algorithm | Function | The operation to map over the images or features of the collection. A JavaScript function that receives an image or features and returns one. The function is called only once and the result is captured as a description, so it cannot perform imperative operations or rely on external state. |
dropNulls | Boolean, optional | If true, the mapped algorithm is allowed to return nulls, and the elements for which it returns nulls will be dropped. |
