Get the Isochrones from a location
otp_isochrone( otpcon = NA, fromPlace = NA, fromID = NULL, mode = "TRANSIT", date_time = Sys.time(), arriveBy = FALSE, maxWalkDistance = 1000, routingOptions = NULL, cutoffSec = c(600, 1200, 1800, 2400, 3000, 3600), ncores = 1, timezone = otpcon$timezone )
OTP connection object produced by otp_connect()
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
character vector same length as fromPlace
character vector of one or more modes of travel valid values TRANSIT, WALK, BICYCLE, CAR, BUS, RAIL, default CAR. Not all combinations are valid e.g. c("WALK","BUS") is valid but c("WALK","CAR") is not.
POSIXct, a date and time, defaults to current date and time
Logical, Whether the trip should depart or arrive at the specified date and time, default FALSE
maximum distance to walk in metres
named list passed to OTP see `otp_routing_options()`
Numeric vector, number of seconds to define the break points of each Isochrone
number of cores to use in parallel processing
character, timezone to use, default from otpcon
Returns a SF data.frame of POLYGONs
Isochrones are maps of equal travel time, for a given location a map is produced showing how long it takes to reach each location.
Isochrones are only available from OTP v1.x and will not work with v2.0
