Overview

This import is available in DELFT-FEWS versions after 28-10-2009 (FEWS version 2009.02)

In DELFT-FEWS versions 2011.02 and later this import type can also be used to import data using OPeNDAP, see Import data using OPeNDAP.

Imports scalar time series data from NetCDF files which comply to the CF standard. More information about the cf standards can be found at http://cfconventions.org/cf-conventions/v1.6.0/cf-conventions.html.

For an example of the format that can be imported with this import type, see http://cfconventions.org/cf-conventions/cf-conventions.html#_orthogonal_multidimensional_array_representation_of_time_series

For details about other formats of NetCDF files that can be imported in Delft-FEWS, see NetCDF formats that can be imported in Delft-FEWS.

An example of the IdMapping used for the NETCDF-CF_TIMESERIES import will be given below.
In this example, the mapped locations correspond to the locations of the locatiesSet as defined above in the ImportNetcdf_Timeseries.xml.

Note that in the IdMapping of the parameters and locations, the external name must match the variable and location names as used by the netcdf file exactly (case sensitive).
