ee.ImageCollection.filterDate
使用集合让一切井井有条
根据您的偏好保存内容并对其进行分类。
按日期范围过滤集合的快捷方式。开始时间和结束时间可以是日期、数字（解释为自 1970-01-01T00:00:00Z 以来的毫秒数）或字符串（例如“1996-01-01T08:00”）。基于“system:time_start”。
这相当于 this.filter(ee.Filter.date(...))；如需了解其他日期过滤选项，请参阅 ee.Filter 类型。
返回过滤后的集合。
| 用法 | 返回 |
|---|
ImageCollection.filterDate(start, end) | 集合 |
| 参数 | 类型 | 详细信息 |
|---|
此：collection | 集合 | Collection 实例。 |
start | 日期|数字|字符串 | 开始日期（含）。 |
end | Date|Number|String，可选 | 结束日期（不含）。可选。如果未指定，则会创建一个从“start”开始的 1 毫秒范围。 |

代码编辑器 (JavaScript)
// A Landsat 8 TOA image collection intersecting a specific point.
var col = ee.ImageCollection('LANDSAT/LC08/C02/T1_TOA')
.filterBounds(ee.Geometry.Point(-90.70, 34.71));
// Filter the collection by date using date strings.
print('2020 images', col.filterDate('2020', '2021'));
print('July images, 2020', col.filterDate('2020-07', '2020-08'));
print('Early July images, 2020', col.filterDate('2020-07-01', '2020-07-10'));
print('Include time (13 hours, July 7, 2020)',
col.filterDate('2020-07-05T06:34:46', '2020-07-05T19:34:46'));
// Use milliseconds since Unix epoch.
print('Milliseconds inputs', col.filterDate(1593967014062, 1595349419611));
// Use ee.Date objects.
