Description

Lines delineating electric transmission lines through the state of Oregon. Electrical transmission lines were derived originally from 1:24,000 scale DLG's, supplemented by digitizing from DRG's. Updated in 2005 by digitizing lines for the North and South Cascades Protection maps, and again in 2009 with dvof (vertical obstruction), BPA, and Lidar data. Many transmission lines appear incomplete due to lack of data in those areas.
For Cartographic display and air hazards reference.
