Abstract. With the development of National Platform for Geospatial Information Services in China, it accumulated massive image data with multi-source, multi-temporal and multi-scale. Displaying and taking full use of these historical data can be meaningful to the users. This paper provided design and implementation of multi-temporal image service system based on national platform, which meets the requirements of different users. In this paper, the design of the overall system architecture was introduced, and different system levels stated respectively. The Key technologies presented in the third part, and the implementation displayed parts of functions of this system. Applications, that is typical, recommended in the following part. Also, future efforts and discussions were put forward in the end, which could be guided following work. The research also looks forward to the development of national platform, and the direction of services that should be provided by multi-temporal image service is already under development.
