CORINE Land Cover Change 2006-2012 (vector), Europe, 6-yearly - version 2020_20u1, May 2020

Corine Land Cover Change 2006-2012 (CHA0612) is one of the Corine Land Cover (CLC) datasets produced within the frame the Copernicus Land Monitoring Service referring to changes in land cover / land use status between the years 2006 and 2012. CHA is derived from satellite imagery by direct mapping of changes taken place between two consecutive inventories, based on image-to-image comparison. CLC service has a long-time heritage (formerly known as "CORINE Land Cover Programme"), coordinated by the European Environment Agency (EEA). It provides consistent and thematically detailed information on land cover and land cover changes across Europe. CLC datasets are based on the classification of satellite images produced by the national teams of the participating countries - the EEA members and cooperating countries (EEA39). National CLC inventories are then further integrated into a seamless land cover map of Europe. The resulting European database relies on standard methodology and nomenclature with following base parameters: 44 classes in the hierarchical 3-level CLC nomenclature; minimum mapping unit (MMU) for status layers is 25 hectares; minimum width of linear elements is 100 metres. Change layers have higher resolution, i.e. minimum mapping unit (MMU) is 5 hectares for Land Cover Changes (CHA), and the minimum width of linear elements is 100 metres. The CLC service delivers important data sets supporting the implementation of key priority areas of the Environment Action Programmes of the European Union as e.g. protecting ecosystems, halting the loss of biological diversity, tracking the impacts of climate change, monitoring urban land take, assessing developments in agriculture or dealing with water resources directives. CLC belongs to the Pan-European component of the Copernicus Land Monitoring Service (https://land.copernicus.eu/), part of the European Copernicus Programme coordinated by the European Environment Agency, providing environmental information from a combination of air- and space-based observation systems and in-situ monitoring.

科里内陆地覆盖变化2006-2012（CHA0612）是哥白尼陆地监测服务（Copernicus Land Monitoring Service）框架下产出的科里内陆地覆盖（Corine Land Cover, CLC）数据集之一，聚焦2006年至2012年间的陆地覆盖与土地利用状况变化。CHA数据集通过逐景影像比对的方式，对两次连续调查期间发生的变化开展直接制图，其数据源为卫星影像。CLC项目拥有深厚的历史积淀（前身为“科里内陆地覆盖计划”），由欧洲环境署（European Environment Agency, EEA）统筹协调。该项目可为全欧洲范围提供一致性强、主题细节丰富的陆地覆盖及陆地覆盖变化相关信息。CLC数据集的制作基础是参与国（欧洲环境署成员国与合作国，即EEA39区域）的国家级团队对卫星影像开展的分类工作，随后各国的CLC调查成果将被整合为一张无缝衔接的欧洲陆地覆盖地图。最终形成的欧洲级数据库遵循标准方法与命名规范，核心基础参数如下：采用三级层级化的CLC命名体系，共计44个分类类别；现状图层的最小制图单元（minimum mapping unit, MMU）为25公顷，线状要素的最小宽度为100米。而变化图层的分辨率更高：陆地覆盖变化（Land Cover Changes, CHA）图层的最小制图单元为5公顷，线状要素的最小宽度仍为100米。CLC数据集可提供重要的数据支撑，助力欧盟环境行动计划的关键优先领域落地实施，例如保护生态系统、遏制生物多样性丧失、追踪气候变化影响、监测城市土地扩张、评估农业发展态势，以及落实水资源相关指令等。CLC项目隶属于哥白尼陆地监测服务（Copernicus Land Monitoring Service, https://land.copernicus.eu/）的泛欧洲组成部分，该服务是由欧洲环境署协调的欧洲哥白尼计划的组成单元，通过空基、天基观测系统与原位监测相结合的方式提供环境信息。更多关于CLC产品说明（含制图指南）的信息可查阅https://land.copernicus.eu/user-corner/technical-library/。CLC分类体系的详细说明可查阅https://land.copernicus.eu/user-corner/technical-library/corine-land-cover-nomenclature-guidelines/html/。
