CIPJiCompareDatums Method

Compare the datums of two coordinate systems?

Namespace:  GeoEngine.Core.GXNetX
Assembly:  geoengine.core.gxnetx (in geoengine.core.gxnetx.dll) Version: 2024.2.0.25
Syntax
Copy
public int iCompareDatums(
	CIPJ ipj2
)

public int iCompareDatums(
	CIPJ ipj2
)

Parameters

ipj2
Type: GeoEngine.Core.GXNetXCIPJ
IPJ 2

Return Value

Type: Int32
0 - Datums are different 1 - Datums are the same, but different LDT 2 - Datums and LTD are the same
Remarks
To transform between different datums requires the use of a local datum transform. The local datum transform can be defined when a coordinate system is created, but the definition is optional. This function will test that the local datum transforms are defined. Note that a coordinate transformation between datums without a local datum transform is still possible, but only the effect of ellipsoid shape will be modelled in the transform.
