arcs

Characteristics of the arc features in coverage noatakgeol are coded in noatakgeol.aat, the arc attribute table. The .aat consists of the following items: ARC-CODE and LTYPE.

Label Definition
ARC-CODE ARC-CODE is a positive integer value (3 3 I) item in the arc attribute table. Values range from 1 to 104. ARC-CODE identifies a stratigraphic boundary, fault, or other linear feature. The ARC-CODE is described by the item LTYPE.
LTYPE LTYPE is a character field (30 30 C) in the arc attribute table. LTYPE describes the type of arc.

polygons

Characteristics of the polygon features are coded in the polygon attribute table. Table noatakgeol.pat includes the following items: CLASS, FORMATION (geologic unit label), NAME (geologic unit name), and COMPOUND.

Label Definition
CLASS CLASS is a positive integer value (4 5 B) item in the polygon attribute table. Values range from 1 to 263. Every unique unit has a unique CLASS value. Each CLASS value listed below is defined by the information from the FORMATION (12 12 c) item which contains the geologic unit label if one was assigned, and by the NAME (120 120 c) item which gives the name of the unit. Map units shown in parentheses indicate thin and generally discontinuous deposits above near-surface bedrock. Unit labels containing a slash indicate compound units where one unit is stratigraphically above another. Units queried where uncertain.
COMPOUND COMPOUND is a positive integer value (3 3 i) item in the polygon attribute table. Values range from 0 to 1. Compound units are map units shown with slashes that indicate deposits of the first unit above known or inferred deposits of the second unit.

points

Characteristic of point features in coverage btpoint are coded in btpoint.pat, the point attribute table. The .pat includes the following items: DESCRIPTION and CODE.

Label Definition
CODE CODE is a positive integer value (4 3 B) item in the point attribute table. Every unique type of point has a unique CODE value. Each CODE value listed below is described and then defined by the information from the DESCRIPTION item.
