IMIS - Marine Research Groups

The following actions are important in the creation of the dataset:
- installation, management and maintenance of monitoring points in the field;
- forwarding files with raw data from the individual data loggers to a central server;
- picking up the data files on the central server and performing the necessary conversions (ETL system);
- forwarding (ETL system) the converted data files to the WISKI database;
- 24*7 monitoring of ETL and WISKI database system and carrying out corrective maintenance if required;
- manual validation of measurements of the hydrological parameters waterlevel and discharge on a regular basis, based on gaugings, RTK control measurements and calibration measurements. This manual validation is done within the WISKI application, assigning a quality code to each data point. Validation includes removing outliers, filling missing data based on estimates or measurements from nearby stations, shifting data within a certain range,...;
- frequent manual validation of the precipitation data of the HIC monitoring network by the RMI;
- publication of validated data in hydrological yearbooks (discharges), multiannual overviews (tide area), ... Validated data are also available via HIC-webservices (https://hicws.vlaanderen.be)
