Process Overview

Reserve Category Modeling.

To define reserve categories in terms of the distance of the nearest sample from the centre of a cell. All fields from the input model file are copied to the output model, and in addition 3 extra fields may be added:

  • VALUE - the value of the nearest sample.

  • DISTANCE - the distance of the nearest sample from the cell centre.

  • CATEGORY - a reserve category identifier.

If a field CATEGORY already exists in one of the input files then the CATEGORY field in the output MODEL file will be of the same type (A-alpha or N-numeric) If the field does not already exist then it will be created as an alpha field with a maximum of 4 characters.

Any combination of the 3 fields may be included controlled by the value of parameter RESCAT. The user is prompted to enter reserve category definitions interactively.

If RESCAT = 1,3,4 or 6 then you must define reserve categories in free format: >

  • Category

  • Minimum Distance

  • Maximum Distance

3 data items per line separated by commas. Terminate entry with a blank line or a comma in the first character position. If parameter ELLIPSE is non zero then the weighting parameters are prompted:

>DIP>  

 Dip of Axis 1 (degrees down from horizontal).

>AZIMUTH>  

 Azimuth of Axis 1 (degrees clockwise from Y).

>AXIS 1 >  

 Relative length of Axis 1.

>AXIS 2 >  

 Relative length of Axis 2.

>AXIS 3 >  

 Relative length of Axis 3.

Note: AXIS 1 is in the Y direction, if unrotated. Distances along e.g. AXIS 2 will be multiplied by the ratio AXIS 2/AXIS 1.
