- macintux 11mo agoI haven't visited the map, but I wouldn't be surprised to learn they didn't attempt to re-create the building shapes, just location and estimated size. The real shape seems pointless for this dataset.
- wongarsu 11mo agoBuilding shapes are actually pretty accurate in urban areas. I haven't read the paper, but I think what they were after is building volume. Which obviously requires the footprint shape and height
- oersted 11mo agoIf it was able to detect roughly how many buildings there are in that area, that’s already fairly useful at global scale. It seems they are focused on measuring urbanization. It’s good to know though that it may be dodgy at that level of granularity.
- freedomben 11mo agoIndeed, 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.
- dhosek 11mo agoWhen you left this morning, sure, but who knows what’s happened in the interim.
