Spatial information dissemination is a necessary step to make use of spatial information for which is a bridge between
the acquirement and the application of spatial information. However, conventional methods of spatial information
dissemination cannot cater to users in that not only users' personalized requirements cannot be satisfied, but initiative
dissemination service cannot be provided. In this paper, the idea of intelligent spatial information dissemination (ISD) is
proposed. Combining the ideas of personalized information retrieval, information filtering and recommender systems,
the ISD system employs user profiles and query conditions to provide two implement ways of spatial information
disseminations, namely "pull" and "push". Then, the three layers architecture of intelligent spatial information
dissemination system based on user profile model is given, and the procedure of data in the ISD system is introduced.
Also, the user profile is presented including user profile model and user profile management. Finally, the prototype
system of intelligent spatial information dissemination is presented.
