Roads and Tracks

Apart from the AZ 64 and many of the roads of the Grand Canyon Village, almost all of the forest service roads and other tracks have been unreviewed since the Tiger import in 2007. Many of the tracks are either mapped incorrectly or don't exist at all. A lot of work to be done here.

Sources of data include


The aim of this project is to map all of the official hiking trails listed in the Wikipedia entry.

Within the Grand Canyon, OSM data is already, I think, superior to other online maps in coverage and accuracy (Google is particularly poor here). There are a number of ways we can enhance the usefulness of OSM to mappers and hikers in the future;


Trails within the canyon itself are closed to bicyles and motorbikes, so the ways representing trails should be tagged;

highway=path should be preferred over highway=footway.

See Hiking for possible tagging of hiking trails.


Ultimately we're aiming to represent all the trails as a set of relations. Currently the following tag schema is used for these relations;

Optional tags can be added for wikipedia or other web entries. See Walking Routes for further ideas on how to tag hiking relations.

Manmade Features

Water sources, emergency telephones, campgrounds, ranger stations, toilets, parking and trailheads. Also the buildings and facilities in the North Rim, Grand Canyon Village and Desert View.

Natural Features

Mountains, rivers, valleys, waterfalls, springs, minor canyons, rock formations and other points of natural interest.


There is currently some discussion in the OSM community about the tagging of dry rivers, but until there's a consensus this project is using the following schema;

Dry creeks, washes, arroyos and other dry stream beds should be tagged;

Though it's a moot point when applied to dry rivers, according to OSM guidelines a river becomes a stream if 'it can be jumped across by an active, able-bodied person', or roughly less than 2 meters in width.

seasonal=no applies to river beds that only flow during rare floods (classed as 'ephemeral' by the USGS). This would apply to the majority of dry creeks in the desert areas of Arizona.

Tiger 2014

The latest Tiger 2014 data has a comprehensive and reasonably accurate set of line data for waterways in Coconino county which can be used as a guide for tracing creeks or imported directly. A few points;

  • Some of the data points are very dense - simplify ways with excessive nodes before uploading into OSM
  • There is naming information in the Tiger data (the FULLNAME tag), but this is incomplete, uses abbreviations (crk instead of creek) and sometimes incorrect. Check and correct all names against other sources, e.g. the USGS Topographic Maps layer in JOSM
  • There are still some errors in the Tiger data - at a minimum all new waterways should be visually checked against Bing imagery before uploading. In particular the direction of water flow is often incorrect.

Wikipedia Integration

To make the map more useful and expose it to a wider audience, any relevant object in the map should be linked to its corresponding Wikipedia article. Just add a wikipedia=* tag to the node, way or relation and reference the relevant wikipedia article - use the URL for the article after the final forward slash. The WIWOSM preferred format is; wikipedia=lang:article

For example, the Bright Angel Trail has a Wikipedia entry with the URL address

and the relevant tag is;
