CDUCreateDrillholeParameterWeightConstraintDatabase Method

Used for weighting inversion models.

Namespace:  Geosoft.Desktop.GXNet
Assembly:  geosoft.desktop.gxnet (in geosoft.desktop.gxnet.dll) Version: 2024.2.0.25
Syntax
Copy
public static void CreateDrillholeParameterWeightConstraintDatabase(
	CDB db,
	int ch,
	CREG reg,
	string database
)

public static void CreateDrillholeParameterWeightConstraintDatabase(
	CDB db,
	int ch,
	CREG reg,
	string database
)

Parameters

db
Type: GeoEngine.Core.GXNetCDB
Database (selected lines used)
ch
Type: SystemInt32
Property channel handle [<define>DB_LOCK_READONLY</define>]
reg
Type: GeoEngine.Core.GXNetCREG
Parameters (see notes)
database
Type: SystemString
Output database
Remarks
Control parameters are passed in the REG (to allow for future expansion without the need to modify the wrappers). The input drillhole database must contain current X, Y and Z channels. Drillhole data should be equally spaced (or nearly so) down the hole. Weights are calculated on a circle perpendicular to the hole at each point. RADIUS - Maximum radius from drillhole to create weighting points (Default = 100). INCRMENENT - Grid cell size in weighting circle (Default = 10). MINIMUM - the minimum weighting value to apply, at the radius (Default = 0.0001). POWER - Exponential power to use in the weighting function (negative of this is used) (Default = 2).
