BLMpca.pat is the Arc/Info polygon attribute table for the coverage.
Resource_area and district are user defined items. Resource_area is an
item containing the text attribute value corresponding to the name of
the BLM Resource Area (now called Field Office Area) defined by the
arcs of the polygon. District is an item containing the text attribute
value corresponding to the name of the BLM District that the Resource
Area (Field Office) is within. Users should note that in 1997 the BLM
did away with all Districts, except the California Desert District. All
other Field Offices now report directly to the State Office in Sacramento,
but have administrative support (such as budget) in a regional staff.
There is a northern (Norcal) and a center (Central California) staff.

BLMpca.aat is the Arc/Info arc attribute table for the coverage.
Items Amin_level, coord_source, and def_feature are user defined items.
Admin_level is used to indicate if the boundary is only a resource area
boundary, or if it is also a district or regional boundary. Coord_source
is used to indicate the source of the arc and vertices. Vaules include
100,000 DLG, 24k DRG, etc. Def_feature documents the feature natural or
man made feature upon which the boundary is based. Values include highway,
county boundary, stream, etc.

BLMpca.patdistrict is a regions attribute file used to put the field
office (Resource Area) boundaries into District/regional office regions
so that these administrative areas may be illustrated or used in
inventories as one entity rather than three or more field offices.
The item District contains the name of the District or regional
administration area.

BLMpca.taradmin_level is used in setting up routes on the boundaries.
The item admin_level defines the administrative level of the boundary:
resource area (field office) or district (regional). This is done so
that resource area boundaries, district boundaries, and the state
boundary may be symbolized cartographically as distinct features.

BLMpca.secadmin_level is used in the extende Arc/Info data model
in establising routes on the administrative boundaries. Stbnd_feature
is the only item that is not software defined. Values storred in this
table are used to define the state boundary, and what feature it is
coinciedent with at any where along the boundary: resource area,
district, coast, international border, etc.

BLMpca.tatresource_area is used to provide cartographic information
regarding the offset of feature labels for illustration. Symbol tells
Arc/Info which symbol to plot, size gives the sizing of the symbol.
Text provides the text to be plotted for the feature. Justify tells
Arc/Info whether to left, center, or right justify the text. Offsetx
and offsety give text placement information to avoid over posting.
