Geographic data and online maps from GRET's Rhyvière project in Madagascar - parent sheet

From 2015 to 2022, in partnership with Cite, Enea Consulting and the Institut de Recherche pour le Développement (IRD), GRET implemented the Rhyvière II project in Madagascar, which enabled at least 50,000 people in 8 communes to benefit from access to electricity, thanks to the construction of hydroelectric power plants and the implementation of decentralized electricity solutions adapted to villages far from the grid.


Throughout the project, GRET carried out studies that involved the creation of geographical data on the two areas benefiting from the project, around the communes of Bealanana (Majunga province, northern Madagascar) and Sahatona (northeastern part of the Haute Matsiatra region).


GRET partnered with Les Libres Géographes to enhance the value of these data, with the following actions:

- integration of the project's historical data into a PostGIS database

- creation of OGC flows and styles in GeoServer and metadata in GeoNetwork for each data layer

- OpenStreetMap mapping of the Bealanana and Sahatona areas and creation of thematic geographic layers updated daily via imposm

- creation of MapStore maps for each of the two zones, integrating all thematic geographic data.


These actions were carried out with members of the OpenStreetMap Madagascar community, and were the subject of training sessions designed to empower GRET Madagascar team members in the use of these techniques and products.


This parent metadata sheet provides access to all the resources available on the project: GRET web pages and reports, thematic maps and geographic data (for online viewing or downloading).
