Aggregated products
All data sources as in the table above have their original interval. If you want to import an aggregated product, the WIWB API supports that. You can aggregate every product with a multiplier of its original interval. The <timestep> configured in the Delft-FEWS import moduleInstance of that datasource will be interpreted whether you want to import the original or an aggregated product. E.g. the KNMI Radar products have an original interval of 5 minutes, so aggregation options are 10 minutes (2 x 5 minutes), 15 minutes (3 x 5 minutes) etc. As mentioned, the <timestep> definition in Delft-FEWS will be leading. Disaggregating is not supported.

The amount of data in one WIWB request (download option) also has its maximum. This maximum data request is limited to the currently installed WIWB-server (internal) memory capacity, which is 12 GB. This means that an individual data request can not exceed this size. This maximum of 12 GB is valid per data request, since all data requests are processed sequentially. If the data request is too large, the server runs out of memory and this data requests fails. Delft-FEWS reports that an error has occured at the WIWB-server side. To download the requested data, the user needs to split up the data request. A common approach would be to reduce the number of timesteps. Below, 3 examples of benchmark data requests are given. These examples stay within the current WIWB-server limits and will be successful. Please use these as inspiration for your own data requests.

Missing values
If the WIWB specifies the missing value for a datasource, this will be used by FEWS. The missing value can also be specified in the import configuration as well. The default value for missing value is -9999 for the WIWB API.
