Pseudo-colour images of the seabed of the reef areas of the Eparses Islands (2009-2010) — Project Piot and IoT
Description
These images of the seabed come from the correction of the water column on hyperspectral data acquired in 2009 and 2010 for the Litto3D Indian Ocean project (IGN/SHOM) and with funding from the Agency for Marine Protected Areas (AAMP). The calculation methods are based on developments initiated within the framework of the quadripartite cooperation agreement on the “Reef Artography of the French Islands of the Indian Ocean to Part of Hyperspectral Data” between the Prefecture of Réunion, the French Southern and Antarctic Lands, the AAMP and Ifremer.
The 2019 and 2020 processing of these images as part of the Piot and IoT (pilot) project for Indian Ocean sea Turtles generated a coloured composition Red/Green/Bleu as it would be after theoretical removal of the water column.
On Glorieuses, these treatments resume the work initiated in the framework of the COPRA project on the mapping of grass trees in Thalassodendron (AFB/Marex).
The Piot project is co-financed by the Iles Éparses Consortium2017-2020, Ifremer (carrier) and its partners (CNRS-LIRMM, Kelonia and CEDTM).
The IoT project is co-financed by the ERDF-INTERREG V OI, the State, Ifremer (carrier) and its partners (CNRS-LIRMM, French Southern Lands and Antartiques, Departmental Council of Mayotte, Marin Natural Park of Mayotte, Oulanga Na Nyamba Association of Mayotte and Seychelles Islands Foundation).
