52°North Helgoland Client

The 52°North Helgoland Client is a lightweight web application that enables the exploration, visualization and analysis of sensor web data in various fields of use, e.g. hydrology, meteorology, environmental monitoring, traffic management. This tutorial shows you how to use the Helgoland Client. In this tutorial we use as an example the 52°North SOS which was installed in the SOS Installation War File tutorial and we use the data which was added to the SOS in the SOS Example Request tutorial. But you can also follow along the tutorial with different data.

Workflow

The workflow would be:

Open Helgoland Client

The 52°North Helgoland Client is part of the 52°North SOS installation. This means that we have already successfully installed Helgoland with the SOS. You can access the Helgoland Client from the SOS menu.

When you open the Helgoland Client you come to the Diagram view. Because you opened the Helgoland Client for the first time you have no data selected to be shown in the Diagram.
