Class CFGridCoverageWriter2

java.lang.Object

ucar.nc2.ft2.coverage.writer.CFGridCoverageWriter2

public class CFGridCoverageWriter2
extends Object

Write CF Compliant Grid file from a Coverage. First, single coverage only. - The idea is to subset the coordsys, use that for the file's metadata. - Then subset the grid, and write out the data. Check that the grid's metadata matches.

Write a netcdf/CF file from a CoverageDataset

Parameters:

gdsOrg - the CoverageDataset

gridNames - the list of coverage names to be written, or null for all

subset - defines the requested subset, or null to include everything in gdsOrg

tryToAddLatLon2D - add 2D lat/lon coordinates, if possible

testSizeOnly - dont write, just return expected size

writer - this does the actual writing, may be null if testSizeOnly=true

Returns:

the total number of bytes that the variables in the output file occupy. This is NOT the same as the size of the the whole output file, but it's close.

Throws:

IOException

InvalidRangeException
