海岸带数据集成中的空间坐标转换方法研究

Spatial Coordinate System Transformation for Coastal Data Integration

就海岸带空间数据集成中所涉及的多种坐标系统一、多种地图投影转换等问题作了详细分析,并提出了有效的解决方案。

This paper analyzes the different reference frames and map projections which are involved in coastal space data-integration, and proposes some effective methods for unifying different reference frames and transforming different map projections. Particularly, the relation between the order of a polynomial and control points is discussed. The methods proposed for map projection transformation in this paper can be used in other fields, e.g. integration of landform and seabed.
