Pan-European land cover/use map for 2009

GlobCorine demonstrated an automatic service that can generate in a consistent way land cover / land use maps and land change indicators, based on a CLC-compatible legend. CLC is derived from a visual identification and classification of landscape objects using high resolution images. This methodology provides high thematic accuracy but limits the update rate since it is time-consuming. Therefore, the project evaluated the use of MERIS FR time series, processed automatically to provide a more frequent update of CLC-compatible maps.
GlobCorine built upon the experience and resources available through the GlobCover project, to tune the classification chain and adapt it to the EEA needs, covering the pan-European area (including the Mediterranean basin and the European Russia), although the system could be potentially extendable globally. The project delivered two CLC-compatible pan-European land cover maps in less than two years, demonstrating efficient and quick production. The first map is based on Envisat MERIS fine resolution (300m) mode data acquired between end 2004 and mid 2006, while the second used full-year 2009 data. GlobCorine is an initiative of ESA with the partnership of EEA and is implemented by Universite' catholique de Louvain - UCL.

GlobCorine项目展示了一套自动化服务方案，可基于兼容科里兰覆盖（Corine Land Cover，简称CLC）的图例，以统一标准生成土地覆盖/土地利用地图及土地变化指标。CLC源自利用高分辨率影像开展景观对象目视识别与分类的技术方法，该方案虽具备较高的专题精度，但因流程耗时较长而限制了更新频率。为此，本项目评估了采用自动处理的MERIS FR时间序列数据，以更频繁地更新兼容CLC的地图的可行性。

GlobCorine项目依托GlobCover项目积累的经验与可用资源，对分类链路进行优化，并使其适配欧洲环境署（European Environment Agency，简称EEA）的业务需求，服务范围覆盖泛欧洲区域（含地中海盆地与欧洲俄罗斯地区），尽管该系统理论上可拓展至全球范围。本项目在不到两年的时间内便产出了两份兼容CLC的泛欧洲土地覆盖地图，展现出高效快捷的生产能力。第一份地图基于2004年末至2006年中旬获取的Envisat卫星MERIS全分辨率（300米）模式数据，第二份则采用了2009年全年的观测数据。GlobCorine项目由欧洲空间局（European Space Agency，简称ESA）发起，欧洲环境署（EEA）参与合作，并由卢万天主教大学（Université catholique de Louvain，简称UCL）负责实施。
