Abstract
Regional Trails data set created by combining 31 different data sets and verified with orthophotography where applicable.
Purpose
Regional Trails to be published quarterly for RLIS Lite and provide trail information for various needs. This data set was created specifically for off-road trails and paths, though there are some regional connections that are on-street.
Supplemental information
The schema was created by following the National Recreation & Park Association (NRPA) GIS Model for trails to set a standard among data providers.

Lineage

Process Description
Existing Trails: 31 Data sources provided a base to begin verifying alignment with aerial orthophotography. Attribute data was populated from these source layers. Where there was no attribute data provided, there was thorough research conducted to try and populate the records. Unknown values were used when there was no other information available.
Process date
20100801
Process Description
Future Trails Added: The old RLIS regional planned trails data was incorporated into the new NRPA GIS database. Now all of the trails are maintained in the same database.
Process date
20110201
Process Description
TRAILID field changed from a string to an interger and re-populated in increments of one.
Process date
20140801
Process Description
Added field MTSCOTTLP: Field to flag if a segment is part of the "Mount Scott Loop".

Related data files and field descriptions follow:
Table NameColumnSample Domain ValueDefinition
Trails.sde----Non-RLIS-Lite fields in SDE Trails
YearOpen--Non-RLIS - Year Opened - Year the trail was made available for public use (YYYY)
BikeNetwork--Used for querying trails segments for bike network
No Do not include segment in bike network
No exception Do not include segment in bike network, even if the segment has all other flags consistent from standard "to include" query
Yes Include segment in bike network
Yes exception Include segment in bike network, even if the segment has other flags inconsistent from standard "to include" query
Rating--Non-RLIS - Difficulty Rating - Relative difficulty rating of the trail or trail segment
Easy/FlatA trail requiring limited skill with little challenge to travel - mostly level; adequate width; minor crossings, well marked
ModerateA trail requiring some skill and challenge to travel. Minor ascent/descent; narrow passages; heights; natural crossings; length
Hard/SteepA trail requiring a high degree of skill and challenge to travel. Significant ascent/descents; scrambling crossings; some bouldering, extensive length from trail head to trail access
UnknownUnknown
Created_Date--Date of when the segment was created.
Last_Edited_Date--Date of the last time the feature has been edited, including attribute or geometry changes.
SegmentID--ID to indicate funding source(s).
Slope--Slope of the segment
Last_Edited_User--Name of the user who last made an edit to the feature.
RegPlan--Flag to indicate if the segment is part of a regional trail system.
Bond2006--Flag to indicate if segment was part of the 2006 bond acquisition.
MtScottLp--Flag to indicate if the segment is part of the Mount Scott Loop.
Fortymloop--Flag to indicate if the segment is part of the 40mile loop
Wilrivgnwy--Flag to indicate if segment is part of the Willamette River Greenway.
Trails.dbf ----Attributes and descriptions associated with trails
TrailID--Trail ID - Unique identification number for each trail segment.
TrailName--Trail Name - Proper name of the trail or trail segment. No abbreviations. Access, connector, and spur trail names should use the same name as the main trail, appended with the appropriate suffix, e.g., "Springwater Corridor - connector." Adjacent street names may be used for trail segments in road rights-of-way.
SystemName--System Name - Name of the regional trail if the segment is part of the regional trails and greenways system plan.
SharedName--Shared Name - Other name that the trail or trail segment is know by when the trail/segment is part of more than one route
SystemType--Functional Class - Hierarchical classification by purpose and function. This is analogous to a roadway classification system (interstate highways, arterials, collectors, local streets).
Community Also known as "Community Connector Trails", these are typically much longer than Local trails though not as long as Regional trails. Community Trails link important land uses and areas of interest within a single jurisdiction. Examples are Tigard's "Pathfinder-Genesis Trail", Portland's "Columbia Blvd Trail", or Gresham's "Butler Creek Greenway."
Local Sometimes called "Local Access Trails" or "Neighborhood Trails", these provide connections to local features such as parks, community centers, and schools, and include most paths within parks, natural areas, planned developments, and campuses, as well as public stairways, alleys, and narrow ROWs.
National Inter-state trails, e.g. "Pacific Crest Trail" or "Columbia River Water Trail."
Other The Other value is reserved for GIS trail features that do not exist on the ground but serve to connect trail segments to the GIS routable streets network.
Regional Regional trails tend to be multi-jurisdictional, exceptionally long, and connect to regionally significant features such as Forest Park or the Tualatin River. Examples are the Gresham-Fairview Trail, Hillsdale to Lake Oswego Trail, or the Wildwood Trail.
State Also known as "Inter-regional Trails," "State" trails connect to destinations outside the region, e.g., "Banks-Vernonia Trail" or "Willamette River Water Trail."
County--County - County where the majority of the trail or trail segment physically resides. Use proper county or parish name.
