All available layers reported by the GetCapabilities will be available in a dropdown list. For some layers it is also possible to search for older forecasts. They are not reported by default by the GetCapabilites but requires an explicit search. This can be done by specifiying a forecast period and selecting how many forecast should be searched for during that period. When clicking the play button next to the forecast period, all available forecast times will be available in the drop down list next to the selected layer. To display a specific forecast, the forecast time can be selected from the drop down list.
Archive integration
In case an archive is connected to the FewsWebServices, it is also possible to retrieve data from the archive. Enable the Archive integration checkbox to try to get grid data from the archive if not found in the Delft-FEWS database.
Ensembles
Using the WMS Test page an extra dropdown list will appear below the Selected layer. In this example layer CS3-ens is an ensemble grid. The ensembleId is "MOSurge". When selected, the list of ensemble member id's will be populated next to it which allows you to select a specific ensemble member on the test page. When right clicking on a specific grid cell, the timeseries can be requested for a specific grid cell for the selected layer, external forecast time, ensemble and time step.
