對這個集合套用篩選器。

傳回經過篩選的集合。

用量傳回
FeatureCollection.filter(filter)集合
引數類型詳細資料
這個：collection集合Collection 執行個體。
filter篩選器要套用至這個集合的篩選器。

範例

程式碼編輯器 (JavaScript)

// Load a collection of counties.
var counties = ee.FeatureCollection('FAO/GAUL_SIMPLIFIED_500m/2015/level2');

// Filter the collection to get Denver county.
var denverCollection = counties.filter(ee.Filter.eq('ADM2_NAME', 'Denver'));

// Or you can use a string filter (equivalent to the above):
// var denverCollection = counties.filter("ADM2_NAME == 'Denver'");

Map.centerObject(denverCollection, 9);
Map.addLayer(denverCollection, null, 'Denver');
