Define a layer creation option that applies to all layers. Define a global attribute that must be written (or removed) and applies to all layers. Define the characteristics of an OGR field / netCDF variable that applies to all layers (that actually uses it) Define layer specific settings for layer creaetion options, fields and attributes. Value to set as attribute, or empty string to delete an existing attribute Define an attribute that must be written (or removed) from a OGR field / netCDF variable. OGR field name. netCDF variable name. When both name and netcdf_name are set, the OGR field {name} will be written as the netCDF {netcdf_name} variable. When netcdf_name is set, but name is none, then the Field definition will match an implictly created netCDF variable, such as x/lon, y/lat, z, ... Name of the main dimension against which the variable must be indexed. If not set, the record dimension will be used. Only useful when using a layer with FeatureType!=Point. Define a layer creation option. Overrides or appended to existing global layer creation options. Define a global attribute that must be written (or removed). Overrides or appended to existing global attributes. Define the characteristics of an OGR field / netCDF variable (that must exist as an explicit OGR field, or an implicitly created netCDF variable). Supersedes global Field definition. OGR layer name. netCDF group name.
