Research of knowledge base of active statistical map cartography

This paper describes the active statistical map of cartographic concepts and application requirements, focusing on analysis of active statistical map-making process used in the structural design of the knowledge base, the use of knowledge classification and knowledge of decomposition and renewal strategy, which uses a Bayesian probability model as a knowledge filter model for the screening, and analyzes the advantages and disadvantages of the model. On this basis, the design of a probabilistic model based on Bayesian statistical map of the knowledge update the system. Verify the statistical map of the rationality of structural design knowledge base and update the strategy is feasible.
