Creates a line feature and gets the value of their zone of influence on locations over the feature

Description

The function create_linear_feature_zoi() computes the cumulative zone of influence (ZOI) of one single linear feature so it is used to correctly create predictions and response plots for linear infrastructure, considering the potential responses at multiple radii.

Usage

create_linear_feature_zoi(
  radii = c(100, 250, 500, 1000, 2500, 5000, 10000),
  type = c("circle", "Gauss", "rectangle", "exp_decay", "bartlett", "threshold",
    "mfilter")[1],
  radius_max = max(radii),
  zoi_limit = 0.05,
  type_feature_recompute = FALSE,
  res = 100,
  value = 1
)

Arguments

radii	⁠[numeric,vector=c(100, 250, 500, 1000, 2500, 5000, 10000)]⁠ Vector of radii for which the zone of influence should be computed.
type	⁠[character="circle"]{"circle", "Gauss", "rectangle", "exp_decay", "bartlett", "threshold"}⁠ Shape of the zone of influence (ZOI), Default is ⁠circle"⁠. It can assume any of the possible values for the argument type in the function dist_decay().
radius_max	⁠[numeric=max(radii)]⁠ Maximum radius, used to set the size of the landscape/raster for ZOI computations.
res	⁠[numeric(1)=100]⁠ Resolution for the raster created. This might impact what are the values observed in the ZOI.
line_value	⁠[numeric(1)=1]⁠ Value set to the raster line created. Default is 1. It could be changed to different values if we want to represent e.g. the value in the linear feature as the roads traffic or another value for spatio-temporally dynamic variables.

Details

This function could be extended to the nearest ZOI, if needed.
