Landscape photographers typically wish to plan their shoots around the times of sunrise/sunset or twilight, or alternatively when the moon is in a particular place in a particular phase.
While times of sunrise etc. are readily available on various sites on the internet (direction of sunrise etc. less so, but still readily found), there are fewer programs available which combine such information with a topographical map allowing the photographer to match the astronomical to the location.
A typical use might be to determine when the sun will set along the axis of a mountain valley, or when a full moon rise will rise across a lake.
The application uses Google Maps providing users the ability to select a location and determine the time and azimuth of sunrise or sunset for a given date or dates
