Add a panel in the GUI with a map and metadata
It might be a good idea to add a tab in the GUI in order to present the station location and metadata information (including a summary of hydroclimatic data).
It would be possible to add a dynamic map (leaflet type), but this potentially requires different coordinate systems or different geographic layer formats to be managed as input.
Another disadvantage of this solution is that it is then very complicated to include metadata, which is much more informative than a simple location.
Moreover, it increases the number of dependencies (at least the
leaflet packages) and thus the possible maintenance problems of the airGRteaching package.
A simple possibility would be to display the summary sheets of the French stations from the Banque Hydro. This severely restricts the number of stations for which the information becomes available. See the attachments for a visual overview of this choice.
