This study explores the application of geospatial analysis for the sustainable development of ecotourism in the Andaman Islands. Utilizing the capabilities of Google Earth Engine (GEE), we mapped the reef habitats and geomorphic zonations around Teti'aroa Atoll, French Polynesia, as a model for similar environments in the Andaman Islands. The study employs the ACA Reef Habitat dataset (v2.0) to identify and classify reef extents, geomorphic zonations, and benthic habitats. These classifications are crucial for the conservation and promotion of marine biodiversity, which is a cornerstone of ecotourism. The visualizations are integrated into an interactive map, offering a comprehensive view of the underwater landscape. The resulting maps are exported for further analysis and potential use in planning ecotourism activities that align with environmental conservation goals. This research demonstrates the potential of cloud-based geospatial tools in enhancing ecotourism and environmental stewardship in marine environments.
