SpatialReferenceEnvironment CoClass

Creates various spatial reference objects.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Description

SpatialReferenceEnvironment is a singleton object. However, if you are working in a multi-threaded environment, each thread will have its own SpatialReferenceEnvironment. You should not pass information between the threads.

Supported Platforms

Windows, Solaris, Linux

Extended Error Information

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.
