Functions

closestDate(col[, clip_to_first])	Make a composite in which masked pixels are filled with the.
compositeByMonth(collection[, composite_function, ...])	Make a composite at regular intervals parsing a composite.
compositeRegularIntervals(collection[, interval, ...])	Make a composite at regular intervals parsing a composite.
max(collection, band)	Make a max composite using the specified band.
medoid(collection[, bands, discard_zeros])	Medoid Composite. Adapted from https://www.mdpi.com/2072-4292/5/12/6481.
medoidScore(collection[, bands, discard_zeros, ...])	Compute a score to reflect 'how far' is from the medoid.

geetools.composite.closestDate(col, clip_to_first=False)

Make a composite in which masked pixels are filled with the.

last available pixel. Make sure all image bands are casted.

Parameters:

clip_to_first – whether to clip with the ‘first’ image geometry

geetools.composite.compositeByMonth(collection, composite_function=None, composite_args=None, composite_kwargs=None)

Make a composite at regular intervals parsing a composite.

function. This function MUST return an ImageCollection and its first argument must be the input collection. The default function (if the argument is None) is lambda col: col.median().

geetools.composite.compositeRegularIntervals(collection, interval=1, unit='month', date_range=(1, 0), date_range_unit='month', direction='backward', start=None, end=None, composite_function=None, composite_args=None, composite_kwargs=None)

Make a composite at regular intervals parsing a composite.

function. This function MUST return an ImageCollection and its first argument must be the input collection. The default function (if the argument is None) is lambda col: col.median().

geetools.composite.max(collection, band)

Make a max composite using the specified band.

geetools.composite.medoid(collection, bands=None, discard_zeros=False)

Medoid Composite. Adapted from https://www.mdpi.com/2072-4292/5/12/6481.

Parameters:

• collection (ee.ImageCollection) – the collection to composite

• bands (list) – the bands to use for computation. The composite will include all bands

• discard_zeros (bool) – Masked and pixels with value zero will not be use for computation. Improves dark zones.

Returns:

the Medoid Composite

Return type:

ee.Image

geetools.composite.medoidScore(collection, bands=None, discard_zeros=False, bandname='sumdist', normalize=True)

Compute a score to reflect ‘how far’ is from the medoid.

Same params as medoid() .
