How do I read the 'AllTrails' map layer?

Each member of our community has slightly different needs in a map. We meet these needs by offering a choice of map layers across our website and apps. When building AllTrails, we realized that no one map option was ideally suited for the outdoor adventurer. In response, we saw the need to create an ideal trail map for the digital age. This is the 'AllTrails' map layer.

One of our main tasks was to determine what kinds of information should be included on the map. What zoom levels do details appear? What are the best sources for data? In the end, the map data itself came from combining a number of trusted sources including OpenStreepMap, USGS, Mapbox, and our own data. The starting point in the visual design was the classic USGS-style topographic map. From there, we wanted to make sure trails were given particular prominence and wanted to include mileage labels on each trail segment (as are often seen on paper trail guide maps). We also wanted to show boundaries for parks and wilderness areas as well as useful points of interest.

LEGEND:

• Trails on the 'AllTrails' map layer are represented as black single dashed lines
• Blue dashed lines mean that bikes are permitted for trails 
• Red squares represent trail intersection markers with the trail distance shown for each major segment
• The new icons below represent the location of points-of-interest that might be useful while out on the trail

NOTE: Points-of-interest icons are not interactive.
