Our specific goal is to analyze the evolution coral reef habitats from images acquired over a period of twelve years. Our study area is located in the centre of the Coral Triangle, a hotspot of biodiversity in the Bunaken Island, Indonesia. In-situ data is used in a supervised classification approach to build classification models for eleven habitat types. Radiometric calibration is pairwise performed between each image in the data set and the reference one, and habitat models built on the reference image are used to classify the entire time series. Results obtained are discussed and the influential factors are put forward. specialized INDONESIE MER DE CORAIL 126 036 1-4 New York IEEE 2015 International Workshop on the Analysis of Multitemporal Remote Sensing Images, 8., Annecy (FRA), 2015/07/22-24 https://www.documentation.ird.fr/hor/fdi:010067244 10.1109/Multi-Temp.2015.7245758 978-1-4673-7119-3 [F B010067244] https://www.documentation.ird.fr/hor/fdi:010067244 https://www.documentation.ird.fr/intranet/publi/depot/2016-07-18/010067244.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2016-07-15 2023-02-22 fdi:010067244 fre
