Developing a high-resolution elevation map for Majuro Atoll, Republic of the Marshall Islands
Report Summary
Pacific atolls are at extreme and increasing inundation risk due to changing climate and sea level rise. Due to the low flat contours of these areas, accurate high-resolution elevation data is vital for inundation modelling that supports vulnerability and adaptation planning. We have created a high-resolution topobathymetric digital elevation model (TBDEM) for the Majuro Atoll in the Republic of the Marshall Islands by integrating nine spatial data sources to ensure the best available topographic and bathymetric accuracy. This digital map will allow accurate inundation modelling and coastal vulnerability assessments for Majuro Atoll and provides a tool that resource managers and decision makers can use to increase the spatial accuracy of adaptation plans, improving community resilience as sea levels rise.
