although cameras can pick up what light pollution (aka we) stole from us, viewing the aurora without light pollution during a solar storm this intense is an experience i truly want everyone to have.
These aren't clouds overhead in Minneapolis tonight
I wish cities would turn the lights off when the aurora is visible
i don't want to name names, but there's a big, widely used road dataset that just assigns a "yes" to a sidewalk attribute if the road segment is not a freeway. so there's a ton of roads with 30+mph posted speed limits and no sidewalks, that appears "walkable" when used in these kinds of analyses.
one major issue plaguing our ability to map the 15 minute city concept effectively: data on pedestrian infrastructure (sidewalks, trails, etc.) in the US is wildly inconsistent, if not downright bad.
imo, the CityAccessMap is better than the SonyCSL map. Input data might differ slightly, but the results are pretty consistent and it uses heat maps instead of clustering.
berlin has a lot more dark blue, and the dark blue is more continuous, indicating better/faster access to resources and services. 15 minutes--3/4 of a mile--is a pretty large radius in most gridded American cities.
scale issues aside, these maps do not show the same thing. the map of seattle shows clustered areas that meet 15 minute city critieria. the berlin map shows that the entire city (more or less) meets it. the only part of seattle that's comparable to all of berlin is downtown.
