Ground Transportation Data Standard Version 1.0

This information bulletin (IB) announces the availability of the Ground Transportation (GTRN) Data Standard, Version 1.0. This data standard documents the data schema and structure already in use in Oregon/Washington (OR/WA) Bureau of Land Management (BLM) corporate data environment. 

The GTRN dataset represents spatial location and information about OR/WA BLM’s transportation features. Current linear features are represented in GTRN, i.e., routes that are visible on the ground. Permanently removed routes that were part of the recognized transportation system, i.e., the Facility Asset Management System (FAMS), are also represented in GTRN as these routes and their associated attributes remain in the FAMS. Historic linear features that were not in the FAMS and are no longer visible on the ground are not included in the GTRN theme. Railroads and water transportation are not included in the GTRN theme. 

The BLM’s transportation routes provide public and administrative access to BLM managed lands. These routes support recreation, commercial, and administrative use. Many BLM programs affect the composition and use of the route system including engineering, recreation, lands and realty, forestry, minerals, aquatics (water quality and aquatic habitat), wildlife, fire and fuels, invasive vegetation species, and cultural resources. Consistent terminology is provided in GTRN to help align these various program areas and/or planning phases.
