wbt_time_in_daylight: Time in daylight

Description

Calculates the proportion of time a location is not within an area of shadow.

Usage

wbt_time_in_daylight(
  dem,
  output,
  lat,
  long,
  az_fraction = 10,
  max_dist = 100,
  utc_offset = "00:00",
  start_day = 1,
  end_day = 365,
  start_time = "00:00:00",
  end_time = "23:59:59",
  wd = NULL,
  verbose_mode = NULL,
  compress_rasters = NULL,
  command_only = FALSE
)

Value

Returns the tool text outputs.

Arguments

dem: Input raster DEM file.
output: Output raster file.
lat: Centre point latitude.
long: Centre point longitude.
az_fraction: Azimuth fraction in degrees.
max_dist: Optional maximum search distance. Minimum value is 5 x cell size.
utc_offset: UTC time offset, in hours (e.g. -04:00, +06:00).
start_day: Start day of the year (1-365).
end_day: End day of the year (1-365).
start_time: Starting hour to track shadows (e.g. 5, 5:00, 05:00:00). Assumes 24-hour time: HH:MM:SS. 'sunrise' is also a valid time.
end_time: Ending hour to track shadows (e.g. 21, 21:00, 21:00:00). Assumes 24-hour time: HH:MM:SS. 'sunset' is also a valid time.
wd: Changes the working directory. Default: NULL will use the value in WhiteboxTools settings, see wbt_wd() for details.
verbose_mode: Sets verbose mode. If verbose mode is FALSE, tools will not print output messages. Default: NULL will use the value in WhiteboxTools settings, see wbt_verbose() for details.
compress_rasters: Sets the flag used by 'WhiteboxTools' to determine whether to use compression for output rasters. Default: NULL will use the value in WhiteboxTools settings, see wbt_compress_rasters() for details.
command_only: Return command that would be executed by system() rather than running tool. Default: FALSE.
