How to save a mosaic dataset to a raster dataset (ArcObjects .NET 10.5 SDK)

Summary

A mosaic dataset represents a mosaic view of a collection of individual rasters. The sample provide an example if you want to save the mosaic dataset to a single raster dataset in a file format or a GDB raster.

Following example reads a mosaic dataset in a File geodatabase, and save it out to a raster dataset in the same geodatabase. you can also save it to any file format by changing the workspace and format string.

[C#]

//Open a File geodatabase workspace
IWorkspaceFactory workspaceFactory=new FileGDBWorkspaceFactoryClass();
IWorkspace wsGDB=workspaceFactory.OpenFromFile(@"c:\filegeodatabase.gdb", 0);

//Open a mosaic dataset using the MosaicWorkspaceExtensionHelper class
IMosaicWorkspaceExtensionHelper mosaicHelper=new
    MosaicWorkspaceExtensionHelperClass();
IMosaicWorkspaceExtension mosaicWs=mosaicHelper.FindExtension(wsGDB);
IMosaicDataset mosaic=mosaicWs.OpenMosaicDataset("myMosaicDataset");

//a mosaic dataset is a special type of function raster dataset
IFunctionRasterDataset functionDS=(IFunctionRasterDataset)mosaic;

//Use ISaveAs to write out a raster dataset. The size of a raster dataset can be exported from
//a mosaic is defined in the default properties of a mosaic dataset. Make sure the output size 
//is within the limit.
ISaveAs rasterSaveAs=(ISaveAs)functionDS;
rasterSaveAs.SaveAs("outRaster", wsGDB, "GDB");

[VB.NET]

'Open a File geodatabase workspace
Dim workspaceFactory As IWorkspaceFactory=New FileGDBWorkspaceFactory
Dim wsGDB As IWorkspace=workspaceFactory.OpenFromFile("c:\filegeodatabase.gdb", 0);

'Use MosaicWorkspaceExtensionHelper class to open a mosaic dataset
Dim mosaicHelper As IMosaicWorkspaceExtensionHelper=New MosaicWorkspaceExtensionHelperi
Dm mosaicWs As IMosaicWorkspaceExtension=mosaicHelper.FindExtension(wsGDB)
Dim mosaic As IMosaicDataset=mosaicWs.OpenMosaicDataset("myMosaicDataset")

'Mosaic dataset is a type of function raster dataset
Dim functionDS=CType(mosaic, IFunctionRasterDataset)

'Use ISaveAs to write out a raster dataset. The size of a raster dataset can be exported from
'a mosaic is defined in the default properties of a mosaic dataset. Make sure the output size
'is within the limit.

Dim rasterSaveAs=CType(functionDS, ISaveAs)
rasterSaveAs.SaveAs("outRaster", wsGDB, "GDB")
