Google Earth Engine (GEE) - select the data of the specified research area to filter data according to different time periods

To filter remote sensing images of different time periods in GEE, you can use ee.Filter.date()filter. Here is a basic code example:

// 定义遥感影像集合
var collection = ee.ImageCollection('MODIS/006/MOD13Q1')
                  .filter(ee.Filter.date('2018-01-01', '2021-12-31'));

// 按照时间段（年份）筛选
var collection2018 = collection.filter(ee.Filter.date('2018-01-01', '2018-12-31'));
var collection2019 = collection.filter(ee.Filter.date('2019-01-01', '2019-12-31'));
var collection2020 = collection.filter(ee.Filter.date('2020-01-01', '2020-12-31'));
var collection2021 = collection.filter(ee.Filter.date('2021-01-01', '2021-12-31'));

ee.Filter.or(var_args)

Combine two or more filters using boolean OR.

Returns the constructed filter.

Arguments:
