ee.ImageCollection.geometry

Extracts and merges the geometries of a collection. Requires that all the geometries in the collection share the projection and edge interpretation.

Caution: providing a large or complex collection as input can result in poor performance. Collating the geometry of collections does not scale well; use the smallest collection that is required to achieve the desired outcome.

Note: If only a bounding box around the collection is needed, consider using Collection.bounds instead.
