Research on GIS Interoperability
GIS互操作研究

Firstly analyses GIS Geographic Information System interoperability. GIS interoperability have two facet-GIS data interoperability and GIS founction interoperability. Using GML (Geography Markup Language) is a good approach to achieve GIS data interoperability; through extending the thinking of component GIS and analysing the model of component registration, GIS founction interoperability can be solved better. Finally,an architecture of GIS interoperability is proposed.
