Exporting to NetCDF

The NetCDF tab of the Export Data window exports the selected dataset to a NetCDF format file, specifically an NDS file. Note that Windographer does not yet import NetCDF files.

Tip: The NetCDF tab is currently available only to the customer that helped fund its development.

NetCDF Export via Command-Line Interface

You can export NetCDF files from Windographer using the following command line:

Windographer.exe -open “C:/Path/Mast1.windog” -exportnds “C:/Path/Mast1.nc4”

If the .windog file contains multiple datasets, then the above command will export only the first dataset. The optional command line switch 'alldatasetsnumeric' instructs Windographer to export each dataset to its own NetCDF file using a fixed naming convention. If ‘Workbook.windog’ contains three datasets, for example, then the following command:

Windographer.exe -open “C:/Path/Workbook.windog” -exportnds “C:/Path/Workbook.nc4” -alldatasetsnumeric

will result in the export of the following three files:

C:/Path/Workbook_001.nc4
C:/Path/Workbook_002.nc4
C:/Path/Workbook_003.nc4

Another optional command line switch 'schema' instructs Windographer to export a specific file schema. The following command will export an ‘NDS1’ schema file, for example:

Windographer.exe -open “C:/Path/File.windog” -exportnds “C:/Path/File.nc4” -schema “NDS1.0”

If the command line does not specify the schema, Windographer will export the latest schema.

Return Value

Upon completion of the command, Windographer.exe will return 0 in the case of success, or one of the error codes shown in the table below in the case of failure.

Error Code	Meaning
ERROR_NETCDF_EXPORT_WINDOG_INPUT_FILE_REQUIRED	The input file is not a windog file.
ERROR_NETCDF_EXPORT_FAILED_TO_OPEN_INPUT_FILE	Windographer failed to open the specified windog file. Check that the file exists and opens in Windographer.
ERROR_NETCDF_EXPORT_NO_DATASETS_FOUND	Windographer successfully opened the windog file, but it contained no datasets to export.
ERROR_NETCDF_EXPORT_OUTPUT_NOT_SET	The command line did not specify a valid output file name.
ERROR_NETCDF_EXPORT_IO_RESULT_FAILURE	Windographer could not export to the specified output file. The folder may not exists, you might lack write/create permissions in that folder, or the output file may be locked by another application.
ERROR_NETCDF_EXPORT_UNKNOWN	An unspecified error occurred.
