The main Trail Survey took place during the years of 1997-2000. Differentially corrected GPS (Global Positioning System) data were collected primarily
on foot for all existing maintained trails and spur trails to backcountry campsites, attractions and buildings within the boundaries of Yellowstone National Park (YNP).The trails that could not be obtained through the GPS or have been rerouted since the survey were acquired through the uses of 1 meter Digital Orthophoto Quarter Quads (DOQQs) and the help of backcountry rangers with knowledge of where the trails are located. There are also associated GPS data for trail bridges, backcountry campsites, patrol cabins and trail surface type. Trail usage data also documented by using visitor ski and bike trail maps. Trails data have been updated since the original survey using information from the Yellowstone Backcountry Office, trails maintenance personnel, best available imagery resources, and GPS data. This layer is a work in progress.
This survey is intended to provide an accurate
geographical coverage of trails within Yellowstone
National Park for the purposes of maintenance and
increased recreational enjoyment.

Data attributes were recorded on-site, during the
GPS survey. Backcountry rangers from each ranger
district also checked the attribute and location
accuracy.
All arcs have complete topology. All overshoots or
undershoots have been corrected and all
unnecessary dangles corrected. The BUILD function
in Arc/Info was evoked on 20000809.
There are several trail segments within the
Yellowstone National Park trail system which have
not been surveyed as of August 2000. The areas
that have not been checked by a backcountry ranger
are the Gallatin and Tower subdistrict. The trails
that are still missing from the coverage are Lost
Creek Falls, Slough Creek Fishing Access, Fern
Cascade, Howard Eaton trail (in old Faithful),
Kepler Cascade, segment of South Boundary from
Harebell Cabin, segment of Howard Eaton from
Artist Point to Sour Creek, Spring Creek Ski Trail
and segment of Yellowstone River.
As of 20050804 Bike and Ski trails that need to be GPSed: Mammoth Area-Ski: Sheepeater Trail; Bighorn Loop; Indian Creek Loop. Bike: Abandon railroad bed paralleling the Yellowstone River between Gardiner and the park boundary at Reese Creek (5mi). Cayon Area- Ski: ~1.5 mi in on the Cascade Lake Trail; Roller Coaster Trail; Portion of Canyon Rim Trail that dosent't follow road. Tower/Lamar Area-Ski: Lost Lake Trail all the way up to Blacktail Plateau Trail; Cutoff to parking area on Blacktail Plateau Trail. Bike: Rose Creek Service Road behing Yellowstone Institute (crosses creek
follows stream up to spring).
The data produced from GPS field data are assumed
to be spatially accurate to within 2-5 meters.
Maximum PDOP was set to 6 and data were only
collected when at least 4 satellites were
readable. Data acquired from DOQQs can have a
spatial accuracy within 5-10 meters.

GPS data were collected with Trimble ProXR, PROXL
& ProXRS by volunteers on foot during the summer
field seasons of 1997, 1998, and 1999.
Multiple dates (see above)
GPS files were differentially corrected using base
station data from the Idaho Fall, Idaho GPS
Community Base Station at INEL.The GPS processing
software was Trimble Pathfinder Office Versions
2.11 through 2.5.
Multiple dates (see above)
Data were brought into Arc/Info v7.1. & 8.01 The
node errors were eliminated from the coverage by
snapping all intersecting arcs together. Arcs
representing trails were also snapped to their
corresponding bridges and campsites.
20000301
Features were quality controlled by verifying the
locations of the features with the NPS district
rangers. Backcountry trails locations that were
not surveyed with a GPS or rerouted with in the
three year survey period were obtained by having
backcountry rangers from each district identify
where the trail is located on a 1-meter DOQQ.
Using ArcView, a line was digitized to the
specified location. The ArcView shapefile of
trails was converted to an Arc/Info coverage using
the SHAPEARC command with PRECISION set to DOUBLE
HIGH. The coverage was then added to the coverage
containing the GPS trails using the PUT command
in ArcEdit.

SURVYDAT:date the feature was surveyed; NAME:
common trail name. The NAME of the Trail were
obtained using Trails Illustrated Map and the

Spur trail, an off shoot of the main trail that
either goes to a backcountry campsite, attraction
or building, a Boardwalk or Paved Path; SURVEY;

The main Trail Survey took place during the years of 1997-2000. Differentially corrected GPS (Global Positioning System) data were collected primarily on foot for all existing maintained trails and spur trails to backcountry campsites, attractions and buildings within the boundaries of Yellowstone National Park (YNP).The trails that could not be obtained through the GPS or have been rerouted since the survey were acquired through the uses of 1 meter Digital Orthophoto Quarter Quads (DOQQs) and the help of backcountry rangers with knowledge of where the trails are located. There are also associated GPS data for trail bridges, backcountry campsites, patrol cabins and trail surface type. Trail usage data also documented by using visitor ski and bike trail maps. Trails data have been updated since the original survey using information from the Yellowstone Backcountry Office, trails maintenance personnel, best available imagery resources, and GPS data. This layer is a work in progress.
Data were brought into Arc/Info v7.1. & 8.01 The node errors were eliminated from the coverage by snapping all intersecting arcs together. Arcs representing trails were also snapped to their corresponding bridges and campsites.

Features were quality controlled by verifying the locations of the features with the NPS district rangers. Backcountry trails locations that were not surveyed with a GPS or rerouted with in the three year survey period were obtained by having backcountry rangers from each district identify where the trail is located on a 1-meter DOQQ. Using ArcView, a line was digitized to the specified location. The ArcView shapefile of trails was converted to an Arc/Info coverage using the SHAPEARC command with PRECISION set to DOUBLE HIGH. The coverage was then added to the coverage containing the GPS trails using the PUT command in ArcEdit.

2005 trails survey conducted by adding new attribute field, called USAGE. Various maps of area ski trails and bike trails were obtained from the visitor center. These maps were used to populate trail USAGE attribute.

Updated trails layer per meeting with Chris Glenn, Ivan Kowski, and others. Received 24k base maps with edits included.
2008-08-01
Edited trails to conform more closely to NPS Enterprise Data standard. Added fields and populated. Still much more work to be done on this layer.
2009-04-01
FMSS Location ID's added to trail segments.
2010-01-01
FMSS database
Added the following fields: Trail_Type, Surface, Use_Stock, Use_Foot, Use_Bike, Use_Ski, and Use_Service Road. The new "Surface" field replaces the old, confusing one. The "Use_" fields were added to clarify the "Usage" field.
