Make an isochrone from a surface

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

Make a raster image (picture) of travel time using the surface features in OTP 1.x

Usage

otp_surface_isochrone(otpcon = NULL, surface = NULL)

Arguments

otpcon

OTP connection object produced by otp_connect()

surface

A surface list from otp_make_surface()

Value

Returns a data.frame of travel times

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.

Examples

if (FALSE) { # \dontrun{
times <- otp_surface(otpcon, c(-1.17502, 50.64590), "lsoa", path_data)
} # }
