Visualize a SOS

Task: Visualize a SOS


Aim: Visualize in the Chart Viewer and Map Viewer data delivered by a SOS.


  1. Map Viewer, Chart Viewer, and Time Controller Portlets deployed on an installation of the ENVISION Portlet container and configured with a SOS.

Brief description:

In the ENVISION Platform, the user can visualize different types of resources. The data coming from Sensor Observation Service (SOS) contain both a location (which is in most of the case represented as a point) and data series representing the observation; they are represented as points drawn on the map that the user can select to display a chart of the observation.

The procedure is as follows:

  1. The map displays the points representing the location of the observations of the newly added layer; the Time Controller Portlet displays the beginning and ending date when observation are available for this layer
  2. Select new start/end date for visualization of the animation on this time dependent layer and validate the new dates by clicking on the “Validate” button
  3. To select a specific sensor, zoom in/out or pan in the map using the buttons at the top of the map (the hand, the magnifying glasses, and the earth icons)
  4. Selects the “arrow” button in the toolbar of the Map Viewer Portlet and click on a sensor – a panel opens at the right displaying some information and options
    6. Visualize a SOS
  5. Select an offering and observation to display on a chart; select the type of graph and create a new graph by clicking on the button “Create a new chart” – a new chart is created in the Chart Viewer Portlet
  6. Zoom in/out the chart to display more precise data;
  7. Select another sensor by clicking on it;
  8. On the panel “Sensor Observation”, select a property and click on “Add to chart” – another observation is displayed in the Chart Viewer Portlet.

Concrete example: Interested users can test the resource visualization. The steps are as follows:

  1. Follow the guide Configure SOS visualization
  2. Use the page created in step 1
