Makes a new collection that is a copy of the images in primary, adding all the bands from the image in secondary with a matching ID. If there are no matching IDs, the resulting collection will be empty. This is equivalent to an inner join on ID with merging of the bands of the result.
Note that this algorithm assumes that for a matching pair of inputs, both have the same footprint and metadata.
Usage
Returns
ImageCollection.combine(secondary, overwrite)
ImageCollection
Argument
Type
Details
this: primary

The primary collection to join.
