lixelize_lines.mc: Cut lines into lixels (multicore)

In JeremyGelb/spNetwork: Spatial Analysis on Network

Cut lines into lixels (multicore)

Description

Cut the lines of a feature collection of linestrings into lixels with a specified minimal distance may fail if the line geometries are self intersecting with multicore support.

Usage

lixelize_lines.mc(
  lines,
  lx_length,
  mindist = NULL,
  verbose = TRUE,
  chunk_size = 100
)

Arguments

lines	A feature collection of linestrings to convert to lixels
lx_length	The length of a lixel
mindist	The minimum length of a lixel. After cut, if the length of the final lixel is shorter than the minimum distance, then it is added to the previous lixel. If NULL, then mindist = maxdist/10
verbose	A Boolean indicating if a progress bar must be displayed
chunk_size	The size of a chunk used for multiprocessing. Default is 100.

Value

A feature collection of linestrings

Examples

data(mtl_network)
future::plan(future::multisession(workers=1))
lixels <- lixelize_lines.mc(mtl_network,150,50)
## make sure any open connections are closed afterward
if (!inherits(future::plan(), "sequential")){
future::plan(future::sequential)
}
