CVVUNoiseCheck Method

Check on deviation of data from variable background in a VV

Namespace:  Geosoft.Desktop.GXNetX
Assembly:  geosoft.desktop.gxnetx (in geosoft.desktop.gxnetx.dll) Version: 2025.1.0.25
Syntax
Copy
public static void NoiseCheck(
	CGXNETCore gxNetShared,
	CVV vv_i,
	CVV vv_f,
	double all_tol,
	int num
)

public static void NoiseCheck(
	CGXNETCore gxNetShared,
	CVV vv_i,
	CVV vv_f,
	double all_tol,
	int num
)

Parameters

gxNetShared
Type: GeoEngine.Core.GXNetXCGXNETCore
A shared CGXNETCore
vv_i
Type: GeoEngine.Core.GXNetXCVV
Input VV on which to apply quality control Required in <define>GS_DOUBLE</define> or <define>GS_FLOAT</define>
vv_f
Type: GeoEngine.Core.GXNetXCVV
Output flag VV with result 0 and 1. Required in <define>GS_BYTE</define>
all_tol
Type: SystemDouble
Allowed deviation over a number of data points in input VV (next parameter). Must be >= 0.0
num
Type: SystemInt32
Number of data points. Must be > 0
Remarks
This function checks vertical deviation of data in input VV against a moving straight line. The straight line at any time is defined by two extreme points of a data segment. Output VV will be 0 if data point in input VV falls within the deviation, otherwise, it will be 1. Output VV will be 0 if the straight line is vertical.
