Global Mangrove Watch (1996 - 2016) Version 2.0

The Global Mangrove Watch (GMW) data layers were developed in a collaboration between Aberystwyth University (U.K.), solo Earth Observation (soloEO; Japan), Wetlands International the World Conservation Monitoring Centre (UNEP-WCMC) and the Japan Aerospace Exploration Agency (JAXA). The aim was to provide geospatial information about mangrove extent and changes to the Ramsar Convention, national wetland practitioners, decision makers and NGOs. It is part of the Ramsar Science and Technical Review Panel (STRP) work plan for 2016-2018 and a Pilot Project to the Ramsar Global Wetlands Observation System (GWOS), which is implemented under the GEO-Wetlands Initiative. The primary objective has been to provide countries lacking a national mangrove monitoring system with first cut mangrove extent and change maps, to help safeguard against further mangrove forest loss and degradation. The GMW has generated a global baseline map of mangroves for 2010 using ALOS PALSAR and Landsat (optical) data, and changes from this baseline for seven epochs between 1996 and 2016 derived from JERS-1, ALOS and ALOS-2.

全球红树林观测（Global Mangrove Watch，GMW）数据集图层由英国阿伯里斯特威斯大学、日本独立地球观测机构solo Earth Observation（soloEO）、国际湿地组织与联合国环境规划署世界保护监测中心（UNEP-WCMC）以及日本宇宙航空研究开发机构（Japan Aerospace Exploration Agency，JAXA）联合开发。本数据集旨在为《拉姆萨尔公约》（Ramsar Convention）、各国湿地从业者、政策制定者及非政府组织提供红树林分布范围与动态变化的地理空间信息。该项目属于2016-2018年拉姆萨尔科学与技术审查小组（Science and Technical Review Panel，STRP）工作计划的组成部分，同时也是依托《地球观测组织湿地倡议》（GEO-Wetlands Initiative）实施的拉姆萨尔全球湿地观测系统（Global Wetlands Observation System，GWOS）试点项目。其核心目标是为缺乏国家级红树林监测体系的国家提供首版红树林分布与变化制图成果，以助力遏制红树林的进一步流失与生态退化。全球红树林观测项目已利用ALOS PALSAR与Landsat（光学）遥感数据生成了2010年全球红树林基线分布图，并基于JERS-1、ALOS及ALOS-2遥感数据，生成了1996年至2016年间7个时间节点相较于该基线的红树林变化数据。
