A Rule-Based Pretreatment Mechanism for Online Mobile Map Data

In online map service for mobile users, it´s necessary to provide different map data according to different application scenarios. For a given scenario, we can preprocess the map data to satisfy the online and mobile requirements. This paper proposes a rule-based pretreatment mechanism for online mobile map data which using a novel mobile map data format Byte-Map. Through the use of pretreatment rules definition and rule engine, we can externalize the decision logic from the business logic in data pretreatment mechanism. We can also separate the data preparer and data pretreatment programmer from each other. In one hand, the data preparer can make definition and configure rules to change the pretreatment procedure, without knowing the program code. In another hand, the data pretreatment programmer can avoid modifying and re-compiling program code for handling map data from different source and type. The rule-based pretreatment mechanism made the online mobile map data pretreatment procedure flexible and extensional.
