Context
The WEkEO Light Data Viewer is a new tool of the WEkEO platform, designed with simplicity in mind, making it the perfect starting point for beginners. It comes with a predefined set of commonly used variables, allowing new users to explore and visualize Earth Observation data quickly and effortlessly.
The variables are presented across three dimensions: longitude, latitude, and time. Additionally, certain layers incorporate a fourth dimension: depth.
The Light Data Viewer has an intuitive, easy-to-use interface with multiple customization functionalities allowing to fine-tune the way data is displayed on the map.
Without any further ado, let's explore the features of the Light Data Viewer! 💪
Step by step Guide
Key variables
A set of layers has been preselected to be displayed on the map, in order to visualize key variables among Earth Observation data:
On the left side of the interface, users can find a the various Copernicus Services (Marine, Land, Atmosphere, Climate Change), as well as Sentinel data.
Clicking on a layer will display it on the map and clicking on the door icon will open the catalogue in the Expert Data Viewer with filters related to this layer.
Here are the available variables in the Light Viewer:
Service | Variables |
Marine |
|
Land |
|
Atmosphere |
|
Climate Change |
|
Sentinel |

Map navigation
You can navigate around the map by clicking and holding the left mouse button, then dragging the map in any direction—left, right, up, or down.
To zoom in or out, simply use your mouse scroll wheel. If you're using a trackpad, this is equivalent to performing a two-finger scroll gesture: place two fingers on the trackpad and move them downward to zoom in or upward to zoom out.
💡WEkEO Pro Tip: one of the main functionalities of both Light and Expert Data Viewers is the zooming power on the map, which allows to reach and visualize even the highest spatial resolutions.
Map customization
The Light Data Viewer allows modifying its appearance at different levels:
Viewer settings
By clicking on the left side gear icon (1), a popup will appear allowing users to enable or disable the Basemap and Coastline & reference features:
Layer appearance
The appearance of the active layer can be changed by clicking on the gear icon (2) on the right side. A new window will appear, with options that may vary depending on the layer:
Sentinel and categorical layers: only the opacity can be modified
Other layers: the colormap can be changed as well
Marine layers: the appearance can be further configured by setting the
minimum and maximum values for the colormap

Map projection
Some layers can be visualized in polar projections. The current projection can be changed by clicking on the projection switcher (3):
If a layer cannot be displayed in the selected projection, a button will appear below the layer name. By clicking on it, the projection will switch to the correct one:
Time and Depth
Layers can be explored across their full temporal range (5) and, for Marine layers, examine variations based on ocean depth (4):
