Day and Night World Map
Seeing the visual representation of the time of day in various places in the world could be a very useful aid in business, tourism, and other areas. This demo shows you how to implement the day/night view with amCharts Maps.
Key implementation details
The sun is just a circle bullet on a
MapPointSeries that we position using the open source calculation functions available here. The “night” is just 3 overlayed “geo circles” (circles defined by geographic coordinates with radius in degrees). We use 3 circles with different radii to create the transitional twilight area. The center of the circles is position on the exactly opposed side of the world to the sun position.
