Transition Attribute Values
The Transition Attribute Values Property specifies, for each transition attribute, the value (per unit area) to be applied when calculating the value of the attribute for each combination of stratum, transition group and age range.
Once Attributes have been defined (under Project Definitions), each combination of attribute type, stratum, transition group and age range is then assigned a numeric value using the Transition Attribute Values property; this value is then used as a multiplier on the area undergoing transitions in order to calculate the corresponding value for each attribute. The transition attribute values are provided for each scenario so that users can vary the way in which attributes are calculated between scenarios.
The fields for the Transition Attribute Values property are:
Iteration (optional)
The Iteration for which the record applies. If left blank then the record applies to all iterations.
Timestep (optional)
The Timestep for which the attribute record applies. If left blank then the attribute record applies to all timesteps. An attribute record continues through time until another Timestep value is encountered by the model for the same state attribute type in the same stratum, at which point the new attribute value will be applied.
Primary Stratum (optional)
The Primary Stratum for which the record applies. If left blank then the record applies to all primary strata.
Secondary Stratum (optional)
The Secondary Stratum for which the record applies. If left blank then the record applies to all secondary strata.
Tertiary Stratum (optional)
The Tertiary Stratum for which the record applies. If left blank then the record applies to all tertiary strata.
Transition Group
The Transition Group for which the record applies.
State Class (optional)
The State Class for which the record applies.
Transition Attribute Type
The Transition Attribute Type for which the record applies.
Age Min (optional)
The minimum age for which the record applies.
Age Max (optional)
The maximum age for which the record applies.
Value
The value (per unit area) to be used when calculating the state attribute for this combination of stratum, state class and age range.
