Gets a boolean indicating if grid-based geographic transformations are available for use in the application. These are installed as part of an ArcGIS Explorer expansion pack.

Namespace:  ESRI.ArcGISExplorer.Geometry

Assembly:  ESRI.ArcGISExplorer (in ESRI.ArcGISExplorer.dll) Version: 2.0.0.1500 (2.0.0.1500)

Syntax

C#
public static bool CanUseGridTransformations { get; }
Visual Basic (Declaration)
Public Shared ReadOnly Property CanUseGridTransformations As Boolean

Field Value

trueTruetruetrue (True in Visual Basic) if grid transformations are available; otherwise, falseFalsefalsefalse (False in Visual Basic).

Remarks

Grid-based geographic transformations use a series of data files in order to transform data from one datum to another (other transformations use entirely mathematical models). These grid transformation data files are installed as part of an ArcGIS Explorer expansion pack. If the expansion pack is present on the machine, then the additional grid-based transformations will be available for use programmatically and in the user interface.

Note that geographic transformations are stored in the .nmf document file. If a machine which does not have the expansion pack installed opens an .nmf file which includes grid-based transformations, the .nmf file will load but the transformations will be ignored, therefore data may have increased alignment issues if reprojected. The transformation information remains in the .nmf file however.
