Estimation Parameter File
This topic is part of the Grade Estimation range of topics.
The following table summarizes the fields in the Estimation Parameter file. Only fields VALUE_IN and SREFNUM are compulsory; if other fields are not included in the file then their default values are used.
The field names for the Zone fields are enclosed in { ... }. This signifies that this is not the actual name of the field in the file; the actual name you should use is the name of the Zone field that is included in your Input Sample and Input Prototype Model files e.g. ROCK or FLTZONE.
The default value of the VALUE_OU field is the name you have specified as the VALUE_IN value.
The Estimation Parameter File contains the following fields:
