        }
    }
    if (dsg instanceof DatasetGraphSpatial) {
        DatasetGraphSpatial x = (DatasetGraphSpatial) dsg;
        return x.getSpatialIndex();
    }
    Log.warn(SpatialOperationWithCircleBase.class, "Failed to find the spatial index : tried context and as a spatial-enabled dataset");
    return null;
