Geographic Sciences

Analysts in the BLM-Idaho Geographic Sciences Group create and maintain statewide master spatial datasets, conduct geographic analysis, and produce internal and external maps and other geo-spatial data products. 

Master Title Plats are updated daily and track the administrative status, rights of way (ROWs), and patents of Federal lands in Idaho.  Cartographers create professional map publications for outdoor signs, brochures and public displays, including the BLM 1:100,000 statewide series of land status maps. 

Contact the Information Access Center at (208) 373-3889 for your assistance with mapping needs.
