genRandomPntsByGrd: Generate random points based on distance constraints

In raff-k/Lslide: Functions for object-oriented image analysis in landslide science

Generate random points based on distance constraints

Description

This function generate random points inside polygons based on distance constraints. The function is based on spatstat::rSSI.

Usage

genRandomPntsByGrd(x, r, field, env.grass, do.PointsOnSurface = TRUE,
  dist, save.path = NULL, quiet = TRUE, seed = 12345)

Arguments

x	object of class sf
r	rsater layer object
field	field of x object for rasterisation
env.grass	setting for GRASS GIS initiation
do.PointsOnSurface	if TRUE than points on surface are generated for missed objects. Default: TRUE
dist	minimum distance between points
save.path	full path to store the result. Default: NULL
quiet	no outputs in console. Default: TRUE
seed	number to determine the randomness. Default: 12345
...	additional parameters for spatstat::rSSI-function

Value

Randomly sampled points of class sf
