Enteromorpha Prolifra aerial remote sensing monitoring using array camera

In summer of 2008, an outbreak of Enteromorpha Prolifra (EP), a kind of green algae, occurred in the Yellow Sea of china and posed a serious threat to the 29th Olympic Sailing Games. A color array camera was installed on the aircraft and used to monitoring the spatial distribution of EP. In this paper, we measured the spectral properties of EP and analyzed the R, G, B three band aerial remote sensing images which contains EP, sea water and sunglint. After preprocessing of array images, a decision tree was constituted considering the analysis which can retrieval EP and eliminate the sunglint from images. The retrieval results were validated by field survey.
