JuicyTrails is built using OpenStreetMap data. Anyone can "Improve" the map by mapping trails using our OpenStreetMap iD editor customized for JuicyTrails. This map editor contains everything needed for rapidly mapping trails. Click "Improve this map" in the bottom right-hand corner of the JuicyTrails map to open the editor.
Here is the cheatsheet we use for tagging trails in OpenStreetMap.
- Map a Path
A path "...is a generic path, either multi-use or unspecified usage, open to all non-motorized vehicles. The path may have any type of surface." In the JuicyTrails map, paths are colored as thin red lines. To map a path first map a way and apply the tag highway=path. In general, if trail is a multi-use trail (e.g. hiking, horse, and bicycle) it is better to tag it as a path then designate each of the permitted uses, because the tags highway=footway, highway=bridleway, and highway=cycleway are meant to imply exclusion of other types of travel, though the degree of exclusivity varies by country. The tag highway=footway usually implies an urban, paved pathway. Furthermore, in the USA, it is nearly invariably true that all trails permit hiking. Therefore, it is arguably the case any dirt trails in the USA not permitting motorized vehicles should be tagged highway=path, followed by tags designating each of the permitted uses. We find doing so simplifies trail mapping.
- Map a Hiking Trail
A hiking trail is a dirt path used exclusively by pedestrians. In the JuicyTrails map hiking trails are colored magenta. To map a hiking trail first map a way and then apply the tag highway=path. Then then apply a surface tag such as surface=ground to designate the path as a trail, because paths can refer to either paved or unpaved ways.
Note that footways generally refer to urban, paved pedestrian ways, so we prefer the highway=path tag for mapping hiking trails. However, if you choose to use highway=footway, and the footway is a trail, be sure to add a surface tag like surface=ground to indicate that the trail is unpaved, and it will be rendered as a magenta hiking trail in the JuicyTrails map.
- Map a Hiking and Horse Trail
In the JuicyTrails map hiking and horse trails are colored purple. In the USA it is nearly invariably true that if horses are allowed on a trail, hiking is also allowed, making it a multi-use trail. Therefore, to create a hiking and horse trail we recommend first to map a way then apply the tag highway=path, then designate that horses are foot traffic are permitted by applying the horse=yes and foot=yes tags. But note that a hiking and horse trail will be rendered purple in the JuicyTrails map even if the foot=yes tag is not applied. The surface tag is not required, but useful if known.
In other countries, bridleways, where only horses are permitted, are more common. If you choose to use the bridleway tag and the trail is not paved, be sure to apply a surface tag like surface=ground so that the bridleway will render as a purple hiking and horse trail in the JuicyTrails map. But note that all bridleways are colored dark purple in the JuicyTrails map irrespective of whether a surface tag is or is not applied.
- Map a Hiking and Biking Trail
In the USA it nearly invariably true that if bicycles are allowed on a trail, hiking is also allowed, making it a multi-use trail. Therefore, to create a hiking and biking trail we recommend first to map a way then apply the tag highway=path, then designate that foot travel is permitted by applying the foot=yes tag, and bicycles are permitted by applying the bicycle=yes tag. But note that for the JuicyTrails map, if a path is tagged as bicycle=yes, the trail will be rendered as an orange line even if the foot=yes tag has not been applied. The surface tag is not required, but useful if known.
A cycleway indicates a separate way used by cyclists and implies restrictions to other kinds of access. If you chose to map a trail as a cycleway, be sure to apply a surface tag like surface=ground to show that the cycleway is a trail and not a paved path, and if foot traffic is permitted, also apply the foot=yes tag. A cycleway tagged with a surface tag like surface=ground will be rendered as an orange line regardless of whether the foot=yes tag is applied.
- Map a Hiking, Horse, and Biking Trail
Hiking, horse, and biking multi-use trails are colored dark orange in the JuicyTrails map. To create a hiking, horse and biking trail we recommend first to map a way then apply the tag highway=path, then designate that foot, horses, and bicycles travel are permitted by applying the foot=yes, horse=yes, and bicycle=yes tags. The surface tag is not required, but useful if known. But note that since hiking use is implied by horse and bicycle use, the JuicyTrails map will color a hiking, horse, and bicycle trail as dark orange even if the foot=yes tag is not applied.
We do not recommend using highway=footway, highway=bridleway, or highway=cycleway tags to generate hiking, horse, and biking trails because these tags are meant to imply exclusion from other types of trail activities though the degree of exclusion varies by country. Therefore, we think the highway=path tag is most appropriate because by default it implies that it is open to non-motorized forms of travel.
- Map a Motorcycle Trail
In the JuicyTrails map motorcycle trails are colored dark green. Since the OpenStreetMap wiki does not provide clear guidance on how to tag motorcycle trails, and since it is generally true that motorcycle trails are multi-use singletrack trails where hiking, biking, and even horseback riding is often permitted, we recommend creating them like other trails. To create a motorcycle trail we recommend first to map a way, and then apply the tag highway=path, then apply the motorcycle=yes tag. If other uses are permitted, then apply the other designations (e.g. foot=yes, horse=yes, bicycle=yes). But note that for the JuicyTrails map, tagging a path as motorcycle=yes will render the trail as a green line irrespective of whether or not other tags are applied. The surface tag is not required, but useful if known.
- Map an ATV trail
In the JuicyTrails map, ATV trails are colored olive drab green. The tag atv=yes "...is to be used where there are restrictions on the way limiting the width of the vehicle to 50 inches (50"/1.27m) or less. In the US, these vehicles are called "ATV," "Quad" or "4 wheeler". The use of atv=* implies motorcycle=yes". ATV use permitted on full-size vehicle tracks should be tagged highway=track and then atv=yes (but not that the JuicyTrails map renders these as brown track lines rather than olive drab green paths). However, ATV trails permitted on trails where full-size vehicles can't travel (e.g. width equal to or less than 50 inches) should be tagged as highway=path then atv=yes, especially in the case of multi-use trails where other forms of non-motorized travel are legally signed. For example, it is quite common for 50 inch wide ATV trails that do not permit full-size vehicles to permit hiking, bicycles, motorcycles, and even horses (e.g. ATV trails in USA National Forests). In such cases tag the ATV trail as highway=path, foot=yes, horse=yes, and bicycle=yes. But note that for the JuicyTrails the highway=path and atv=yes are the only way to render a trail olive drab green, and this works irrespective of whether other tags are applied. Applying a surface tag like surface=ground is not required, but helpful if known.
