calc_odm (single core)

Source: R/calc_odm.R

Looped calculation of duration and distance matrices between all sources and targets (single core)

calc_odm(profile_string, source_locations, target_locations, max_chunk_size)

Arguments

profile_string

Route profile
source_locations

sf object of geometry type point containing the sources with coordinates in separate x, y columns
target_locations

data.frame containing the targets with coordinates in separate x, y columns
max_chunk_size

integer value defining the maximum number of source to target connections to be processed per loop

Value

odm-object of type list encompassing duration and distance matrices and the source and target locations

Examples

if (FALSE) {
data(testdata)
options(openrouteservice.url = "SERVER URL")
sources <- testdata$od_result$sources
targets <- testdata$od_result$targets
max_chunk_size <- 200 # depends on the config of the OpenRouteService server
res <- calc_odm(
  profile_string = "foot-walking",
  source_locations = sources,
  target_locations = targets,
  max_chunk_size = max_chunk_size
)
