geetools.ImageCollection.ImageCollectionAccessor.groupInterval(unit='month', duration=1)#

Transform the ImageCollection into a list of smaller collection of the specified duration.

duration (int) – The duration of each split.

Returns:

Examples

import ee, geetools

ee.Initialize()

collection = (
    ee.ImageCollection("LANDSAT/LC08/C01/T1_TOA")
    .filterBounds(ee.Geometry.Point(-122.262, 37.8719))
    .filterDate("2014-01-01", "2014-12-31")
)

split = collection.geetools.groupInterval("month", 1)
print(split.getInfo())
