Soil Layer File (SLF)
The Soil Layer File is designed to handle attributes which vary in a vertical direction.Relationships
- A record in this file is unique with respect to PROVINCE + SOIL_CODE + MODIFIER + LU + LAYER_NO.
- This file can be linked to the SNF by PROVINCE + SOIL_CODE + MODIFIER + LU and to the SMUF by PROVINCE + SOIL_CODE + MODIFIER.
