Introduction
Reserve Category Modeling.
How to use
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.

Notes
If RESCAT = 1,3,4 or 6 then the user will be prompted to 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 will be 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. |
[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].
