How to view the data via the web mapping portal?

The web mapping portal provides easy and quick access to data from the scientific program. 

The web mapping portal is currently only available in French. An English version is under consideration.

Step 1 : Access to the web mapping portal

Access to the portal is through the URL: https://geosas.fr/selune/

The map portal is accessible under most web browsers, although Firefox, Chrome and Edge are recommended.

If you would like more information about the portal and the data sets presented, an information pop-up window (documentation page), just click on the «i» button at the top right of the portal. It presents various tabs providing information on the information system: « BIENVENUE » (explanatory text), « LE PROGRAMME » (some key figures), « AIDE » (what to do if you get lost on the application), « DONNEES » (dataset update information) et  « VERSIONS » (information on portal updates). This window closes easily via the «X» button in the upper right or the «Fermer la fenêtre» button at the bottom.

The main web mapping portal page is a base map with:

Step 2 : Change the data displayed by default (column menu)

The main map is based on a background map and dataset loaded by default.

Change the background map

It is possible to change the background map to choose among those presented: Openstreetmap, IGN map, historical maps, old or recent aerial photographs, etc. For this, simply use the button provided for this purpose at the bottom right of the map, allowing the choice of a cartographic background:

Change the data displayed by default

The two "menu" and "legend" columns located on the left of the screen allow you to modify the default display (add/remove/configure) of the data.

Step 3 : Add and configure the data you wish to view

To add a data, simply find it among the datasets available in the leftmost menu bar, then add it. The screenshot below shows how to find the dataset in the menu, display it and modify the information filtered and displayed on the map (by default, when a filter on the time session is proposed, the choice displayed by default is always the most recent).

NB: the possible settings are as follows:

• the opacity of the data layer.
• the display mode of the layer (if proposed) named "Analysis" in the legend.
• the filter on a specific information of the dataset (if a filter is proposed) such as: temporality, etc.

It is also possible to change the order in which the data layers are displayed (which can be important if one of the datasets relates to surfaces whereas others relate to points) by moving the legend block up or down in the order of the legends (drag and drop the pictogram in front of the data name).

Step 4 : Consult data

It is possible to consult certain data sets directly on the map portal, whether they consist of polygons or points. Most datasets are searchable by a simple click on an element of the dataset.

Step 5 : Remove a dataset from the map

To remove data sets that you don't need (loaded by default or displayed by mistake and that you don't want to see), simply use the ‘X’ to delete the various captions associated with the data to be removed.

Step 6 : Export or share the map

Once your map is ready and allows you to view the data you want, you can export and/or share your map using the buttons to the right of the map background:

• Share map: a window with a link and a QR code appears. Just copy the link or QR code to share it.
• Export map: The map automatically downloads in image format (.png)
• Fullscreen mode display : the portal is displayed in full screen mode
