Data Import A quick start guide for NPVS data importing

Import Data: Quick Start

Import commands are found in the Optimization control bar's Import Data group. Some of these commands can also be accessed using the Optimization ribbon's Import group.

At a high level, the process of importing data for a strategic planning project is:

1. Load the planning block model. The exact procedure for selecting a file depends on the format you are importing, however, importing generally involves selection of a physical file and then attribute selection (you can import all or a subset of attributes - useful if your model contains information you don't need).

2. Assign data fields to Studio NPVS parameters. The dialog displays a grid box with two columns; Field and Assigned To. You assign model fields to parameters by editing cells in the Assigned To column. Note that “not assigned” fields will not be imported.
   
   There are three easy ways of editing cells in the Assigned To column:

3. • Click the arrow icon displayed in a cell when the cell is selected, and choose a parameter from the list.

   • Type the first letter of the parameter label, for example 'A' for 'Attribute'.

   • Copy and Paste the parameter labels.

   The Assign Fields dialog...

4. Select the Data type of the element fields (Products and Attributes). Product fields can be defined as grade, percentage or mass. Attribute fields should be defined as grade or percentage only.
   
   The Assign Elements dialog...

5. Define your units of measure: rock mass unit, volume unit and element mass units. Note that gold mass units can be grams but not gram/ton. The units of elements imported as [percentage] are set automatically to rock mass unit.
   
   The Define Units dialog...

6. Define defaults. You must define a nonzero default density if none of the model fields has been assigned to [Density], [Tonnage Factor] or [Tonnage]. The rock mass formula is commonly customized when importing a topography percentage field as [Volume]:

7. • If the field defines a fraction of a block below topography, set the factor to the maximum volume of a block, which is equal to the product of block dimensions in X, Y, and Z directions i.e. tonnage factor = X * Y * Z.

   • If the field defines a percentage of a block below topography, set the factor to the maximum volume of a block divided by 100 i.e. tonnage factor = X * Y * Z / 100.

8. Consider reblocking if the block model is very large.

9. An Import Summary is presented upon the completion of the process.
