dc.description.abstract Recent marine accidents have been increased, in particular, engine damage, collision and grounding are given a great deal of proportions out of them. Whilst the study of collisions between ship and ship were carried out actively. However, due to the topography and artificial structures, the study of risk was relatively sluggish. So far, the reason of relatively sluggish of study on topography and artificial structures than ship to ship collision is that, difficulty of constructing efficient data and the massive topography data. The shoreline topography, that contained in ENC(Electronic Navigational Chart) are varies depending on the Chart level. In case of 4 Level(Coast Chart), there are more than 10,500 Objects. There are some polygons constructed by more than 1,500,000 vertice. This paper showing the method of analyzing topography danger and how to build efficient topography data on the analyzing system of ship danger that receive massive ship's position informations. Through previous cases and studies, examined methods and results of danger analyzing systems. And describe about AIS system and nautical charts briefly. To build land topography and show the study result, we use ENC, so, we also carrying out brief study about ENC. Secondly, show detailed study on clipping topography data. And to verify the effectiveness of result, display on ECS(Electronic Chart System) with non-clipping data. To analyzing topography danger, ES(Environment Stress) Model with necessary modifications applied. ES Model has two parts that are Ship Danger and Land Danger. This paper use Land Danger display methods of ES Model. The display method is showing danger left and right turns of 90 degrees on ship's heading. The danger is recognized intuitively by user. The method on this paper is limited to land topography and has overhead costs to pre-processing. And on some situations, the danger seems a straight line on one direction(even if it is not incorrect data). These will be dealt with in the future study -
