PURPOSE

This document is intended to take the complex working draft of the
Inter-Agency Trails Data Standards (ITDS) documents and extract the
actual draft standards into a document that can be used by individual
agencies and groups to implement the standard.

BACKGROUND

The Interagency Definition of a Trail: Defined by the Interagency Trail
Data Standards Team in July 2002. The interagency definition is based on
and encompasses individual agency definitions of a trail, and includes
"standard" trails, National Scenic Trails and National Historic Trails.

**Trail: A linear route managed for human-powered, stock, or Off Highway
Vehicle (OHV) forms of transportation or for historic or heritage
values.**

Trails provide public access for outdoor recreation opportunities as
well as access to many significant prehistoric and historic sites.

Some portions of historic trails are accessible today, and provide
recreational and other benefits, while others, more \'virtual\' in
nature, provide a cultural and/or historic experience, but are not
physically capable of being traversed or accessed. Historic trails can
consist of a path, a route, a corridor, a road, a river/stream, etc.
*(See \"NHT Corridor Concept\" below.)*

*(Refer to individual agency trail definitions for further
agency-specific guidance or direction on defining a trail.)*

UNDERSTANDING NATIONAL HISTORIC TRAILS (NHTs): The Corridor Concept

National Historic Trails differ from \"regular\" trails, which can
generally be described, inventoried and managed as one linear route.
This is not usually the case with NHTs. To better understand the
inventory and management of NHTs, it is helpful to consider each NHT as
an unofficial, informal \"corridor\", rather than a single line on a
map. Each "NHT corridor" is comprised of two and often three aspects:

NHT^1^

Designated Route: What and where is the congressionally designated NHT
route and associated NHT heritage sites? \[NHT^1^ is identified for all
NHTs.\]

NHT^2^

Heritage Resources: What and where is the route and sites where history
actually occurred? \[NHT^2^ occurs on all NHTs, although physical
evidence and/or remnants may no longer be present. Location may be other
than the congressionally designated route.\]

NHT^3^

Recreation and/or Interpretive Trail/Road/Sites: Where/what is the route
and associated sites that people can use (i.e. trail/road/site used for
recreation or interpretation)? \[May or may not be present. NHT^3^
location may vary from the congressionally designated route and/or
original, historically used route.\]

To be effective, NHT administrators and managers rely on data
representing two to three of these various components that can occur
within an NHT corridor. It is important to note that "corridor" is used
here as an unofficial descriptive concept, and is not intended to imply
the existence of actual area boundaries.

IMPLEMENTATION

The ITDS data standard is intended to be implemented where each trail
segment or section has the appropriate attributes assigned to it.
Because the data standard is not a 'how to' for implementation, it has
been left to the individual agencies to determine how the attributes
should be assigned and maintained. Some may choose the dynamic
segmentation option while others may choose to implement transportation
routes. Either way is acceptable as long as the required attributes are
properly connected with the correct geographic trail sections and that
method is documented.

One item of discussion for each agency implementing this standard will
be that there exist certain attribute fields that will not be physically
stored with the trails data on an everyday basis. This data may be
derived via a geospatial or other query, or simply added when the data
is prepared in response to a request for the data. Some of these have
been noted in the documentation of the individual attributes. The final
implementation decisions and database design are at this time incomplete
and should account for this information.

The ITDS team has agreed that the standard will include Federal
Geographic Data Committee (FGDC) Metadata for all geospatial Trails
data. This metadata is not spelled out in the ITDS data standards but
can be located at the following website: http://www.fgdc.gov/. The
correct document number is FGDC-STD-001-1998

It has been noted that in the event of an Agency implementing the ITDS
data standard in the Environmental Systems Research Institute (ESRI)
ArcGIS software suite, the following information should also be included
either in the FGDC metadata or in some other format. The ITDS standards
team has attempted to avoid telling people how to complete their
implementation of the standard. Rather, the team has identified those
items that it believes are important to include in whatever
implementation is completed.

The following table lists some general information about the data
standard which all data collected should meet.

+------------+---------------------------------------------------------+

|            | The method of determining accuracy should be documented |
|            | in the process step of the dataset metadata record. If  |
|            | published accuracy results are used, use the statement  |
|            | 'Compiled to meet \_\_\_ (meters, feet) horizontal      |
|            | accuracy at 95% confidence interval' in the metadata    |
|            | record, and identify the testing source used. If        |
|            | accuracy is locally tested to NSSDA standards, the      |
|            | statement 'Tested to meet \_\_\_ (meters, feet)         |
|            | horizontal accuracy at 95% confidence interval' should  |
|            | be added to the metadata record.                        |
|            |                                                         |

|            | the accuracy standard in place at the time of data      |
|            | collection (typically National Map Accuracy Standards). |

During the development of the data standard, one of the items considered
as a part of the data parameters was the determination of whether the
individual attribute would represent unique values. No Columns/
Attributes listed here would have a unique set of values. Therefore, do
not plan to use any of these attributes as database keys. Primary and
Foreign keys will need to be system generated according to the
implementing agencies' data standards.

The remaining data parameters are defined at the end of the Trails
Attributes Table in the next section.

TRAILS ATTRIBUTES TABLE

The following table shows the trail attributes and their associated
structure. It also shows which attributes are required for which type of
trail. The GIS ITEM NAME field is the formal attribute name and is 10
characters wide. This allows for the use of shapefiles for transfer of
data from one agency to another. The preferred method would be to use a
personal geodatabase layer but that may not always be possible. The GIS
Alternate Name field is the longer version of the name and is commonly
referred to as the alias for the field name. By using an 'alias' field,
we are able to create one that is wider than 10 characters and has more
complete and descriptive names within it.

1\. AGENCY DATA SOURCE

Attribute Definition: Each agency shall identify itself as the source of
the ITDS data for the data it has in its database.

Notes: This attribute is required for all trail types. This attribute
may be stored or simply applied as a part of the query process when
responding to a data request. The default value for data stored and
maintained by the BLM will be 'BLM -- BUREAU OF LAND MANAGEMENT'. This
is because the BLM will be considered the source of any data that it
provides in response to a query.

Attribute Definition: Annual or cyclic cost of work performed to
maintain serviceability, or to repair failures during the year in which
they occur. Includes preventive and/or cyclic maintenance performed in
the year in which it is scheduled to occur.

Notes: Protocol applicable for all four ITDS cost attributes: Each
agency should use its own costing approach and be able to justify the
results. There is no intention of developing an interagency costing
approach. At the interagency level, this attribute provides agency lump
sum costs, not a detailed cost break-down.. \$ (recorded in dollar
amount). This attribute may be a stored attribute but since most
agencies do not store financial information with the geospatial data, it
may be noted what database or system the information should be extracted
from prior to the exchange of data with other groups.

7\. COST ANNUAL/CYCLIC OPERATIONS

Attribute Definition: Annual or cyclic cost of operational activities
related to the normal performance of the functions for which a fixed
asset or component is intended to be used.

Notes: Refer to agency definitions for operations tasks and associated

attribute but since most agencies do not store financial information
with the geospatial data, it may be noted what database or system the
information should be extracted from prior to the exchange of data with
other groups.

8\. COST DEFERRED MAINTENANCE

Attribute Definition: Costs resulting from [maintenance that was not
performed]{.underline} when it should have been or when it was scheduled
and which, therefore, was put off or delayed for a future period.

Notes: \$ (recorded in dollar amount) This attribute may be a stored
attribute but since most agencies do not store financial information
with the geospatial data, it may be noted what database or system the
information should be extracted from prior to the exchange of data with
other groups.

9\. COST LAST UPDATED

Attribute Definition: Fiscal year that cost data was last updated.

Notes: Fiscal Year (4-character numeric: yyyy) For example: 2006. This
attribute may be a stored attribute but since most agencies do not store
financial information with the geospatial data, it may be noted what
database or system the information should be extracted from prior to the
exchange of data with other groups.

10\. COST IMPROVEMENT/ CONSTRUCTION

Attribute Definition: Cost of construction, installation, or assembly of
a new fixed asset, or the [significant alteration]{.underline},
[expansion]{.underline}, or [extension]{.underline} of an existing fixed
asset to accommodate a change of purpose.

Notes: \$ (recorded in dollar amount) This attribute may be a stored
attribute but since most agencies do not store financial information
with the geospatial data, it may be noted what database or system the
information should be extracted from prior to the exchange of data with
other groups.

11\. COUNTY

Attribute Definition: The County, Borough or Parish in which the trail
or trail segment physically resides.

Notes: This attribute is required for all trail types. The appropriate

This attribute may be a stored attribute or one that is derived in a
geospatial overlay operation.

12\. DESIGNED USE

Attribute Definition: The intended use that controls the desired
geometric design, and determines the subsequent maintenance parameters
for the trail.

Notes: Only one Designed Use can be identified per trail or trail
segment. The Designed Use attribute is applicable to all trails, except
for those NHT segments that are not managed for recreation trail
traffic. Each agency will use its own technical construction and
maintenance specifications for the identified Designed Use.

USFS will not use 4WD as this is not a currently defined USFS Designed
Trail Use; nor will it use NSPC as the identification of Designed Use is
required for each USFS trail.

NPS will not use 4WD as this is not a NPS Designed Trail Use.

BLM will currently default populate Designed Use with NSPC - Not
Specified

  -----------------------------------------------------------------------
  List of Values

  ATV - ALL TERRAIN VEHICLE

  BIKE - BICYCLE

  DOG - DOGSLED

  4WD - FOUR WHEEL DRIVE

  HIKE - HIKER/ PEDESTRIAN

**Example: Pack and Saddle / Trail Class 2**\
\
ParkLand Forest Trail #123 is a single-track trail that\'s closed to all
motorized use.\
\
Although there are no restrictions on non-motorized uses and all
non-motorized use is allowed (i.e. mountain bikes, llamas, etc.), the
trail is [actively managed]{.underline} for Pack and Saddle, and Hike /
Pedestrian use. The trail is also managed as a Trail Class 2.\
\
Of the two actively **Managed Uses**, Pack and Saddle use generally
requires a greater clearing width, height, switchback turning radius,
etc. Pack and Saddle use is therefore determined to be the **Designed
Use** or the \"design driver\" that controls the desired geometric shape
and subsequent maintenance parameters of the trail. Agency-specific
technical specifications or **Design Parameters** for Trail Class 2 Pack
and Saddle will provide the technical construction and maintenance
parameters for the trail (i.e. tread width, surface, grade, cross-slope,
clearing, turns, etc.).

ususally is the same as Admin Org, but not always (as in the case of
trails meandering across agency or unit boundaries, where an agreement
has been established for one entity to take lead management
responsibility for the trail). For NSTs and NHTs, this attribute
represents the \"trail manager\" for that trail segment, and may or may
not be the same as the NHT/NST Trail Administrator.

SEE "TYPE OF SITE" List of Values

(Beginning on page 25)

\* **[The type of trail (or aspect of an NHT) that the Core Question
applies to]{.underline}**:

Regular Trail: Any agency-managed trail that is not a congressionally
designated NST or NHT

NST: Congressionally designated National Scenic Trail

NHT^1^ (Desig): Route/s that are congressionally designated as a
National Historic Trail

NHT^2^ (HR): NHT-associated heritage resources (routes and/or sites)

NHT^3^ (Rec): NHT-associated recreation or interpretive route and/or
site

\*\* **[Attribute applicable to associated NHT heritage resource route
or NHT recreation/interpretive route (trail or road)]{.underline}**. Not
applicable to associated NHT sites.

**[Data Parameters Definitions]{.underline}**

**[Null / Not Null]{.underline}**\
\
**Null**- This entry means that the field may have a null value as an
entry. This means that the attribute field can be left blank and have no
data.\
\
**Not Null**- This entry means that there must be a value entered for
each and every row for this attribute field. Most of these attributes
have been provided with a default value which in many cases is the
equivalent of an \'unknown\'.

**[Overlap Allowed?]{.underline}**\
\
**No Overlap Allowed:** Only one attribute value or LOV code may be
recorded at any given location along the trail or trail segment.
Multiple segments may be identified, each with the appropriately
corresponding LOV.\
\
**Allow Multiple Entries:** More than one attribute value or LOV code
may be recorded, if applicable, at any given location along the trail or
trail segment. Multiple segments may be identified, each with the
appropriately corresponding LOV(s).\
\
The following data attributes may be recorded with more than one
attribute code identified for the same location: Land Use Plan, Managed
Use, NHRP Criteria, National Trail Designation, Prohibited Use, Shared
System, Special Management Area, Type of Route, and Visitor Facility
Type.\
\
**Example:** For any particular stretch of trail, that portion of trail
is physically located in only one County at that location, while that
same location on the trail may have one or more Prohibited Uses.
Therefore, there is no overlap allowed for the data attribute for
County\-- only one County may be recorded for that specific location
(either the trail segment, or entire trail if applicable). The data
attribute for Prohibited Use, however, does allow the entry of multiple
values, if more than one actively Prohibited Use is defined for any
given stretch of trail. In this case, only one County (i.e. Mineral
County) could be recorded in any single location, but all Prohibited
Uses would be recorded for that same location (i.e. ATV, Motorcycle).\
\
The Beginning Measure Point (BMP) and Ending Measure Point (EMP) would
not necessarily be the same for these two data attributes. For example,
the trail may be in Mineral County from BMP 0.00 to EMP 6.42 (recorded
in miles), while the Prohibited Uses of Motorcycle and ATV may extend
for the entire length of the trail from BMP 0.00 to EMP 16.75.
