I've been wondering about using OpenStreetMap data to achieve something similar, like getting the longest uninterrupted (by buildings) distance between two viewpoints (the Nikon Coolpix P900/P1000/P1100 cameras or a telescope are pretty good for this due to their extreme focal lengths), or maybe something like "most ice cream shop dense area" https://wiki.openstreetmap.org/wiki/Key:amenity https://wiki.openstreetmap.org/wiki/Key:amenity Putting the typical airplane cruise altitude (10km) into the distance to horizon calculator https://www.ringbell.co.uk/info/hdist.htm https://www.ringbell.co.uk/info/hdist.htm results in a "reverse" distance of 357km to the horizon. So that's how far typical airplanes can be seen when standing at sea level!

The answer to the ice cream question (for places where ice cream can be bought) appears to be Buenos Aires! https://overpass-turbo.eu/?Q=%5Bout%3Ajson%5D%3B%0Anode%28%7B%7Bbbox%7D%7D%29%5B%22amenity%22%3D%22ice_cream%22%5D%3B%0Aout%20body%3B%0A&C=-34.639705%3B-58.416417%3B12&R= https://overpass-turbo.eu/?Q=%5Bout%3Ajson%5D%3B%0Anode%28%7...
