simulateLandscape: Simulate a new landscape

In briskaR: Biological Risk Assessment

Description

Create an object of class SpatialPolygonsDataFrame. Simulate a landscape with neutral and source fields and receptors margins.

Usage

simulateLandscape(
  n = 500,
  prop = 0.4,
  range = 10,
  xmin = 0,
  xmax = 5000,
  ymin = 0,
  ymax = 5000,
  border_size = 200,
  prob = runif(1, 0.1, 0.9),
  mean_thickness = runif(1, 2, 20),
  v_thickness = 50
)

Arguments

n	Numeric, numbers of fields
prop	Numeric [0,1] toxic fields proportion
range	aggregation parameter (range of the spatial exponential covariance of gaussian process) in meters.
xmin	x-axis left coordinates
xmax	x-axis right coordinates
ymin	y-axis bottom coordinates
ymax	y-axis top coordinates
border_size	A numeric, bbox margin
prob	Probability to inflate a filed margin
mean_thickness	Margin width expectation
v_thickness	Margin width variance

Details

Execute both simulateInitialPartition and simulateThickMargins functions.

Value

A SpatialPolygonsDataFrame object with n fields, prop pourcentage of toxic fields.
