  1. InteragencyTrail Data Standards USDA Forest Service ▪ Bureau of Land Management National Park Service ▪US Fish and Wildlife Service

  2. Getting It… Together Development of the “ITDS” • Requested by Interagency Trails Council • Establish a common set of data standards • Applicable to all agency-managed trails

  3. Data Dictionary or Database? Interagency Task: • Develop standardized GPS Data Dictionary? • Develop standardized database? • Develop a core set of common data standards?

  4. Data Dictionary or Database? Interagency Task: • Develop standardized GPS Data Dictionary? • Develop standardized database? • Develop a core set of common data standards?

  5. Data Dictionary or Database? Interagency Task: • Develop standardized GPS Data Dictionary? • Develop standardized database? • Develop a core set of common data standards?

  6. Data Dictionary or Database? Interagency Task: • Develop standardized GPS Data Dictionary? • Develop standardized database? • Develop a core set of common data standards ….that can be incorporated into data dictionaries or databases

  7. Trail… What’s a Trail? Interagency Trail Definition: A linear route managed for human-powered, stock, or OHV forms of transportation or for historic or heritage values.

  8. Factors to Consider • Interagency core data set • Data aren’t cheap! • Standardized terminology • Existing, standardized data attributes • Implementation feasibility & timeframes

  9. ITDS Attribute Review Criteria Does (or is) the Attribute… • Relate to a core interagency question? • Of national, regional or statewide significance? • Provide data needed to meet applicable laws, regulations and/or policies? • Address key congressional, OMB and department-wide reporting requirements? • Currently available or obtainable?

  10. What Do We Want To Know? Interagency Trail Questions • Basic Trail Information (trail name, length, location, etc.) • Management Information (trail uses, accessibility status, condition, cost, etc.) • Additional NST / NHT Questions (trail administrator, certified sites and segments, etc.)

  11. Answering the Questions Interagency Trail Data Standards • Data Attribute • Attribute Definition • List of Values (LOVs) • Data Parameters • ITDS Application Protocols • Crosswalk Translation (if needed)

  12. Is the Trail Accessible?Data Standard Example Data Attribute:Accessibility Status Attribute Definition:Accessibility guideline compliance status for the trail or trail segment. List of Values:Accessible Not Accessible Not Evaluated

  13. ITDS Attributes

  14. ITDS Codes Standardized List of Values for each Attribute

  15. ITDS Data Parameters Defined for Each ITDS Attribute • GIS Item Name • GIS Alternate Name • Data Definition (Type & Width) • Attribute Null / Not Null • Multiple Values Allowed?

  16. ITDS Data Parameters

  17. ITDS Attributes 34 3 13

  18. Interagency BenefitsAdditional Benefits of Working Together Interagency Trail Tools • Trail Class • Managed Use • Designed Use • NHT Corridor Concept • NHT Condition Categories

  19. Currently Underway Interagency Trail and GIS representatives currently collaborating on: Federal Trail Data StandardsPublication of the ITDS by the Federal Geographic Data Committee (FY07-FY08)

  20. Upcoming Tasks? • National Scenic Trail Attributes Identify additionally needed NST attributes • Apply ITDS to Long-Distance Trails Provide implementation guidance, suggestions and examples for NST’s and NHT’s • ITDS Implementation Strategy/Schedule For USFS, BLM, NPS, and FWS • Additional Trail Information Attributes Potential expansion of ITDS to include additional trail use & visitor Information

  23. Frequently Asked Questions How are agencies incorporating the Interagency Trail Data Standards? BLM: Adapting the standards into FAMS NPS: Adapting the standards into FMSS FWS: Adapting the standards into SAMMS USFS: Majority of standards incorporated in Infra Trails. Remaining standards planned for Infra Trails or Infra Heritage (for specific NHT attributes)

  24. County B 13.2 County A 24.3 5.6 0.0 Frequently Asked Questions What’s “trail segment” mean? “Trail segment” is used informally to identify the specific portion of trail to which a data attribute refers– or to answer the question being asked…

  25. County B 13.2 County A 24.3 5.6 0.0 Frequently Asked Questions Trail Segment Examples: Trail Length: 24.3 miles(segment 0.0 - 24.3) County:5.6 miles County A; 18.7 miles County B (segment 0.0 – 5.6 and 5.6 – 24.3) Trail Class:13.2 miles Trail Class 3; 11.1 miles Trail Class 2 (segment 0.0 – 13.2 and 13.2 – 24.3)

  26. Frequently Asked Questions What’s “No Overlap Allowed” Mean? No Overlap Allowed: Only one attribute value can be recorded at any given location along the trail or trail segment. Example: County Mile 0.00 – 17.4: Park County Mile 17.4 – 28.3: Grove County

  27. Frequently Asked Questions What’s “No Overlap Allowed” Mean? No Overlap Allowed: Only one attribute value can be recorded at any given location along the trail or trail segment. Example: County Mile 0.00 – 17.4: Park County Mile 17.4 – 28.3: Grove County Overlap Allowed: More than one attribute value can be recorded, if applicable, at any given location along the trail or trail segment. Example: Prohibited Use Mile 0.00 – 28.3: ATVs, Motorcycles, Bicycles

  28. Frequently Asked Questions What about “things along the trail”? • “Things along the trail” include trail structures, amenities, viewpoints, etc. • While potentially valuable data at the trail or agency-specific level, this level of detail was determined to be beyond the scope of the interagencystandards.

  29. Frequently Asked Questions For additional questions, answers and clarification: • Appendix G: Interagency Internal Review • Appendix H: Frequently Asked Questions Posted at www.nps.gov/gis/trails/index.html

  30. Bottom-Line Benefits Interagency Trail Data Standards • Improved communication and efficiency • For our internal and external customers • Through proactive interagency trails coordination and collaboration
