-Auto Name:Open by Mapzen
-Summary:Map search and navigation using OpenStreetMap
-Description:
-Open (by Mapzen) is a search and navigation app built with open source software
-and open data.
-
-Made with OSM, made for OSM. Users log into the app using an OpenStreetMap
-account. They can optionally contribute GPS traces back to OpenStreetMap when in
-navigation mode.
-
-Really, really open. The app is built with the open source projects
-OpenScienceMap, Open Source Routing Machine (OSRM), Pelias, and open source SDKs
-built by Mapzen.
-
-It’s a map, what do you think it does. Search. Maps. Routes for biking, walking,
-and driving.
-
-Open source, open data, open to improvements. We built Open as a proof of
-concept to understand the current state of open data and open software for
-mapping and navigation. The app and the data will only get better--but only with
-your contributions.
