Automated Generalization-Chain and Cartographic-Generalization Process-Control Model

The automated generalization process-control is a new research field of automated cartographic generalization. The concept of automated generalization-chain was put forward, and the characteristics of the chain and generalization-knowledge lib were described. Supported with the example of large scale street block generalization, the automated generalization steps of checking spatial original data based on cartographic generalization knowledge, mining cartographic generalization tasks by checking spatial data, separating and regrouping cartographic generalization tasks, and assembling generalization chain automatically with these tasks and saving it as CASE were presented. A new automated cartographic-generalization process-control model based on automated generalization-chain was proposed. The cartographic generalization process was automated by automated control method. The result shows that this process control model improves the cartographic-generalization intelligence and automatization level greatly, and promotes the cartographic-generalization system info directly.
