TEKNIKAL 14 Buletin Geospatial Sektor Awam Introduction The Potential of Geospatial Technique in Mapping the Uncharted Reefs in Malaysia Abstract Coral reefs in Malaysia are vital ecosystems that support marine biodiversity, protect coastlines, and contribute to local economies. However, many reefs remain uncharted due to the logistical and technological challenges of traditional mapping methods. This study explores the application of advanced geospatial techniques for mapping uncharted coral reefs in Malaysia, focusing on the Pahang coastal region. The integration of satellite imagery, Geographic Information System (GIS), and underwater photogrammetry enhances the resolution and scope of mapping e orts. This research highlights the potential of geospatial techniques to revolutionise reef exploration and conservation in Malaysia, promoting sustainable management of marine resources. “ “ By dissipating wave energy, coral reefs help protect coastal communities from flooding and property damage, thus safeguarding human lives and infrastructure. MUHAMMAD FAIZ MOHD HANAPIAH Advanced Coastal Research and Innovation, Kulliyyah of Science, International Islamic University Malaysia faizhanapiah@iium.edu.my Coral reefs, often referred to as the "rainforests of the sea," are among the most vital marine habitats. Despite covering only 1% of the ocean floor, they support approximately 25% of all marine life, making them one of the most biodiverse ecosystems on the planet. This remarkable biodiversity is crucial for the health and stability of marine environments, as coral reefs provide habitat, food, and breeding grounds for a wide variety of marine species, including fish, invertebrates, and algae. The importance of coral reefs extends beyond their ecological value. They play a critical role in coastal protection, acting as natural barriers that reduce the impact of waves, storms, and erosion on shorelines. By dissipating wave energy, coral reefs help protect coastal communities from flooding and property damage, thus safeguarding human lives and infrastructure. This protective function is particularly vital in regions prone to hurricanes, typhoons, and other severe weather events. Figure 1 Nearshore reef exploration in Pahang coastal waters since 2020
