APTOTRUE |
|
This is a Superprocess and running it may have an effect on other Datamine files in the project. More... |
Introduction
APTOTRUE is designed to be used in conjunction with processes ANISOANG and ESTIMA when the apparent dip angle and the true dip direction angle have been interpolated into a model and the true dip angle is required in order to use the Dynamic Anisotropy option to estimate grades. In fact the input file can be any type of file, so long as it contains the apparent dip and true dip direction fields.
The process takes as input the file IN containing fields APDIP (apparent dip) and TRDIPDIR (true dip direction) and parameter APDIPDIR (apparent dip direction) and calculates the TRDIP (true dip) field which is written to file OUT. Parameter APDIPDIR is the azimuth of the sections corresponding to the apparent dip field.
Further information and examples are available in the Dynamic Anisotropy User Guide.
Files, Fields and Parameters
Input Files
Name | I/O Status | Required | Type | Description |
IN | Input | Yes | Undefined | Input file containing the true dip direction and the apparent dip angle fields. |
Output Files
Name | I/O Status | Required | Type | Description |
OUT | Output | Yes | Undefined | Output file containing all the fields in the input file plus the true dip angle. |
Fields
Name | Description | Source | Required | Type | Default |
APDIP | Apparent dip angle. If not specified then APDIP is assumed. | IN | No | Numeric | APDIP |
TRDIPDIR | True dip direction angle. If not specified then TRDIPDIR is assumed. | IN | No | Numeric | TRDIPDIR |
TRDIP | True dip angle. If not specified then TRDIP will be created. | OUT | No | Numeric | TRDIP |
Parameters
Name | Description | Required | Default | Range | Values |
APDIPDIR | Apparent dip direction angle in degrees. This is the azimuth of the sections on which the original string data was digitised. | Yes | 0 | 0,360 | Undefined |
Notes
The process is implemented as a 'Super Process'. This means that it is actually constructed as a macro/menu, but is run as a normal process with input from files, fields and parameters as defined in its help file.
Example
!APTOTRUE &IN(APPMOD),&OUT(TRUEMOD),@APDIPDIR=180
APTOTRUE
... calculating true dip angle
Calculation of true dip angle complete
- output file TRUEMOD created with 3313 records
- mean true dip angle = 17.97
- number of absent true dip values = 0
