sample_points: Sample Points from a region

In tabrasel/WetlandTools: General utility functions for TerrainWorks

Sample Points from a region

Description

Generates a SpatVector of points in a given area.

Usage

sample_points(count, region, buffer = TRUE, radius = 15, rseed = NULL)

Arguments

count	The number of points to sample
region	A SpatRaster with NA cells anywhere a sampled point cannot be located
buffer	Should points be returned with a buffer?
radius	The radius of each buffer (ignored if buffer = FALSE)
rseed	Optional integer to seed the random sampling. This allows exact "random" results to be reproduced multiple times. If no number is given, a random number will be chosen as a seed.

Details

This extends terra::spatSample() to generate the correct number of sampled points when the sample raster has a lot of NAs.

Value

A SpatVector of buffers.
