Global Land Cover Map for 2009 (GlobCover 2009)

The GlobCover initiative of ESA developed and demonstrated a service for the generation of global land cover maps, based on Envisat MERIS Fine Resolution (300 m) mode data. ESA and Université catholique de Louvain demonstrated the possibility to use the GlobCover system operationally by delivering GlobCover 2009, the 2009 global land cover map, within a year of the last satellite acquisition. For maximum user benefit the thematic legend of GlobCover is compatible with the UN Land Cover Classification System (LCCS). The system is based on an automatic pre-processing and classification chain. Finally, the global land cover map was validated by an international group of land cover experts and the validation reports are also available to the user community.

欧洲空间局（ESA）的GlobCover项目开发并验证了一套基于恩维萨特（Envisat）卫星搭载的中等分辨率成像光谱仪（MERIS）300米精细分辨率模式数据的全球土地覆盖图生成服务。欧洲空间局与卢万天主教大学（Université catholique de Louvain）通过在末次卫星数据获取后的一年内交付2009年全球土地覆盖图GlobCover 2009，证实了GlobCover系统可实现业务化运行。为最大化用户使用效益，GlobCover的专题图例与联合国土地覆盖分类系统（LCCS）兼容。该系统依托一套自动化预处理与分类流程链构建。最终，这套全球土地覆盖图已通过国际土地覆盖专家团队的验证，相关验证报告也对用户社区开放获取。
