GDB to Vector Voxel

Use the GDB to Vector Voxel GX to convert the current Geosoft database to a vector voxel.

GDB to Vector Voxel dialog options

Type	Cartesian: If the vector voxel inclination and declination are not in the database, you most probably have the 3 components defining the vectors in the right-handed Cartesian coordinate system. Rotated: If the vector voxel inclination and declination are in the database, this option is automatically selected and the Inclination and declination entries are auto-populated. You can also manually select Rotated and enter the inclination and declination angles of the predominant field. Vector directions: You can also select the 3 components of the field by providing the inclination and declination at each voxel point, along with the magnitude of the field in that direction.
Contextual Vector Components
X channel Y channel Z channel	If you have selected type Cartesian, you will be prompted to provide three channels comprising the magnitude of the field in the XYZ Cartesian coordinate system. Script Parameter respectively: X -> IMPDBVECVOX .XCHANNEL Y -> IMPDBVECVOX .YCHANNEL Z -> IMPDBVECVOX .ZCHANNEL
Inclination Declination U channel V channel W channel	If you have selected type Rotated, you will be prompted to provide the field magnitude of the 3 vector components, along with the predominant field direction. The predominant field direction is defined wit h2 angles, Inclination and declination, and must be supplied. If the vector voxel inclination and declination are in the database, the Inclination and declination entries are populated. You can also manually select Rotated and enter the inclination and declination. In the rotated system, the field components are designated as: Script Parameter respectively: U-> IMPDBVECVOX .XCHANNEL V -> IMPDBVECVOX .YCHANNEL W -> IMPDBVECVOX .ZCHANNEL
Amplitude channel Inclination channel Declination channel	If you have selected type Vector directions, you will specify the magnitude of the field at each voxel point, along with its direction defined as a pair of Inclination and declination channels. Script Parameter respectively: Amp -> IMPDBVECVOX .XCHANNEL Inc -> IMPDBVECVOX .YCHANNEL Dec -> IMPDBVECVOX .ZCHANNEL
Output vector voxel	Enter or browse for the output vector voxel file. By default, the output vector voxel is given the same name as the input database. Script Parameter: IMPDBVECVOX . VOXEL

Type

Cartesian: If the vector voxel inclination and declination are not in the database, you most probably have the 3 components defining the vectors in the right-handed Cartesian coordinate system.

Rotated: If the vector voxel inclination and declination are in the database, this option is automatically selected and the Inclination and declination entries are auto-populated. You can also manually select Rotated and enter the inclination and declination angles of the predominant field.

Vector directions: You can also select the 3 components of the field by providing the inclination and declination at each voxel point, along with the magnitude of the field in that direction.

Contextual Vector Components

X channel

Y channel

Z channel

If you have selected type Cartesian, you will be prompted to provide three channels comprising the magnitude of the field in the XYZ Cartesian coordinate system.

Script Parameter respectively:

X -> IMPDBVECVOX .XCHANNEL

Y -> IMPDBVECVOX .YCHANNEL

Z -> IMPDBVECVOX .ZCHANNEL

Inclination

Declination

U channel

V channel

W channel

If you have selected type Rotated, you will be prompted to provide the field magnitude of the 3 vector components, along with the predominant field direction. The predominant field direction is defined wit h2 angles, Inclination and declination, and must be supplied. If the vector voxel inclination and declination are in the database, the Inclination and declination entries are populated. You can also manually select Rotated and enter the inclination and declination. In the rotated system, the field components are designated as:

Script Parameter respectively:

U-> IMPDBVECVOX .XCHANNEL

V -> IMPDBVECVOX .YCHANNEL

W -> IMPDBVECVOX .ZCHANNEL

Amplitude channel

Inclination channel

Declination channel

If you have selected type Vector directions, you will specify the magnitude of the field at each voxel point, along with its direction defined as a pair of Inclination and declination channels.

Script Parameter respectively:

Amp -> IMPDBVECVOX .XCHANNEL

Inc -> IMPDBVECVOX .YCHANNEL

Dec -> IMPDBVECVOX .ZCHANNEL

Output vector voxel

Enter or browse for the output vector voxel file. By default, the output vector voxel is given the same name as the input database.

Script Parameter: IMPDBVECVOX . VOXEL

Application Notes

In addition to the XYZ location channels, at least one of the following sets of 3 channels must be present in the input database, in order to run this GX successfully.

VX, VY, VZ: The magnitude of the X, Y and Z components in the Cartesian system.
VU, VV, VW: The magnitude of the 3 components in the rotated coordinate system.
Amp, Inc, Dec: The amplitude, inclination and declination of the vectors.
