simulateLandscape-constructor-class: SimulateLandscape Method

In SEHmodel: Spatial Exposure-Hazard Model for Exposure and Impact Assessment on Exposed Individuals

Description

Create an object Landscape. 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

An S4 Landscape object with n fields, prop pourcentage of toxic fields.
