This data set is derived from the LAND data set produced by the Arizona State Land Dept., Arizona Land Resource Information System (ALRIS). BLM has reduced the complexity of the data set by removing all data except for the surface management information. The LAND data set was first started in 1984 and updated in the spring 1988 by the State Land Department Forestry Division and ALRIS. The PLSS data originated from the Department of Transportation (ADOT). The data was then projected into ARC/INFO format and edited using the procedures from the ASLD 'Land Status Map Digitizing Procedure' guide. The data set covers the entire State of Arizona. Changes in federal agencies are done primarily through the Bureau of Land Management (BLM). BLM incorporates its changes as well as others such as the Forest Service, Bureau of Reclamation, Fish & Wildlife Service, National Park Service, etc. BLM and State of Arizona status is updated approximately every six months, other agencies are updated on an irregular basis.

The state land ownership portion of the land coverage is updated along with the surface parcels coverage. All changes to the surface parcels are performed by the CAD department. They are then given to the GIS department in a DXF file on a township by township basis. Through a series of AMLs and editing procedures, the changes in the DXF file are incorporated into the surface parcels and land coverages. Changes in federal agencies are done primarily through the Bureau of Land Management (BLM) using a customized AML based application of ArcInfo. BLM incorporates its changes as well as others such as the Forest Service, Bureau of Reclamation, Fish & Wildlife Service, National Park Service, etc. BLM and State of Arizona status is updated approximately every six months, other agencies are updated on an irregular basis.

Data is obtained from both the Bureau of Land Management and Bureau of Indian Affairs on a somewhat regular basis and incorporated into the land coverage as necessary. Sometime we get actual GIS data and other times we get textual information concerning township and ranges that need to be modifed for or added to a specific land owner.
An ArcInfo AML is then run to dissolve the LAND coverage into land ownership boundaries.
