The heights seem all over the place. Look at the WTC, for example.

#43What is the crowd process to upgrade/correct this? I notice massive errors in small Midwest US towns (multiple buildings being combined/ommitted, etc)?

It's machine-learning generated "slop" honestly.
Looking at where I live and where I grew up the building heights are quite badly estimated.
- Some groups of houses around here that are more or less identically built but on sloped terrain are reported to have widly differing heights
- My neighbour building is reported to be half the height of this building (they're more or less equally high at 5 stories)
- A small office shack behind the neighbour building is reported to be taller than it (it's a single-story building, the neighbour building is 5 stories)
- The freestanding buildings on the farm where I grew up are like you said, badly combined, much of the estimation there seems to be dependent on shadows,etc.

#45The height measure when you click on a building is not very accurate. Clicked on two next to each other (one single floor and one with two floors) and the single story house was marked taller by the site.

#46Google recently has made efforts to link Gemini to Google Earth data. “Earth AI” https://ai.google/earth-ai/ Has anyone tried this? I’m not quite sure how to prompt it effectively.

#47> This is a huge leap from the previous global dataset, which contained about 1.7 billion buildings
I use the monthly release of Overture Maps building dataset and the last one had around 2.3 billion buildings iirc

Yeah some areas I looked at seemed fine (US, EU, Shangahi), but some the buildings are on top of the roads, and they look more like Perlin Noise than actual buildings. E.g main parts of Beijing.
OpenStreetMap and such have pretty good building footprints, sometimes enriched with building heights. Maybe that can be used for some correction

#49All of the houses on my block are very weird shapes on this map, it doesn't reflect reality very well
Indeed, my neighborhood doesn't show any buildings at all even though I know all of our houses have been there at least 30 years and were still there when I left this morning.
When you left this morning, sure, but who knows what’s happened in the interim.

Looking around my home area, I found HS football bleachers showing up as buildings and an outdoor basketball court showing up as a building. Looking at the coloring of those features on Google maps, I can see how the mistakes might have been made. But still feels like it needs tuning.
To be fair, I checked my boyhood home in very rural Maine and it was correct for the size and shape of the multiple farm buildings.
