Summary of Dialogs

Advanced Estimation dialogs overview

Advanced Estimation - Dialogs

This document outlines the dialogs you may encounter whilst using the Advanced Estimation (AE) module in your application. Each dialog description is supported by a link to more detailed help.

Note: Advanced Estimation is part of the Studio RM toolset. Additional licensing modules aren't required.

  • Scenario:
    • Scenario Setup: create a new estimation scenario, save a copy, edit or delete an existing one. At any stage in the estimation process one or more copies of the current scenario (all inputs and outputs) can be saved.  Alternative options can then be tested on these new scenarios and the effect of the changes analyzed.

      This panel is also used to optionally import Datamine Supervisor project data and/or specify if Supervisor will be used for variography/KNA More...
  • Samples:
    • Select Samples: choose the sample file and grade/variable field(s)for your estimation case.More...
    • Define Custom Zones: configure different combinations of sample zones for the estimation of soft boundaries. This panel also shows useful summary statistics relating for multiple zone selections (as part of 'soft boundaries' estimation). More...
    • Bivariate Statistics: generate summary statistics for zone or zone combinations. More...
  • Variography: (these panels are only visible if Supervisor data is not being imported)
    • Investigate Anisotropy: create a 3D block model of variogram values and rotate orthogonal planes through the model displaying the variogram contours.  The results can significantly help to identify the directions of the major, minor and intermediate axes of anisotropy. More...
    • Create Variograms: calculate both experimental variograms and cross-variograms. More...
    • Fit Models: display and analyze your experimental variograms.  Use the dynamic lag control to identify the optimum lag distance. Variogram models can be fitted automatically or manually or a combination of both.  The models are then saved for input to the estimation process. More...
  • Kriging Neighborhood Analysis (KNA): (these panels are only visible if Supervisor data is not being imported)
    • Select Locations: define one or more locations in the model volume to create the test cells to be used for the KNA study. More…

    • Optimize: calculate and display KNA statistics for the test cells and determine the optimum parameters. More…

  • Estimation:
    • Select Prototype: select a previously defined prototype model (e.g. using create-model-prototype), and display a summary of samples and cells per zone. More...
    • Parameters: import predefined parameter files to use in the current estimation run. More...
    • Define Estimations: configure new or existing estimation runs. You can define an estimation by its type, variables, zones and/or many other parameters. You can also copy estimations to new items in order to adjust existing parameters and assess the results. If candidate models were provided in the Fit Models panel, you can retrieve them here also for the purpose of setting up an estimation. More...
    • Review Variograms: view and assign variograms to each estimation defined in the previous step. If candidate models have been selected, this assignment will be automatic. More...
    • Select Search Volumes: view, assign and edit search volumes and parameters, and (optionally) import/export search volumes. You can also use this panel to set up grade capping parameters. More...
    • Run Estimation: the dialog gives a summary of the files, fields and parameters that have been selected for the run.  If any changes need to be made return to the appropriate dialog and edit as required.  Otherwise click Run Estimation to create the block model. More...

    Advanced Estimation: 2D vs. 3D Data

    Advanced estimation can be performed using 2D or 3D data. Where samples with 2D data have been selected, panel behavior will be adjusted in some cases to ensure inputs the function are valid.

    For example, axes for which it is not possible to rotate around are disabled when computing the variograms and fitting the models, and the Investigate Anisotropy panel will only display a single isocontour plot where 2D data has been specified. Other adjustments are made internally to ensure 2D data is processed correctly, particularly with regards to calculations involving rotation.
