CIGRFCalcVV Method

Calculate IGRF data VV's for a given IGRF model.

Namespace:  GeoEngine.Core.GXNetX
Assembly:  geoengine.core.gxnetx (in geoengine.core.gxnetx.dll) Version: 2024.2.0.25
Syntax
Copy
public void CalcVV(
	CVV gv_vel,
	CVV gv_vlon,
	CVV gv_vlat,
	CVV gv_vfs,
	CVV gv_vinc,
	CVV gv_vdec

public void CalcVV(
	CVV gv_vel,
	CVV gv_vlon,
	CVV gv_vlat,
	CVV gv_vfs,
	CVV gv_vinc,

Parameters

gv_vel
Type: GeoEngine.Core.GXNetXCVV
Input elevation data (metres)
gv_vlon
Type: GeoEngine.Core.GXNetXCVV
Input longitude data (-180 to 180)
gv_vlat
Type: GeoEngine.Core.GXNetXCVV
Input latitude data (-90 to 90)
gv_vfs
Type: GeoEngine.Core.GXNetXCVV
Output total field
gv_vinc
Type: GeoEngine.Core.GXNetXCVV
Output inclination
gv_vdec
Type: GeoEngine.Core.GXNetXCVV
Output declination
Remarks
Calculate IGRF data (total field, inclination, and declination) for a given IGRF model. The model used will be the same as that obtained with Create_IGRF. All of the VV's should be the same length. The function will abort if they are not. No assumption is made on what data types are contained by any of the VV's. However, all total field, inclination, and declination values are internally calculated as real data. These values will be converted to the types contained in the output VV's.
