See this process in the Command Table.

Process Overview

Note: This is a superprocess and running it may have an effect on other Datamine files in the project.

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.

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
