Google Earth Engine ——欧洲联盟三年一次的原地土地覆盖和土地利用数据（共有106个属性）
The Land Use/Cover Area frame Survey (LUCAS) in the European Union (EU) was set up to provide statistical information. It represents a triennial in-situ landcover and land-use data-collection exercise that extends over the whole of the EU's territory. LUCAS collects information on land cover and land use, agro-environmental variables, soil, and grassland. The surveys also provide spatial information to analyse the mutual influences between agriculture, environment, and countryside, such as irrigation and land management.
The dataset presented here is the harmonized version of all yearly LUCAS surveys with a total of 106 attributes. Each point's location is using the fields 'th_lat' and 'th_lon', that is, the LUCAS theoretical location (THLOC), as prescribed by the LUCAS grid. For more information please see Citations. Note that not every field is present for every year - see the "Years" section in property descriptions.
The text "C1 (Instructions)" in the table schema descriptions refers to this document.
欧洲联盟（EU）的土地利用/覆盖面积框架调查（LUCAS）是为了提供统计信息而设立的。它是一项三年一次的原地土地覆盖和土地利用数据收集工作，涵盖了欧盟的全部领土。LUCAS收集了关于土地覆盖和土地利用、农业环境变量、土壤和草原的信息。这些调查还提供了空间信息，以分析农业、环境和农村之间的相互影响，如灌溉和土地管理。
这里介绍的数据集是LUCAS所有年度调查的统一版本，共有106个属性。每个点的位置都使用'th_lat'和'th_lon'字段，即LUCAS的理论位置（THLOC），由LUCAS网格规定。更多信息请见引文。请注意，并不是每一年都有每个字段--见属性描述中的 "年份 "部分。
表模式描述中的文字 "C1（说明）"指的是本文件。
