Icon Attribute Unit Range Description Default value
SUN_ALTITUDE angle (0-90°) The sun angle up from the horizon. 49.71

Notes

  • The sun altitude and azimuth are (re)calculated automatically based on the project world location and the date, when the dates of the overlay are modified via the Heat Overlay configuration wizard. They are not automatically recalculated when the dates attribute of the Heat Overlay is modified directly.
