Introduction

This is a Superprocess and running it may have an effect on other Datamine files in the project. More...

 

The QUICKEST process interpolates grades into a block model using basic calculations.

 


Notes

This command is found in Studio EM and Studio UG to support processes requiring precursory interpolation methods, such as IsoShell generation.

It can also be called independently from the command line.

Description

PROTO

Input

Yes

Block_Model_File

Input model prototype.

This is a standard block model file containing the 13 compulsory fields. It may also contain the rotated model fields. If it includes cells then it must be sorted on IJK.

IN

Input

Yes

Table

Input sample data. This must contain X,Y and Z fields and at least one grade field.

Description

Source

Required

Type

Default

X

X coordinate of sample data in IN file. If not specified, then X is assumed. If the unfolding option is used, then the X coordinate must be set to the unfolded UCSA coordinate.

IN

Yes

Numeric

X

Y

Y coordinate of sample data in IN file. If not specified, then Y is assumed. If the unfolding option is used, then the Y coordinate must be set to the unfolded UCSB coordinate.

IN

Yes

Numeric

Y

Z

Z coordinate of sample data in IN file. If not specified, then Z is assumed. If the unfolding option is used, then the Z coordinate must be set to the unfolded UCSC coordinate.

IN

Yes

Numeric

Z

VALUE Name of the field containing the grade to be estimated IN Yes Alphanumeric Undefined
NUMSAM Name of the field to be created in the output MODEL file which is used to record the number of samples used for estimating each cell. If a field name is not specified the number of samples used will not be recorded. - No Alphanumeric Undefined
ZONE Name of the zonal interpolation field. The field may be numeric or up to 20 character alphanumeric. The field must exist in both the PROTO and IN files. If it is specified then cells in each ZONE will be interpolated using only samples with the same ZONE value. - No Alphanumeric Undefined
LENGTH Name of the field used for length weighting of samples. This is only used if the Inverse Power of Distance interpolation method is selected (IMETHOD=2). - No Alphanumeric Undefined

MINNUM

Minimum number of samples which must lie within the search ellipsoid in order for the model subcell to be estimated. If there are less than the minimum number and the input PROTOmodel contains cells, then an absent data value will be assigned to the grade field in the output model file MODEL If there are less than the minimum, but the input PROTOmodel does not contain any cells, then a cell will not be created in the output model file MODEL.

No

No
