Hikable.com just launched, giving hikers step by step trail descriptions and tools for planing trips on detailed terrain map with elevation data. Anyone can now create their own hiking guides on a map that shows every mountain, river, stream, and summit using Mapbox Outdoors - the map also is updating trails, walkways, and street in real time from OpenStreetMap.
Mapbox Outdoors is available for Enterprise plan holders now and will be available this summer for all Mapbox plans. Let us know if you want early access.
