In order to reduce the difficulty of system maintenance and realize the dynamic integration of changing remote sensing algorithms and GIS system, this paper proposes and designs a dynamic integration framework of GIS system for remote sensing algorithms after analyzing the integration of remote sensing algorithm and GIS system. In this framework, XML technology is used to manage and describe these remote sensing algorithms which are going to be integrated. This framework makes the implementation and parameter properties of remote sensing separated from GIS system, which can cut down the coupling degree of these algorithms and enhances the scalability of the system. What is more, This framework has proved that remote sensing algorithms can be integrated dynamically in practice.
