Visibility Graph Analysis - isovist metrics

Description

Runs axial analysis to get the local metrics Control and Controllability

Usage

vgaIsovist(pointMap, boundaryMap, copyMap = TRUE)

Arguments

pointMap	A PointMap
boundaryMap	A ShapeMap of lines
copyMap	Optional. Copy the internal sala map

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
  )
boundaryMap <- as(sfMap[, c()], "ShapeMap")
vgaIsovist(pointMap, boundaryMap)
