The WIWB API has the default option that aggregation to larger timesteps is valid when at least one timestep is available. For example: a 5 minute timestep is aggregated to hourlies when at least one 5 minute timestep is available. For Delft-FEWS applications this is usually not the best solution. Therefore a so-called "minimumAggregationAvailability" option has been added. This value (of type double) has a valid range from 0 to 1 and indicates to the WIWB API the fraction of how much original timesteps should be available in the new timestep. Usually the value will be set to 1, as also can be seen from the below config example "aggregated radar products".
Authentication
By default the WIWB api is protected by a user name and password, that can be specified in the import configuration.
Since 2019.02 it is possible to specify a Bearer token. This is typically used when using OpenID Connect as authentication method. To enable a bearer token as authentication mechanism, the following property should be set:
| Code Block |
|---|
<string key="authentication" value="BearerToken" /> |
The actual bearer token should be set in the password field of the import configuration. The username is not used when using a bearer token for authentication.
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.
