أدخل ارتفاع سطح النقطية.
Output global radiation raster
The output raster representing the global radiation or total amount of
incoming solar insolation (direct + diffuse) calculated for each location of
the input surface.
The output has units of watt hours per square meter (WH/m2).
Latitude (optional)
The latitude for the site area. The units are decimal degrees, with
positive values for the northern hemisphere and negative for the southern.
For input surface rasters containing a spatial reference, the mean latitude
is automatically calculated; otherwise, latitude will default to 45 degrees.
Sky size / Resolution (optional)
The resolution or sky size for the viewshed, sky map, and sun map rasters.
The units are cells.
The default creates a raster of 200 by 200 cells.
Time configuration (optional)
Specifies the time period to use for the calculations.
· Special days—Calculates solar insolation for the solstice days (summer and
winter) and the equinox days (where the insolation for both spring and fall
equinox are the same).
· Within a day—Performs calculations for a specified time period within one
single day.
Select the Julian Day and enter the
start and end times. When the start time and the end time are the same,
instantaneous insolation will be calculated. When the start time is before
sunrise and the end time is after sunset, insolation will be calculated for the
whole day.
o To facilitate entering the correct day, use the calendar button to open
the Calendar dialog box.
o To set start and end times, use the clock button to open the Time
Conversion dialog box. Here you can enter the local solar time, or the local
standard time, while correcting for your degree of longitude and time zone.
· Multiple days in a year—Performs calculations for a specific multiple-day
period within a year.
Specify the start year, start day, and
end day. When the end day is smaller than the start day, the end day is
considered to be in the following year. The default time configuration starts

o To facilitate entering the correct days, use the calendar button to open
the Calendar dialog box.
