BLM AK Ground Transportation Linear Features GTLF within Alaska

The Ground Transportation Linear Feature (GTLF) data standard provides a national geospatial data standard of the ground transportation linear features. 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).
