ee.Join.saveBest
Returns a join that pairs each element from the first collection with a matching element from the second collection. The match with the best join measure is added to each result as an additional property. Join measures are produced when withinDistance or maxDifference filters are used as the join condition.

matchKey | String | The key used to save the match. |
