rnd_locations {spaths}

Random location drawing

Description

This function draws random unprojected (lonlat) locations.

Usage

rnd_locations(
  nobs,
  xmin = -180,
  xmax = 180,
  ymin = -90,
  ymax = 90,
  output_type = c("data.table", "data.frame", "SpatVector")
)

Arguments

nobs

Number of observations

xmin

Minimum longitude

xmax

Maximum longitude

ymin

Minimum latitude

ymax

Maximum latitude

output_type

type of output object. Either "data.table" (default), "data.frame", or "SpatVector".

Details

By default, the function draws a global sample of random locations. You can restrict it to a certain region via specifying xmin, xmax, ymin, and ymax. The function draws from a uniform spatial distribution that assumes the planet to be a perfect sphere. The spherical assumption is common in GIS functions, but deviates from Earth's exact shape.

Value

Returns a data.table, data.frame, or SpatVector object of unprojected (lonlat) points.

Examples

rnd_locations(1000)
