Method
Sun position computed with the SunCalc algorithm (J. Meeus’s formulas), accurate to about one minute for sunrise and sunset times. Sunrise and sunset refer to the upper edge of the sun on a clear, sea-level horizon, including atmospheric refraction: hills or buildings hide the sun earlier. The 3D map also computes the actual sunrise behind the terrain. More about the method.
