Made a visualization to answer my kid's question.
Enter your location (city, town, etc) or drag the red handle to play around.

Made with D3.js on canvas (globe) and SVG (handle).

  1. Per the sub’s rules:
    Source: Formulas – wikipedia, location data api – [geonames.org](http://geonames.org)
    Tools: D3 + Django
    Map: land-110m from https://github.com/topojson/world-atlas

  3. Only thing I would suggest is a way to clarify cities with the same name. Having city and country only forces the user to guess.

  4. Super cool. I love the animation of the globe as you move the needle as well.

  5. mph!? Most people on that globe doesn’t use that. A toggle would be nice

  7. Well, that’s fun!

    I would ask though for a latitude number

  8. It’s pretty trivial to do this in your head. For example, the angular velocity in Paris is 360°/24 h. And the angular velocity of Tokyo is 360°/24 h. See? Easy.

  9. Nice!

    Two things :

    I second the need for a km/h and m/s toggle (the first is used worldwide and the second is the ISO unit for speed)

    Search doesn’t seem to work for me (Tried on chrome and firefox, requests seem to fire but no reaction on UI, and no error on console)

  10. That’s not angular speed. That’s just regular speed

  13. Need to denote states… there’s a billion Portlands and I want the good one. Otherwise sick.

    You need to expand this XKCD style and include solar orbit, solar system orbits around sagg, Milky way blasting off…

  14. looks like you got too many views, city search is broken 🙂

    “the hourly limit of 1000 credits for whileandrey2 has been exceeded. Please throttle your requests or use the commercial service.”

  15. Turns out 1000 searches/hr for free on geonames is not nearly enough for posting your stuff on reddit haha. It updates with another 1000 credits every hour, sorry about that!

  16. The choice to not include major inland bodies of water is… Well it’s certainly a choice.

  17. This is US-centric, but it needs the state in addition to the country. Lots of states have towns with the same name.

  19. Nice job!

    Minor nitpick: You’re showing tangential speed, not angular speed. Angular speed will have units of angles per unit time (e.g. radians per second).

  20. I live at the latitude on the screenshot you posted, so I guess I didn’t even need to open the site. Cool project!

  23. cool

    makes me think that we could switch speed for latitude

    instead of 40º north, 1.275km/h north
