由欧洲联盟委员会联合研究中心协调的一个由30个研究小组组成的国际伙伴关系编制了一个新的2000年全球土地覆盖数据库(GLC2000)。该数据库包含两个级别的土地覆盖信息--每个大陆的详细、区域优化的土地覆盖传说，以及一个主题不太详细的全球传说，它将区域传说协调成一个一致的产品。土地覆盖图都是基于Spot 4上植被传感器的日常数据，尽管一些地区的地图涉及使用其他地球观测传感器的数据来解决具体问题。逐个区域进行了详细的图例定义、影像分类和地图质量保证。全球的产品就是由这些集合而成的。该数据库旨在为科学方案、决策者、环境公约秘书处、非政府组织和发展援助项目的用户提供服务。Http://www.gvm.jrc.it/glc2000.为所有非商业应用程序免费提供区域和全球数据
A new global land cover database for the year 2000 (GLC2000) has been produced by an international partnership of 30 research groups coordinated by the European Commission's Joint Research Centre. The database contains two levels of land cover information-detailed, regionally optimized land cover legends for each continent and a less thematically detailed global legend that harmonizes regional legends into one consistent product. The land cover maps are all based on daily data from the VEGETATION sensor on-board SPOT 4, though mapping of some regions involved use of data from other Earth observing sensors to resolve specific issues. Detailed legend definition, image classification and map quality assurance were carried out region by region. The global product was made through aggregation of these. The database is designed to serve users from science programmes, policy makers, environmental convention secretariats, non-governmental organizations and development-aid projects. The regional and global data are available free of charge for all non-commercial applications from http://www.gvm.jrc.it/glc2000.
