public interface IRasterAnalysisGlobalEnvironment
extends Serializable

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

Description

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.

Product Availability

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

Method Summary

boolean	isAvoidDataConversion() Indicates weather to avoid data conversion in the RasterAnalysis.
void	setAvoidDataConversion(boolean bAvoid) Indicates weather to avoid data conversion in the RasterAnalysis.

Method Detail

setAvoidDataConversion

void setAvoidDataConversion(boolean bAvoid)
                            throws IOException,
                                   AutomationException

Indicates weather to avoid data conversion in the RasterAnalysis.

Remarks

Setting to false (the default setting) is the same as in versions before ArcGIS 9.4.

Setting the property to True ensures that all processing is performed natively on the raster data. This improves the overall performance as there is no need for the input data to be converted to ESRI grid format. The output data, however, is still temporary rasters in ESRI grid format.

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

Parameters:

bAvoid - The bAvoid (in)

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.
