How do I read the 'AllTrails' map layer?

Our community of outdoor enthusiasts each have slightly different needs in a map. We have tried to meet these needs by offering a choice of map layers across our website and apps. In both using these maps ourselves and in hearing feedback from our members, we realized that while each has its strengths, no one map option was ideally suited for the outdoors. We saw the need to create an ideal trail map for the digital age through our AllTrails map layer.  

One of our main tasks was to determine what kinds of information should be included on the map, at what zoom levels these details should appear, and what are the best data sources. 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 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.
