汤加于2026年完成了国家LiDAR地图绘制工作,以通过具有气候抗御力的规划来遏制海平面上升。 Tonga completes national LiDAR mapping in 2026 to fight sea-level rise with climate-resilient planning.

2026年,汤加将通过由绿色气候基金资助、开发计划署领导、太平洋共同体和汤加政府支助的汤加沿海复原力项目,全面覆盖其低洼岛屿的LIDAR。 In 2026, Tonga will complete full national LiDAR coverage of its low-lying islands through the Tonga Coastal Resilience Project, funded by the Green Climate Fund and led by UNDP with support from the Pacific Community and Tonga’s government. 该项目利用福格罗的高级空中勘测,将建立一个统一、高精确度的3D高海拔基线,方法是整合以往勘察的数据,提高国家模拟海平面上升、评估洪水风险和指导抵御气候变化基础设施规划的能力。 The project, using advanced aerial surveys by Fugro, will create a unified, high-accuracy 3D elevation baseline by integrating data from previous surveys, enhancing the nation’s ability to model sea-level rise, assess flood risks, and guide climate-resilient infrastructure planning. 能力建设工作将加强地理空间数据使用方面的当地专门知识,支持基于证据的长期适应战略。 Capacity-building efforts will strengthen local expertise in geospatial data use, supporting long-term, evidence-based adaptation strategies.
