As my question in Remove alternate features from ImageCollection was put on hold, I am clarifying the question here.
I am using google earth engine for some analysis. I can import MODIS vegetation indices data at 16-day intervals and Land Surface Temperature/Emissivity at 8 day interval.
These data are imported as earthengine ImageCollection.
Is there a way on how to filter out only those images in LST imagecollection which correspond to dates in vegetation indices data. In another way, How can I filter the LST imagecollection to get 16 day ImageCollection?
