Abstract: GIS interoperation is desired of the spatial information science and technology. To support the implementation of GIS interoperation, this paper presents three design patterns: data adapter, façade and bridge. These design patterns can provide reusable implementation strategies of GIS software to fulfill the interoperation of spatial data and processes. And they can also improve the quality and efficiency of interoperable GIS software both in the design and the implementation phases.

Key words: design patterns, interoperation, GIS
