Examples with NetcdfDataset ucar.nc2.dataset.NetcdfDataset used on opensource projects

Example 1 with NetcdfDataset

use of ucar.nc2.dataset.NetcdfDataset in project sis by apache.

the class DecoderWrapper method getDiscreteSampling.

 * @return {@inheritDoc}
 * @throws IOException if an I/O operation was necessary but failed.
 * @throws DataStoreException if the library of geometric objects is not available.

Example 3 with NetcdfDataset

use of ucar.nc2.dataset.NetcdfDataset in project sis by apache.

 * @throws DataStoreException if a logical error occurred.
