Partners
DONIA was created and is managed by Andromède Océanologie with the support of trustfull partners.
Created by the 1964 Water Law (loi sur l’eau), l’Agence de l’eau (the French Water Agency) is a public State institution, under the supervision of the Ministry in charge of sustainable development.
Its mission is to contribute to improving water management, to fight against water pollution and to protect aquatic environments.
Independent and entirely owned by a non-profit endowment fund, NAOS is dedicated to loving, understanding, and caring for living things.
Founded in 1864, Société Générale combines financial strenght, innovation and a sustainable growth strategy.
Société Générale offers a range of products that allow investors to contribute to the DONIA app.
TECHNICAL PARTNERS
Some of the maps available in DONIA are provided by trusted partners.
The mapping data of seagrass meadows in the Greek region were provided by HCMR – Institute of Oceanography, and originate from the national dataset published in Panayotidis et al. 2022 (Botanica Marina, DOI: 10.1515/bot-2022-0011).
This dataset was developed using a combination of methods: optical remote sensing (Landsat-8 satellite imagery and Google Earth), acoustic techniques (side-scan sonar), and in situ visual survey methods (SCUBA diving, towed underwater cameras, and remotely operated vehicles), validated across approximately 400 field sites along the Greek Aegean coastline.
The spatial accuracy of the resulting polygons varies depending on the area and the method used: polygons derived from Landsat-8 correspond to a mapping scale of 1:60,000, while those derived from Google Earth imagery or side-scan sonar reach scales of 1:5,000 to 1:15,000. Each polygon in the dataset is associated with information on the method used for its production, allowing users to assess the level of spatial detail for each area.
As part of the Greek Islands Seagrass Alliance initiative, the South Aegean dataset was revised and corrected for use in the DONIA® application. Seagrass meadow boundaries are considered dynamic and subject to change over time. Users of the DONIA® application will be informed of the indicative nature of the mapped boundaries.
The mapping data of marine habitats of the Republic of Croatia were provided via the BioPortal, which serves as the public access point to the national nature protection information system.
They originate from the Marine Habitat Map of the Republic of Croatia (2023, version 1.1), developed as part of the project “Mapping of coastal and seabed habitats in waters under national jurisdiction,” co-funded by the European Union.
These data, including in particular Posidonia seagrass meadows, were produced from scientific and technical work carried out by several specialized institutions, and are made available and regularly updated via the BioPortal web services (WMS/WFS).
