- Entur, Norway
- 2022-05-09 Initial implementation
The API produces a snapshot of travel time form a single place to places around it. The results can be fetched either as a set of isochrones or a raster map.
The feature must be enabled in otp-config.json as follows:
locationOrigin of the search, can be either
latitude,longitudeor a stop id
timeDeparture time as a ISO-8601 time and date (example
2023-04-24T15:40:12+02:00). The default value is the current time.
cutoffThe maximum travel duration as a ISO-8601 duration. The
PTcan be dropped to simplify the value. This parameter can be given multiple times to include multiple isochrones in a single request. The default value is one hour.
modesA list of travel modes. WALK is not implemented, use
falsewhen searching from the location and
truewhen searching to the location
Results is the travel time boundaries at the
cutoff travel time.
Travel time surface API
The travel time as a GeoTIFF raster file. The file has a single 32-bit int band, which contains the travel time in seconds.
