manitoba pilot area soil property estimates
DESCRIPTION
Examples of maps of soil properties produced by disaggregation of legacy soil polygons using a weighted average approach where the weights are based on fuzzy likelihood values for landform classes with a representative soil associated with each landform class.TRANSCRIPT

Polygon Disaggregation Based on Fuzzy Likelihood Values• New Output
Option– Writes out all
fuzzy likelihood values• For every grid cell• For all defined
classes– Classes can vary
by cell• Every cell can
have different numbers and types of fuzzy classes
• Controlled by a Map Zone identifier
• Rules by Map_Zone
Computes Soil Property Values by Weighted Average Method of Zhu (1996)

Percent Sand
Percent Silt
