Abstract

Coral reefs is are an important community in coastal and marine ecosystems. Currently, they are under high environmental pressures and suffer damages from human activities and increased sea surface temperature, narrowing the live coral cover. This study aimed to assess the mapping accuracy of the live and dead coral covers using PlanetScope satellite images around Mandangin Island, Madura, Indonesia. Minimum Noise Fraction (MNF) was applied to the bands corrected for the effect of energy attenuation by the water column using the Depth Invariant Bottom Index method, and Random Forest (RF) algorithm was used for mapping. The classification results showed five classes of benthic habitat 2021, namely live coral, dead coral, rubble, seagrass, and sand. Using the confusion matrix, it was found that the live and dead coral cover models had 72.5% accuracy. The mean live coral and dead coral covers were 18.87% and 36.40%, respectively.
