AGRASID41 soil landscape polygons classified by Land Systems GIS coverage
AGRASID land systems classification are associated with AGRASID soil landscape polygons by joining to the table that describes the many to one relationship between an AGRASID soil landscape polygons and a corresponding AGRASID land system using the primary / foreign key called POLY_ID.

|---|---|---|---|---|
| OBJECT ID | Objectid | Numeric | Internal identifier | |
| SHAPE | Geometry | Na | Geographic shape object | |
| POLY_ID | Numeric | Long | Soil polygon number, assigned by a soil analyst (PK) |
The AGRASID soil landscapes to AGRASID land system; relationship table (ag41sl2ag41lslg) describes the relationship between one or more soil landscapes and a land system.
AGRASID_41_SoilLandscape polygons link to ag41sl2ag41lslg attribute table through the POLY_ID primary \ foreign key field.

Appendix 2
AGRASID41 LandSystem polygons
This is information about AGRASID land system spatial data and the associated legend table.
The AGRASID41 land system polygons and legend table (AGRASID41_LandSystemLegend) table contain data that describe land system features.
Previous versions of AGRASID did not contain a distinct land system spatial data set. Rather AGRASID soil landscapes each belonged to a land system. Users of AGRASID looking for a spatial representation of land systems generated there own land system spatial data by DISSOLVING AGRASID soil landscapes themselves based on the “LSLGDSYM” field. Appendix 1, table 2 of this document, contains the structure AGRASID soil landscapes to land system legend relationship table (ag41sl2ag41lslg).
