e-Navigation strategy IMO promotes is defined as it is necessary for network and information standard to provide various maritime safety informations to in land and on board users, and it is expected to provide a large amount and diverse kinds of maritime spatial information services to them. However, as there are some limits to transmit that by current mobile maritime communication technologies, it is required to simplify and optimize the information. In this study, tree node method is applied to ENC using Douglas-Peucker algorithm and we arranged the effect of simplified spatial information through CALS method which compensates the defect of basic tree node method.
