Abstract:
This paper presents a framework for change detection of coral reef habitats in muti-temporal and multi-spectral satellite imagery acquired by multiple sensors. 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.
