An overview of time classes

Disponible con una licencia de Spatial Analyst.

Time classes are used to specify the time configuration for calculating solar radiation. There are four types of time classes to specify a period of time within a single day, for multiple days in a year, for special days (solstice and equinox), and for a whole year.

Class	Description
TimeMultipleDays	Defines a multiple day time period within a given year to perform solar calculations. A year, start day, and end day are specified.
TimeSpecialDays	Defines the summer solstice/equinox/winter solstice days as the time period to perform solar calculations.
TimeWholeYear	Defines a year, using monthly intervals, to perform solar calculations.
TimeWithinDay	Defines a time period within one day to perform solar calculations. A Julian Day, start time, and end time are specified.
