The DataSourcesNetCDF library contains objects used for accessing netCDF files and for creating rasters, features, or tables from netCDF variables in ArcGIS.

The main objects in this library are: NetCDFWorkspaceFactory, NetCDFWorkspace, NetCDFFeatureClassName, NetCDFTableName, NetCDFRasterDatasetName, NetCDFFeatureClass, NetCDFTable, NetCDFRasterDataset, and NetCDFRasterBand.

NetCDFWorkspaceFactory and NetCDFWorkspace

To work with a netCDF file, you need to create a workspace factory using the NetCDFWorkspaceFactory class. After creating a new instance of the NetCDFWorkspaceFactory object, use the OpenFromFile method to get a NetCDFWorkspace object that is used to work with the data.

You can also create a WorkspaceName and set its WorkspaceFactoryProgID and PathName to a netCDF file.

Dim pWSName As IWorkspaceName
Set pWSName = New WorkspaceName
pWSName.WorkspaceFactoryProgID = "esriDataSourcesNetCDF.NetCDFWorkspaceFactory"
pWSName.PathName = sNetCDFFile

NetCDFFeatureClassName

NetCDFFeatureClassName extends DatasetName. You can get a NetCDFFeatureClass instance by calling the Open method on any NetCDFFeatureClassName instance.

You can use the properties of the IMDFeatureClassView interface to specify the parameters required to create a netCDF feature class from a netCDF file.

Dim pVariables As IStringArray
Set pVariables = New StrArray
pVariables.Add “elevation”

Dim pRowDimensions As IStringArray
Set pRowDimensions = New StrArray
pRowDimensions.Add “station”

Dim pMDFCView As IMDFeatureClassView
Set pMDFCView = New NetCDFFeatureClassName
pMDFCView.VariableList = pVariables
pMDFCView.XDimension = “longitude”
pMDFCView.YDimension = “latitude”
pMDFCView.RowDimensionList = pRowDimensions

NetCDFTableName

The NetCDFTableName object extends DatasetName. You can get a NetCDFTable instance by calling the Open method on any NetCDFTableName instance.

You can use the properties of the IMDTableView interface to specify the parameters required to create a netCDF table view from a netCDF file.

Dim pVariables As IStringArray
Set pVariables = New StrArray
pVariables.Add “elevation”

Dim pRowDimensions As IStringArray
Set pRowDimensions = New StrArray
pRowDimensions.Add “station”

Dim pMDTableView As IMDTableView
Set pMDTableView = New NetCDFTableName
pMDTableView.VariableList = pVariables
pMDTableView.DimensionList = pDimensions

NetCDFRasterDatasetName

NetCDFRasterDatasetName extends DatasetName. You can get a NetCDFRasterDataset instance by calling the Open method on any NetCDFRasterName instance.

You can use the properties of the IMDRasterDatasetView interface to specify the parameters required to create a netCDF raster dataset from a netCDF file.

Dim pMDRDSView As IMDRasterDatasetView
Set pMDRDSView = New NetCDFRasterDatasetName
pMDRDSView.Variable = “elevation”
pMDRDSView.XDimension = “longitude”
pMDRDSView.YDimension = “latitude”

NetCDFFeatureClass

The NetCDFFeatureClass object is inherited from the FeatureClass object. It implements IFeatureClass, ITable and other interfaces.

You can use IName::Open method to create a NetCDFFeatureClass from the NetCDFFeatureClassName object. You can then use the NetCDFFeatureClass for analysis or to create a feature layer.

NetCDFTable

The NetCDFTable object extends Table. It implements IDataset, ITable and other interfaces.

You can use the IName::Open method to create a NetCDFTable from the NetCDFtableName object. You can then use the NetCDFTable for analysis or to create a table view.

NetCDFRasterDataset

The NetCDFRasterDataset object is inherited from the RasterDataset object. It implements IRasterDataset, IRasterBandCollection and other interfaces.

You can use the IName::Open method to create a NetCDFRasterDataset from the NetCDFRasterDatasetName object. You can then use the NetCDFRasterDataset for analysis or to create a raster layer.

NetCDFRasterBand

The NetCDFRasterBand object extends RasterBand. It implements INetCDFrasterBand, IRasterBand, IRasterDataset, IRasterBandCollection and other interfaces.
