Radio and communication towers made of wood are rare. Lists of such objects can be found on https://en.wikipedia.org/wiki/Cell_site#Wooden_structures , https://en.wikipedia.org/wiki/List_of_tallest_wooden_buildings_and_structures and https://en.




I don’t normally think about the Sun’s direction when I go out running. When it gets exceptionally hot in summer, I start to notice it and wonder if I can tune my early morning run routes to experience slightly less heat. In principle, that should be possible. The position of the Sun can be worked out with a Python script. Combined with the angle of the Sun in the sky and your heading, it will tell you if you are running straight into the Sun or if the Sun is behind you. My personal preference is running towards the sunrise. After sunrise, you can call OSRM to optimize around solar load, defined as a function of Sun azimuth, your heading, and Sun altitude. This is probably over-engineering for route planning, though. The solar load has no simple formula, and the effect of clouds or humidity is hard to account for. Just a basic knowledge of civil dawn, sunrise time, and sunrise direction is probably enough for everyday running. But back to route generation — if you can find a metric to optimize for, you can generate new routes you have not run before. It is hard to define route novelty, but something like sun direction is easier to work with. The end goal would be to create routes that are different from what you can discover by simply using your street sense.










Seit den ersten Schritten meiner OSM‑Reise liebte ich die Idee von Spielplatzkarten. Dafür gibt es mehrere Gründe, auf die ich hier nicht ausführlich eingehen möchte: offene Daten, Karten, FOSS – und natürlich die Kinder und ihre Freude (und … alle E…


From the very beginning of my OSM journey, I loved the idea of playground maps.
There are several reasons for this, but I won’t go into detail here.
