redirects, etc.

It should be trivial. It should be standardized. Your use of the word "trivial" indicates you've never worked on complex GIS systems. Whether it should be standardized is a matter of debate. Currently, each county or state or municipality uses the software and standard that suits its needs, and more importantly -- it's budget. The GIS needs of New York City are not the same as the GIS needs of Saint George, Utah. Sai…

"Whether it should be standardized is a matter of debate."

In the same way that vaccines are `debatable'. To export an accurate, up to date model of roads (and road data) and optionally building layouts should absolutely be the norm.

Nor does a standardized export format necessitate using a single uniform GIS solution, of which I've had to inter-operate with a number.

The real world digitizes spectacularly well, a lot of people just make poor choices and make excuses (or worse, buy nonsensical excuses) for not helping in getting there.

Out of curiosity, I wonder if this data dump includes "sensitive" buildings? eg things that would generally be blurred/missing/etc on OSM for various reasons.

If it is visible in the imagery they analyzed it wouldn't be intentionally left out of OSM without some superseding information that it didn't exist anymore.

Makes sense, thanks. :)

But we are talking about building footprints which DO directly correlate to population, not overall area of an entity. So it's the most relevant factor.

Not really

Arizona and Croatia have the same population, but look at the aerial maps...
