Accessing raster workspaces

Accessing raster workspaces

All geodatabase workspaces support the IRasterWorkspaceEx interface, while file workspaces support IRasterWorkspace. See the following code example:

 

[C#]

//Open file geodatabase workspace as RasterWorkspace.
static IRasterWorkspaceEx OpenFGDB(string FGDBPath)
{
    //FGDBPath string example: c:\data\raster.gdb.
    IWorkspaceFactory2 workspaceFactory = new FileGDBWorkspaceFactoryClass();
    return (IRasterWorkspaceEx)workspaceFactory.OpenFromFile(FGDBPath, 0);
}

//Open ArcSDE workspace as RasterWorkspace.
static IRasterWorkspaceEx OpenSDE(string conString)
{
    //conString example: SERVER=qian;INSTANCE=9200;VERSION=sde.DEFAULT;USER=raster;PASSWORD=raster.
    IWorkspaceFactory2 workspaceFactory = new SdeWorkspaceFactoryClass();
    return (IRasterWorkspaceEx)workspaceFactory.OpenFromString(conString, 0);
}

//Open accessed workspace as RasterWorkspace.
static IRasterWorkspaceEx OpenAccess(string PGDBPath)
{
    //FGDBPath string example: c:\data\rasters.mdb.
    IWorkspaceFactory2 workspaceFactory = new AccessWorkspaceFactoryClass();
    return (IRasterWorkspaceEx)workspaceFactory.OpenFromFile(PGDBPath, 0);
}

//Open file workspace as RasterWorkspace.
static IRasterWorkspace OpenFileWorkspace(string wsPath)
{
    //wsPath example: c:\data\rasters.
    IWorkspaceFactory workspaceFact = new RasterWorkspaceFactoryClass();
    return (IRasterWorkspace)workspaceFact.OpenFromFile(wsPath, 0);
}

[VB.NET]

'Open file geodatabase workspace as RasterWorkspace.

    'FGDBPath string example: c:\data\raster.gdb.
    Dim workspaceFactory As IWorkspaceFactory2 = New FileGDBWorkspaceFactoryClass()
    Return CType(workspaceFactory.OpenFromFile(FGDBPath, 0), IRasterWorkspaceEx)
End Function

'Open ArcSDE workspace as RasterWorkspace

Public Function OpenSDE(ByVal conString As String) As IRasterWorkspaceEx
    'conString example: SERVER=qian;INSTANCE=9200;VERSION=sde.DEFAULT;USER=raster;PASSWORD=raster.
    Dim workspaceFactory As IWorkspaceFactory2 = New SdeWorkspaceFactoryClass()
    Return CType(workspaceFactory.OpenFromString(conString, 0), IRasterWorkspaceEx)
End Function

'Open accessed workspace as RasterWorkspace.

Public Function OpenAccess(ByVal PGDBPath As String) As IRasterWorkspaceEx
    'FGDBPath string example: c:\data\rasters.mdb.
    Dim workspaceFactory As IWorkspaceFactory2 = New AccessWorkspaceFactoryClass()
    Return CType(workspaceFactory.OpenFromFile(PGDBPath, 0), IRasterWorkspaceEx)
End Function

'Open file workspace as RasterWorkspace.

Public Function OpenFileWorkspace(ByVal wsPath As String) As IRasterWorkspace
    'wsPath example: c:\data\rasters.
    Dim workspaceFact As IWorkspaceFactory = New RasterWorkspaceFactoryClass()
    Return CType(workspaceFact.OpenFromFile(wsPath, 0), IRasterWorkspace)
End Function
