Change the appearance of a data layer

In the layer information box you can manipulate the layer in a number of ways:

  • Change the opacity of the layer with the opacity slider

  • Make the layer visible or invisible with the “eye” toggle

  • Connect a layer to another layer with the “shackle” toggle. This allows you to change the displayed time for all connected layers at once.

  • Delete a layer with the “trash can” button

  • Change the data legend to the desired range by sliding the legend endpoints

Creating single point time-series graphs on the fly

Click on a valid data point on the map to get the exact longitude, latitude, and product value. It is then possible to create a time series for this point. After selecting to draw the time series, the drawing starts between the selected start and end date, and percentage of completion as well as the estimated time remaining is displayed.

Displaying Key performance indicators

After selecting to show the dashboard, KPIs are shown for the selected date. Moreover, the time series corresponding to the ROI is also drawn.

The time series for the ROI is drawn as well as the centered moving average +/- 20 days for this ROI (smoothed signal) available until the last 20 days, and the climatology built from the same +/-20 days smoothed signal.

The following KPI’s are currently shown for the selected date:

Data quality (%):

Represents the percentage of data usable for the ROI

Observation Volumetric (m3/m3):

Represents the current daily observation

Relative to Climatology (m3/m3):

Represents the difference between the selected date value and the climatology value at the same day of the year

Relative Change (m3/m3):

Represents the variation compared to the last observation.

Manage API requests

Specific time series request can be made clicking on the New request button in the time series window. A popup to set the parameters of the request will show up. Afterwards you can check the status of the request and retrieve the information through the API Access menu on the right, shown when clicking the API access button.

Managing regions of interest

The region of interest (ROI) menu can be found on the top right of the screen, just below the settings menu (where you can change the base layer from satellite to terrain, openstreetmap, etc.).

Region of interest

Figure showing the main components of the Planetary Variables viewer including the ROI menu at the top right

All defined ROIs are displayed in this menu. You have the option to show a specific one, or hide/show all of them. To create a new ROI, you can either draw one manually or upload a shapefile (GeoJSON format or zip archive containing the required files).

Region of interest

Once uploaded, the new ROI can be customised with a name and a description. Please note that for multipolygon shapefiles (ie multiple shapes in a file), you have the option to select a subset of them and/or to consider them as different ROI or a single one as the union of those multiple shapes.

Region of interest

Figure showing the edit/upload menu for ROI’s in the Planetary Variables viewer

Once a new ROI is created, the map is centered over this ROI and the current selected layer is shown.

Please note that when a new ROI is for the first time added (drawn or uploaded), it takes a few hours to initialize the complete historical dataset corresponding to this ROI and update the dashboard time series and KPI values.

Using labels to tag and filter ROIs

The regions of interest can be tagged using labels which you can create and customize. Those labels can then be used with the ROI search for filtering purposes.

Measure distances on the map

Clicking the arrow control on the left enables the measurement tool controls.

  • Adding points: single click. (to measure the distance between them. The total distance accumulated is shown in the last point).

  • Stop measuring: double click, escape key, or click again the arrow control on the left.

  • Clear current measurements shown: click the [x] right under the arrow control on the left.

  • Change measure unit: click the third control with a letter under the arrow control on the left. Units available: meters (m), miles (mi), nautical miles (nm).

A point can be moved once its placed via drag and drop or “picking it up” with a single click, then place it again with a another single click. A point can be removed via clicking on it while pressing the shift key. A measurement can be continued via clicking on the last point while pressing the ctrl key.

Once the measurement tool is disabled, the data will be kept on the map. But enabling it again will clear them.


The measurement tool will always take the shortest line from one point to the next.
