Source: R/otp-surface.R
otp_make_surface.Rd

Requires OTP 1.x and the analyst

Usage

otp_make_surface(
  otpcon = NULL,
  fromPlace = c(-1.17502, 50.6459),
  mode = "CAR",
  date_time = Sys.time(),
  maxWalkDistance = 1000,
  arriveBy = FALSE,
  routeOptions = NULL,
  timezone = otpcon$timezone,
  ncores = 1
)

Arguments

otpcon

OTP connection object produced by otp_connect()

fromPlace

Numeric vector, Longitude/Latitude pair, e.g. `c(-0.134649,51.529258)`, or 2 column matrix of Longitude/Latitude pairs, or sf data frame of POINTS with CRS 4326

mode

date_time

maxWalkDistance

Numeric passed to OTP in metres

arriveBy

Logical, Whether the trip should depart or arrive at the specified date and time, default FALSE

routeOptions

Named list of values passed to OTP use

timezone

Character, what timezone to use, see as.POSIXct, default is local timezone

ncores

How many cores to use default = 1

Value

Returns a list with information about the surface created

Details

THis function requires the analysis and pointset features to be enabled during `otp_setup()`. Thus it will only work with OTP 1.x. For more detail see the analyst vignette.
