A positive distance expands the geometry, while a negative distance contracts it. The `distance` is in meters unless a `proj` projection is given, in which case the units are in the projection's coordinate system. An optional `maxError` sets tolerance. The method returns a new `Feature` that represents the geometry buffered with the parameters used.\n"]]
