ee.FeatureCollection.filterDate
Organiza tus páginas con colecciones
Guarda y categoriza el contenido según tus preferencias.
Atajo para filtrar una colección por un período. El inicio y el final pueden ser fechas, números (interpretados como milisegundos desde 1970-01-01T00:00:00Z) o cadenas (como "1996-01-01T08:00"). Se basa en "system:time_start".
Esto equivale a this.filter(ee.Filter.date(...)); consulta el tipo ee.Filter para ver otras opciones de filtrado por fecha.
Devuelve la colección filtrada.
| Uso | Muestra |
|---|
FeatureCollection.filterDate(start, end) | Colección |
| Argumento | Tipo | Detalles |
|---|
esta: collection | Colección | Instancia de Collection. |
start | Fecha|Número|Cadena | Fecha de inicio (inclusive) |
end | Fecha|Número|Cadena, opcional | Fecha de finalización (no incluida). Opcional. Si no se especifica, se crea un rango de 1 milisegundo a partir de "start". |
