    • Feature request: Global Sun Elevation Isolines

      The layer of Sun Elevation Isolines would help to interpret current temperatures in relation to the position of the sun in the sky.
      In the link below I provide a picture with the example:

      Thanks for your attention.

      @idefix37
      There are some examples of real-time maps:
      https://www.timeanddate.com/worldclock/sunearth.html?iso=20180706T1620
      or
      http://www.spacew.com/www/zenith.html

      But I don't know what algorithms they use for drawing those contours.
      I would use the Sun Position Algorithm and A General Algorithm For The Construction Of Contour Plots developed By NASA.
      1.https://rredc.nrel.gov/solar/codesandalgorithms/spa/
      2. http://www.pdas.com/conplot.html
      Could be that some coordinate transformation applies to the result of the SPA algorithm before feeding it to the contour plotting.

      Ciao guys

      One more thing.
      The equations in the SPA algorithm are of trigonometric nature, therefore it shouldn't be that hard to solve them when Elev.Angle=Const. Thus you get a contour function.Then after applying a coordinate transformation you end up with a compact mathematical function which subsequently can be expressed in the Javascript language.

    • RE: Time Zones visualization

      Oh, Thanks, that solves the issue.
      In addition, it would be nice to see details on the position of the sun at the spot. Like Zenith(or Elevation) and Azimuth. You may also wish to consider some kind of graphical representation for the azimuth angle.
      The algorithm for approximating the position of the Sun could be found in the link below:

    • Time Zones visualization

      Hi. It would be so much helpful to see the time zone lines and numbers indicating time offset relatively to the local time of an app user. For example
      ... -5 -4 -3 -2 -1 0 +1 +2 +3 +4 ...
      Another option is to show current time within each time zone approximating only to hours.

      Awesome job guys, Thanks a lot.
