This featureclass represents the Bureau of Land Management (BLM) surface management agency (SMA) footprint for Arizona. SMA was originally derived from the land dataset produced by the Arizona State Land Dept (ASLD), and the Arizona Land Resource Information System (ALRIS). The land dataset was initiated in 1984 and updated in the spring of 1988 by the State Land Department Forestry Division and ALRIS. The data was then projected into ARC/INFO format and edited using the procedures from the ASLD Land Status Map Digitizing Procedure guide. The land dataset covers the entire State of Arizona and includes surface management, public land survey system (PLSS) provided by the Department of Transportation (ADOT), and county and state boundaries.
