Helgoland Client


The Helgoland client is a thin client developed by 52North and customised for EFAS allowing the display of Observational and Forecast data on a OpenStreetMap background.

The image below is the main display of the helgoland client.

Stations that provide Realtime data area available to select.

On the Right hand side there are 2 different 'Phenomena'  available to select, averageDischargeOverPrevious6Hours and averageDischargeOverPrevious24Hours.





Users can select the parent sensor (dwd, eud, eue, cos, mcp_obs and mcp_sim).

In the image below you can see selecting all COS child models for one station for one run of the EFAS Forecast.


Users can then select the Date's available of the data in the database.

Users can then select the Child Sensor (mcp_simq1 - mcp_simq99)

In the image below I have selected multiple result times from September 1st to 3rd of the DWD Forecast and one result of the EUD forecast for comparison on one station.
