Bing uses similar treatment on their satellite imagery and OSM mappers (who are permitted to use it) have been complaining it looks more like painting than actual imagery.
Satellite images have 0.4 m resolution or better these days, what matters most is good color quality (e.g. hyperspherical pansharpening), sensor dynamic range and good lighting conditions (sun elevation in particular).
- razor_router 4y agoWhat kind of technology does Bing use to treat their satellite imagery?
- shiftpgdn 4y ago30/50cm per pixel are the maximum allowable by law in the US for "civilians". I'm sure we could do even better if allowed.
- TOMDM 4y agoI'm having trouble finding citations on the specific law, but this website states that the US has capped satellite imagery for civilian use at 0.31 m https://pubs.acs.org/doi/10.1021/acs.est.0c02365 https://pubs.acs.org/doi/10.1021/acs.est.0c02365

- astrange 4y ago"Satellite" images on maps are often not from satellites but rather planes or drones. I guess with this technique you could do ML image synthesis guided by SAR satellites - that way you could sort-of look through clouds from space, as long as you don't mind the image being largely fictional.
