Package ucar.nc2.dt.grid

Class GridDataset

  • All Implemented Interfaces:
    Closeable, AutoCloseable, GridDataset, FeatureDataset, FileCacheable
    public class GridDataset
extends Object
implements GridDataset, FeatureDataset
    Make a NetcdfDataset into a collection of GeoGrids with Georeferencing coordinate systems.

    A variable will be made into a GeoGrid if it has a Georeferencing coordinate system, using GridCoordSys.isGridCoordSys(), and it has no extra dimensions, ie GridCoordSys.isComplete( var) is true. If it has multiple Georeferencing coordinate systems, any one that is a product set will be given preference.

    Example: 

     GridDataset gridDs = GridDataset.open(uriString);
 List grids = gridDs.getGrids();
 for (int i = 0; i < grids.size(); i++) {
   GeoGrid grid = (Geogrid) grids.get(i);
 }
