ee.ImageCollection.filterDate
Mit Sammlungen den Überblick behalten
Sie können Inhalte basierend auf Ihren Einstellungen speichern und kategorisieren.
Kürzel zum Filtern einer Sammlung nach einem Zeitraum. Start und Ende können Datumsangaben, Zahlen (die als Millisekunden seit dem 01.01.1970 um 00:00:00 Z interpretiert werden) oder Strings (z. B. „1996-01-01T08:00“) sein. Basierend auf „system:time_start“.
Dies entspricht this.filter(ee.Filter.date(...)); weitere Optionen zum Filtern nach Datum finden Sie unter ee.Filter.
Gibt die gefilterte Sammlung zurück.
Nutzung | Ausgabe |
---|
ImageCollection.filterDate(start, end) | Sammlung |
Argument | Typ | Details |
---|
So gehts: collection | Sammlung | Die Sammlung. |
start | Datum|Zahl|String | Das Startdatum (einschließlich). |
end | Datum|Zahl|String, optional | Das Enddatum (ausschließlich). Optional. Wenn nicht angegeben, wird ein 1-Millisekunden-Bereich ab „start“ erstellt. |
