In alcyon: Spatial Network Analysis

Visibility Graph Analysis - Visual local metrics

Description

Runs Visibility Graph Analysis to get visual local metrics

Usage

vgaVisualLocal(
  pointMap,
  nthreads = 1L,
  algorithm = VGALocalAlgorithm$Standard,
  copyMap = TRUE,
  gatesOnly = FALSE,
  progress = FALSE
)

Arguments

pointMap	A PointMap
nthreads	Optional. Number of threads to use (defaults to 1)
algorithm	Optional. The algorithm to use. See ?VGALocalAlgorithm
copyMap	Optional. Copy the internal sala map
gatesOnly	Optional. Only keep the values at specific gates
progress	Optional. Enable progress display

Value

A new PointMap with the results included

Examples

mifFile <- system.file(
    "extdata", "testdata", "simple",
    "simple_interior.mif",
    package = "alcyon"
  )
  sfMap <- st_read(mifFile,
    geometry_column = 1L, quiet = TRUE
  )
  pointMap <- makeVGAPointMap(
    sfMap,
    gridSize = 0.5,
    fillX = 3.0,
    fillY = 6.0,
    maxVisibility = NA,
    boundaryGraph = FALSE,
    verbose = FALSE
  )
vgaVisualLocal(pointMap, FALSE)
