La petite centaine d\u2019atolls coralliens polyn\u00e9siens constitue un patrimoine fragile et unique. <\/p>\n\n\n\n

Bien que relativement pr\u00e9serv\u00e9s en apparence, ces atolls subissent l\u2019impact des activit\u00e9s anthropiques (tourisme, perliculture, p\u00eache, introduction d\u2019esp\u00e8ces envahissantes, \u2026) ainsi que les cons\u00e9quences pr\u00e9visibles du r\u00e9chauffement global (cyclones plus fr\u00e9quents, mont\u00e9e des eaux).<\/p>\n\n\n\n

Leur surveillance environnementale devient n\u00e9cessaire pour organiser et optimiser leur protection.<\/p>\n\n\n\n

Avec le souhait de l’acteur Marlon Brando et le soutien de la Tetiaroa Society<\/a><\/em>, l’atoll de Tetiaroa constitue aujourd’hui un site d’\u00e9tude exceptionnel, pr\u00e9serv\u00e9 depuis une soixantaine d’ann\u00e9es. <\/p>\n\n\n\n

Les diff\u00e9rents projets en G\u00e9omatique sur Tetiaroa ont pour but de d\u00e9velopper de nouvelles techniques de cartographies adapt\u00e9es aux atolls et permettant d’en contr\u00f4ler la sant\u00e9 et d’en surveiller d’\u00e9ventuelles \u00e9volutions. <\/p>\n\n\n

Atoll de Tetiaroa Pl\u00e9iades 2014 (IDEA)<\/figcaption><\/figure>\n<\/div>\n\n\n

Le travail effectu\u00e9 sur le site d\u2019\u00e9tude de l\u2019atoll de Tetiaroa par l’UPF, avec le soutien appuy\u00e9 de la Tetiaroa Society, de la cellule topographique de la DAF de Polyn\u00e9sie fran\u00e7aise, ainsi que celui des chercheurs internationaux, a permis de constituer une banque de donn\u00e9es cartographiques unique en Polyn\u00e9sie. <\/p>\n\n\n\n

Celle ci contient, entre autres, l’int\u00e9gralit\u00e9 des donn\u00e9es satellites et prises de vues a\u00e9riennes de 1955 \u00e0 2023, une donn\u00e9e lidar exceptionnelle de 2017( ETH Zurich \/ IDEA), ainsi que de nombreuses couches vectorielles d\u00e9riv\u00e9es de ces donn\u00e9es brutes (trait de cote, occupation des sols, strates de v\u00e9g\u00e9tation), mais aussi gr\u00e2ce \u00e0 des programmes originaux (b\u00e2timents du motu Onetahi, sites arch\u00e9ologiques, toponymes, emplacement des \u00e9chantillonnages scientifiques, etc.)<\/p>\n\n\n\n

Cette banque de donn\u00e9es cartographiques fait de Tetiaroa le premier atoll de Polyn\u00e9sie fran\u00e7aise surveill\u00e9 \u00e9troitement par des techniques de g\u00e9omatique. <\/p>\n\n\n\n

L’\u00e9tude de ce site-mod\u00e8le vu par le prisme de la g\u00e9omatique en g\u00e9n\u00e9ral vise \u00e0 cr\u00e9er de nouveaux protocoles de cartographies, et de surveillance environnementale adapt\u00e9s aux atolls coralliens qui soient transposables aux atolls des Tuamotu.<\/p>\n\n\n\n
