IRasterAnalysisGlobalEnvironment Interface

Provides access to members that control the global environment for raster analysis.

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

Introduced in ArcGIS 10 to allow for the processing of raster data in Spatial Analyst without the need to convert to ESRI grid format.

The following summarizes IRasterAnalysisGlobalEnvironment:

If IRasterAnalysisGlobalEnvironment.AvoidDataConversion is not used or is set to false, and an output name is specified via IRasterOpBase, the input data is read natively and the output data is permanent in the requested format.
If IRasterAnalysisGlobalEnvironment.AvoidDataConversion is set to true, and IRasterOpBase is not used, the data is read natively; however, the output is a temporary ESRI grid in the user-defined workspace.
If neither IRasterAnalysisGlobalEnvironment nor IRasterOpBase is used, conversion to an ESRI grid is done on the input data and the output is a temporary ESRI grid.

		Description
	AvoidDataConversion	Indicates weather to avoid data conversion in the RasterAnalysis.
