code: def lonlat_box(self, west, east, south, north):
          
          self._set_query(self.spatial_query, west=west, east=east, south=south,
                          north=north)
          return self
docs: Add a latitude/longitude bounding box to the query.
  
          This adds a request for a spatial bounding box, bounded by ('north', 'south')
          for latitude and ('east', 'west') for the longitude. This modifies the query
          in-place, but returns `self` so that multiple queries can be chained together
          on one line.
  
          This replaces any existing spatial queries that have been set.
  
          Parameters
          ----------
          west: float
              The bounding longitude to the west, in degrees east of the prime meridian
          east : float
              The bounding longitude to the east, in degrees east of the prime meridian
          south : float
              The bounding latitude to the south, in degrees north of the equator
          north : float
              The bounding latitude to the north, in degrees north of the equator
  
          Returns
          -------
          self : DataQuery
              Returns self for chaining calls
