Back in 1983 when Clark Griswold was planning his family’s cross-country roadtrip as depicted in the film, National Lampoon’s Vacation, he was using what we would consider now to be relatively rudimentary navigation software.
These days, digital maps are much more advanced. Mapzen Turn-by-Turn, which is a routing service powered by the Valhalla engine, adds routing and navigation to web or mobile applications. Mapzen’s routing is free and open source, works globally, and provides dynamic and customizable routes for driving, walking, or bicycling, with clear directions for maneuvers along the route.
As you journey through the tutorial, you will build a map that has:
- distances along your route and estimated travel times
- a route line between map locations (also known as waypoints)
- a text narrative of maneuvers to perform on the route
- functionality to drag the route start and endpoints to get a different path
- the ability change the mode of transportation, such as by car or walking
