ee.ImageCollection.filterDate
Mantenha tudo organizado com as coleções
Salve e categorize o conteúdo com base nas suas preferências.
Atalho para filtrar uma coleção por um período. O início e o fim podem ser datas, números (interpretados como milissegundos desde 1970-01-01T00:00:00Z) ou strings (como "1996-01-01T08:00"). Com base em "system:time_start".
Isso é equivalente a this.filter(ee.Filter.date(...)); consulte o tipo ee.Filter para outras opções de filtragem por data.
Retorna a coleção filtrada.
| Uso | Retorna |
|---|
ImageCollection.filterDate(start, end) | Coleção |
| Argumento | Tipo | Detalhes |
|---|
isso: collection | Coleção | A instância da coleção. |
start | Date|Number|String | A data de início (inclusive). |
end | Date|Number|String, opcional | A data de término (exclusiva). Opcional. Se não for especificado, um intervalo de 1 milissegundo começando em "start" será criado. |
Exemplos
Editor de código (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.
print('ee.Date inputs', col.filterDate(ee.Date('2020'), ee.Date('2021')));
// Use an ee.DateRange object.
var dateRange = ee.DateRange('2020-07-01', '2020-07-10');
