Project Proposal
Overview
~3,100 miles crossing MT, ID, WY, CO, NM Multiple land management agencies: BLM, NPS, US Forest Service Lead agency = US Forest Service (Lakewood, CO) Lead partner = Continental Divide Trail Alliance (CDTA)
Purpose1. Can multiple agencies utilize the
same data standardization protocol for CDNST?
2. Can database management systems be used across multiple agencies to coordinate CDNST data after collection?
Data Consistency• Varying trail management policies
Different methods/protocols among agencies
Need: Multi-jurisdictional collaboration
• GIS attribute coding disagree
Agency road definitions differ Creates potential for different
interpretation
Need: One method of coding
• Variety of sourcesInconsistent data collection
Need: Systematic data collection
Tool for Managing CDNST• FS Infrastructure database (Infra)
Accountability through
accomplishments
Funding incentives
Spending wisely – future funding
from Congress
• Minimize redundancy to achieve consistency
•Multiple user interface across agency boundaries
Infra’s business flow chart (FS, 2004)
Data Required•Current Infra database access
Why? GIS stored in Infra (data layers, aerials, topos etc.)
•Most up-to-date GIS and Strategic Plan Project Instructions for Completing and Updating CDNST GIS Data
Attribute metadata
•List of key GIS/Infra specialists Within agencies (data collection & integration knowledge)Within the study area (key to pilot project support)
•Most current GIS CDNST dataData needs assessment (pilot project-New Mexico)
Methods• Compare current attributes of CDNST data to standards and criteria for trails
• Use trail data to evaluate Infra in relation to CDNST data
• Redefine data criteria and methods for collecting data
• Determine best technologies for data collection & possible integration into Infra
• Develop, test and modify data dictionaries for collectingCDNST data for populating Infra
• Determine best data dictionary for integration into Infra

Timetable•June-August 08: Compile Trail data standards & criteria
•September-October 08: Complete evaluation of CDNST attributes in a format compatible with Infra
•November 08-February 09: Field work to determine best technologies and evaluate data dictionary
•March-May 09: New Mexico project area data collection using final technology and data dictionary
Develop sample data entry forms for integration into Infra (non-GIS users)
•June-August 09: Final evaluation of data collection method
•September-December 09: Finalize thesis project report
Deliverables
• Final data dictionary for CDNST feature attributes
• Non-GIS Data Entry Form
• User manual for CDNST data collection
