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.

Parameters

oIPJ1

Type: GeoEngine.Core.GXNetCIPJ
IPJ 2

Return Value

Type: Int32
0 - No 1 - Yes, either because both CS are on the same datum, or because a local datum transform is defined for each coordinate system.
