NTv2Transformation Class (ArcObjects .NET 10.8 SDK)
|
This document is archived and information here might be outdated. Recommended version. |
Creates a NTv2-based transformation.
The NTv2Transformation method converts between two geographic coordinate systems (datums) using a file. The method was created by the Geodetics Division of Natural Resources Canada and has since been used by several other countries including Australia, New Zealand, and Germany. The file format is documented online and a script exists that can convert information stored in a shapefile to an NTv2-format file. See http://arcscripts.esri.com/details.asp?dbid=13654
Use the ISupportErrorInfo method InterfaceSupportsErrorInfo to determine if the object supports extended error information. If the object supports extended error info, VC++ developers should use the OLE/COM IErrorInfo interface to access the ErrorInfo object. Visual Basic developers should use the global error object Err to retrieve this extended error information.
