ee.FeatureCollection.filterBounds

可依幾何交集篩選集合的捷徑。如果集合中的項目足跡無法與指定幾何圖形相交,就會遭到排除。

這相當於 this.filter(ee.Filter.bounds(...))。

傳回經過篩選的集合。

用量傳回
FeatureCollection.filterBounds(geometry)集合
引數類型詳細資料
這個:collection集合Collection 執行個體。
geometryComputedObject|FeatureCollection|Geometry要與之相交的幾何圖形、特徵或集合。

範例

程式碼編輯器 (JavaScript)

// FeatureCollection of global power plants.
var powerPlants = ee.FeatureCollection('WRI/GPPD/power_plants');

// FeatureCollection of counties in Oregon, USA.
var oregonCounties = ee.FeatureCollection('TIGER/2018/States')
                         .filter('STATEFP == "41"');

// Filter global power plants to those that intersect Oregon counties.
var oregonPowerPlants = powerPlants.filterBounds(oregonCounties.geometry());

// Display Oregon power plants on the map.
Map.setCenter(-120.492, 44.109, 6);
Map.addLayer(oregonPowerPlants);
