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.
 
The recommended way to access NetCDF content is via Geoprocessing's Multidimension Tools toolbox.

See the following sections for more information about this namespace:

NetCDFWorkspaceFactory and NetCDFWorkspace
To work with a NetCDF file, 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. See the following illustration:
You can also create a WorkspaceName and set its WorkspaceFactoryProgID and PathName to a NetCDF file. See the following code example:
[Java] 
//Create a WorkspaceName. 
WorkspaceName wsName = new WorkspaceName();
wsName.setWorkspaceFactoryProgID("esriDataSourcesNetCDF.NetCDFWorkspaceFactory");
wsName.setPathName("E:/GisData/crwr.nc");

NetCDFFeatureClassName
NetCDFFeatureClassName extends DatasetName. You can get a NetCDFFeatureClass instance by calling the open method on any NetCDFFeatureClassName instance. See the following illustration:
NetCDFFeatureclass implements IMDFeatureClassView. You can use the properties of the IMDFeatureClassView interface to specify the parameters required to create a NetCDF feature class from a NetCDF file. See the following code example:
[Java] 
StrArray netCdfVariables = new StrArray();
netCdfVariables.add("elevation");

StrArray netCdfRowDimensions = new StrArray();
netCdfRowDimensions.add("lon");
netCdfRowDimensions.add("lat");

NetCDFFeatureClassName mdfcView = new NetCDFFeatureClassName();
mdfcView.setVariableList(netCdfVariables);
mdfcView.setXDimension("lon");
mdfcView.setYDimension("lat");
mdfcView.setRowDimensionList(netCdfRowDimensions);

NetCDFTableName
The NetCDFTableName object extends DatasetName. You can get a NetCDFTable instance by calling the open method on any NetCDFTableName instance. See the following illustration:
NetCDFTable implements IMDTableView. You can use the properties of the IMDTableView interface to specify the parameters required to create a NetCDF table view from a NetCDF file. See the following code example:
[Java] 
StrArray netCdfVariables = new StrArray();
netCdfVariables.add("elevation");

StrArray netCdfDimensions = new StrArray();
netCdfDimensions.add("lon");
netCdfDimensions.add("lat");

NetCDFTableName mdtView = new NetCDFTableName();
mdtView.setVariableList(netCdfVariables);
mdtView.setDimensionList(netCdfRowDimensions);

NetCDFRasterDatasetName
NetCDFRasterDatasetName extends DatasetName. You can get a NetCDFRasterDataset instance by calling the open method on any NetCDFRasterName instance. See the following illustration:
NetCDFRasterDataset implements IMDRasterDatasetView. You can use the properties of the IMDRasterDatasetView interface to specify the parameters required to create a NetCDF raster dataset from a NetCDF file. See the following code example:
[Java] 
//Specify the NetCDF raster dataset parameters
// using methods from the IMDRasterDatasetView interface.
NetCDFRasterDatasetName mdrdsView = new NetCDFRasterDatasetName();
mdrdsView.setVariable("elevation");
mdrdsView.setXDimension("lon");
mdrdsView.setYDimension("lat");

NetCDFFeatureClass
NetCDFFeatureClass extends FeatureClass. It implements IFeatureClass, ITable, and other interfaces.
You can use IName's open method to create a NetCDFFeatureClass from the NetCDFFeatureClassName object. You can then use the NetCDFFeatureClass for analysis or to create a feature layer. See the following illustration:

NetCDFTable
The NetCDFTable object extends Table. It implements IDataset, ITable, and other interfaces.
You can use the IName's open method to create a NetCDFTable from the NetCDFtableName object. You can then use the NetCDFTable for analysis or to create a table view. See the following illustration:

NetCDFRasterDataset
NetCDFRasterDataset extends RasterDataset. It implements IRasterDataset, IRasterBandCollection, and other interfaces.
You can use the IName's open method to create a NetCDFRasterDataset from the NetCDFRasterDatasetName object. You can then use the NetCDFRasterDataset for analysis or to create a raster layer. See the following illustration:

NetCDFRasterBand
The NetCDFRasterBand object extends RasterBand. It implements INetCDFRasterBand, IRasterBand, IRasterDataset, IRasterBandCollection, and other interfaces. See the following illustration:
