Necessary predictions
PROTIDE uses water level, wave (swell) and current (water speed and direction) predictions around the Euro-Maas and IJgeul. The more accurate of course the better. The current version makes use of the data that is available at HMCN. There are several types of data available that vary in unit, location, accuracy and availability. PROTIDE uses data settings to categorize the predictions. Every data source (for example the combination rws_prediction, waterlevel, hoekvanholland in MATROOS) is coupled to one data setting so that PROTIDE knows what kind of data it is (for exmaple: "Water level", kilometer position 0 on the Euro-Maasgeul, standard deviation 0.2 and to be used if there aren't manual overrides, but before other sources).
The order (for example manual overrides are used first, then the predictions from rws_prediction and finally rough model results from csm8) in the calculation is determined by the data classifications. By selecting one of the classifications for a data setting, the order is set.
PROTIDE polls MATROOS every 15 minutes to check if there are new predictions available. MATROOS is an online database that is filled by HMCN periodically with new model outcomes and adjusted predictions. It is investigated if the PROTIDE can be filled with historical data to be able to do tidal window calculations in the past for analysis purposes.
