A national BLM GTLF data standard is essential for collecting the landscape-scale data necessary to identify management opportunities and challenges that may not be evident when managing smaller land areas. GTLF data not only serve the crucial function of improving BLM transportation planning, but is also invaluable to numerous other BLM programs affected by transportation (e.g. water and air quality, wildlife habitat fragmentation, engineering, realty, cultural resources).The purpose of the GTLF data standard is to help support the BLM mission in a wide spectrum of subject areas. The GTLF data standard will also provide BLM programs with a better understanding of the impact of transportation on their programs. The national GTLF standard allows for the capture of data from the Travel Management Plan (TMP) as well as from observed route usage.BLM Colorado Ground Transportation Linear Features (Roads & Trails)
