Google Earth Engine(GEE)——欧盟(EU)调查土地利用/覆盖矢量(LUCAS)点数据集无需GEE也可以下载
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。

在GEE中的展示效果,这是通过快速记载模式(ui.Map.FeatureViewLayer)加载的数据结果:
-
var fvLayer = ui.Map.FeatureViewLayer('JRC/LUCAS_HARMO/THLOC/V1_FeatureView');
-
-
var visParams = {
-
pointSize: 8,
-
color: '808080',
-
pointFillColor: {
-
property: 'inspire_plcc4',
-
mode: 'linear',
-
palette: ['ffffcc','c2e699','78c679','238443'],
-
min: 0,
-
max: 100
-
}
-
};
-
-
fvLayer.setVisParams(visParams);
-
fvLayer.setName('LUCAS herbaceous cover');
-
-
Map.setCenter(-3.8233, 40.609, 10);
-
Map.add(fvLayer);
用inspector进行点的查看:
数据集覆盖的全貌
代码:
-
var dataset = ee.FeatureCollection("JRC/LUCAS_HARMO/THLOC/V1");
-
-
// For the Inspector
-
Map.addLayer(dataset, {}, "LUCAS Points (data)", false);
-
-
dataset = dataset.style({
-
color: "489734",
-
pointSize: 3,
-
});
-
-
Map.setCenter(-3.8233, 40.609, 10);
-
-
Map.addLayer(dataset, {}, "LUCAS Points (styled green)");
