ABSTRACT

The marine geographic information system (GIS) is used as an effective tool for spatial information data collection and storage, access and management, analysis and problem solving, and its application in maritime delimitation. Through research, it is found that the simple GIS maritime delimitation technology has many defects in dealing with the complex territorial sea area division. For example, the algorithm is not strict and the data structure is not uniform, which cannot meet the demand of high-precision maritime delimitation technology. To this end, the method of ocean coordinates determination based on Bessel method can improve the vector data in GIS, and provides a solution for high-precision ocean demarcation model.
