A study of mangroves distribution was conducted in Banggi Island using remote sensing applications and field observations. Total of 57 locations were selected as ground survey stations and observations data were applied to unsupervised and supervised SPOT 5 image. The study aims to map and quantify total area of mangroves cover at different part of Banggi Island. Result show that the mangroves in Banggi can be discriminated into 2 different groups which several mangroves genus assimilated in the same group. Effects of overlapped reflectance between each genus were minimized with additional spectral reflectance data of each genus. Each genus show significant spectral reflectance and determined as its specific spectral signature with total 87 individual leaves sampling. Global Positioning System (GPS) radius errors for each station were analyzed using distance analysis for validating the field data. The initials accuracy of unsupervised image was 10.08% and improved to 100.00% after supervised classification and ground survey data were applied in term of genus grouping
