SLC PAT

The Polygon Attribute Table (PAT) provides the linkage between geographic locations (polygons) and soil landscape attributes in the associated database tables.

  Field  Name      Type  Width
  -----  ----      ----  -----
    1    AREA        F     4
    2    PERIMETER   F     4
    3    SLC#        B     4
    4    SLC-ID      B     4
    5    SL          I     6    (relate key)
    6    LRA         I     4    (relate key)

Relationships

• A record in this file is unique with respect to SLC#.
• The SL field is used to relate to the soil and landscapes databases.
• The LRA field is used to relate to the Ecostratification databases.

Note: since SLC polygons are occasionally split by LRA lines, SL numbers are not necessarily unique in this file. Also, since LRAs typically include many SLC polygons, LRA numbers are almost never unique in this file. A concatenation of SL & LRA will almost invariably uniquely identify one polygon.
