Sets Dynamically determines the forecast length or the start time of the run based on timeseries input |
Function: | Sets the forecast length or the start of the run |
|---|
Module Name: | ForecastLengthEstimator |
|---|---|
Where to Use? | In a workflow |
Why to Use? | To set the length of a forecast or the start of the forecast based on (external) timeseries. |
Description: | The forecastLengthEstimator is a module that can be used at the start of a workflow the set the length of the operations in the other modules in that workflow. |
Preconditions: | the endoverrulable attribute in the relative view period in the time series sets must be set to true in all modules you want to apply the forecast length to |

findLatestCommonExternalForecastTime
When your forecast depends on multiple external forecasts (e.g. of an NWP forecast and a Hydro forecast) you may want to harmonize that external forecast time. This can be done by identifying the common external forecast time in the ForecastLengthEstimator and using that as a identifier in the timeseriesset used in the workflow.
