The below script of 1000x1000m and 6 segments gives you 250 bands and a 17MB download.
#Ccdc icare packages download
You will end up with a lot of bands, and you cannot download more than 32MB. You can turn the CCDC segments array image into an image with a band per array element, then use getDownloadURL() to extract the data. GREEN_coefs_aoi = np.array(ccdc_mosaic.sampleRectangle(aoi).get('GREEN_coefs').getInfo()) # Get coefficients for the area of interest GREEN_coefs_poi = np.array(ccdc_mosaic.sampleRectangle(poi).get('GREEN_coefs').getInfo()) Stay connected to your loved ones in prison easily and affordably. # This pixel contains 4 time segments: OKĪrray(]]) Pigeonly offers reliable inmate communication services, including phone calls, photos, and mail.

Loop through the ee.FeatureCollection(): need input on an efficient way to iterate.Try for a 1 ha square polygon using ee.Image.sampleRectangle(): FAIL, returns the same results as for the point Geometry while the aoi contains several pixels (asset resolution = 30 m).
Try for a given ee.Geometry.Point() location: OK.I try to extract for a collection of 1 ha square polygons the bands coefficients from a preprocessed Landsat CCDC Google Earth Engine Asset ee.ImageCollection('projects/CCDC/v3').
