Distance Matrix (Time Filter)

Given origin and destination points filter out points that cannot be reached within specified time limit. Find out travel times, distances and costs between an origin and up to 2,000 destination points.

Learn more about our distance matrix service

Making a distance matrix

To create a matrix of distances between many locations you will need to use multiple arrival and destination searches.

For example given three points A, B, C you would need three arrival searches - one for each point.

• A -> { B, C }
• B -> { A, C }
• C -> { A, B }
  

For modes other than walking and cycling this needs to be repeated for departure searches (swapping the arrival_location_id into departure_location_id and departure_location_ids into arrival_location_ids).

Use Cases

Office Relocation

Your company wants to relocate. You have coordinates of potential new office locations and coordinates of your employees’ homes. You want your employees to be at work at 9am, you can use time-filter to find the office that most of your employees will be able to reach within a certain period of time using public transport.
