Context
The WEkEO Light 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 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 different features of the Light Viewer! 💪
Set of variables
As explained in the context, variable have been preselected to be displayed on the map, in order to visualize key variable among Earth Observation data.
On the left side of the interface, users can find a list of layers grouped by four Copernicus Services (Marine, Land, Atmosphere, Climate Change), as well as Sentinel:
Service | Variables |
Marine |
|
Land |
|
Atmosphere |
|
Climate Change |
|
Sentinel |
|
Clicking on a layer will display it on the map and clicking on the door icon will navigate to the full viewer catalogue with filters related to this layer.
Viewer customization
The Light 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 color map can be changed too
Marine layers: the appearance can be further configured by setting the
minimum and maximum values for the color map

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):
