The WIWB Import connects to the Hydronet WIWB API and has support for downloading observations and forecasts for both scalar and grid data. WIWB has a concept of DataSources which have to be configured as a property of the import. Using the meta data api of of the WIWB API the type of data is determined and processed accordingly. The import feature is available since December 2018, from Delft-FEWS version 2016.02 onwards.

WIWB is the Dutch national database for storage and dissemination of weather related data, specifically for the Dutch water sector. It has been developed in 2017 by HydroLogic, HKV and HydroConsult for Het Waterschapshuis, a national body that represents all Dutch water boards. The WIWB database is based on the HydroNET platform (www.hydronet.com) and offers a REST API for retrieving data and metadata. WIWB contains weather observations and forecasts, based on weather stations, meteorological radar data and numerical weather models. WIWB is intended for professional use only by Dutch water boards. It is not intended for public or commercial use. Only officials from Dutch water boards can request access to the WIWB API. More information on specifications and use of the WIWB API can be requested from the WWIB helpdesk (helpdesk@hydrologic.com) or in the attached document (V5.0)the Technische Instructies WIWB API.pdf. |

Access to the WIWIB API is limited to the regional water authorities in the Netherlands and can be requested from the Waterschapshuis Water (HWH) by sending an e-mail to Arnaud MensenWouter Bakker. Please list the following items in your e-mail
HWH will forward the required information to the WIWB back-office operated by HydroLogic. Your account will be configured within 5 days after the request was received by the WIWB back office. More info about WIWB at HWH can be found here. Technical instructions about the WIWB API can be found in the attached document (V5.0) Technische Instructies WIWB API.pdf. |

Access to the WIWIB API is done using a secure HTTPS connection. If a FEWS configuration is used with a client.truststore it may be required (for FEWS versions older than 2018.02) to import the latest public certificate of the WIWB service into the existing client.truststore. For more information on configuring secure HTTPS connection with a client.truststore, see How to configure secure https connection to Matroos |

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.
