    v40 v41  
    5454'''Related fix''': #4284 [[BR]]
    5555
    56 '''New ConfigOptions''': GDAL_NETCDF_BOTTOMUP=YES/NO, default YES, for default export and import
    57 
    58 '''New -co options''': WRITE_BOTTOMUP=YES/NO, default YES, for default export
     56'''New ConfigOptions''': GDAL_NETCDF_BOTTOMUP=YES/NO (default YES) for default export and import
     57
     58'''New -co options''': WRITE_BOTTOMUP=YES/NO (default YES) for default export
    5959
    6060'''Has back-compat impact?''': Only for GDAL versions prior to 1.6 (r18152).  Since then, a check is made to ensure the driver recognizes bottom-up grids (using the CF tags) and flips the y-axis accordingly. An exception is when there is not geo-referencing data, in which case it may be in the wrong direction.  The export options can be used to force top-down if needed.

    9090'''New -co options''':
    91   * WRITE_LONLAT=YES/NO/IF_NEEDED (default: YES for geographic, IFNEEDED for projected) ->Note, this not implemented yet
     91  * WRITE_LONLAT=YES/NO/IF_NEEDED (default: YES for geographic, IF_NEEDED for projected)
    9292  * TYPE_LONLAT=float/double (default: double for geographic, float for projected)

    112112==== 3.2) Proj. SRS Handling: Continue saving GDAL custom attribute tags in addition to CRS definition, but add option not to save ====
    113113
    114 '''New -co options''': -co WRITE_GDAL_TAGS (yes/no, defaults to yes)[[BR]]
     114'''New -co options''': -co WRITE_GDAL_TAGS=YES/NO (default: YES)[[BR]]
    115115'''Has back-compat impact?''': No

    169169  * FILETYPE=NC/NC2/NC4
    170170  * COMPRESS=NONE/DEFLATE/PACKED (default: NONE)
    171   * ZLEVEL=[1-9] (default: 1)
    172 
    173 '''Has back-compat impact?''': NC2 and NC4 filetypes, as well as DEFLATE and PACKED compression may not be supported by older netcdf installations and GDAL versions. However, these are optional therefore default behaviour causes no backwards compatibility issues.
     171  * ZLEVEL=[1-9] (default: 1) note: higher ZLEVEL values do not decrease size significantly
     172
     173'''Has back-compat impact?''': NC2 and NC4 filetypes, as well as DEFLATE and PACKED compression may not be supported by older netcdf and GDAL versions. NC4 filetype and DEFLATE compression require netcdf-4 and HDF5 and DEFLATE  requires zlib. PACKED compression has to be added to the driver for import also. However, these are optional therefore default behaviour causes no backwards compatibility issues.
