摘要
在地籍管理中,宗地面积是宗地多边形的重要属性。在测量数据处理过程中,经常利用坐标转换得到实际应用数据。本文推导了坐标转换前后宗地多边形面积的关系式,提供坐标转换后面积的简便快捷计算方法,通过示例分析,得到影响转换后面积变化的因素,检验坐标转换方案和转换参数的正确性。
In data processing, data are usually obtained through coordinate conversion. The cadastral parcel is one of the most important objects, and the area of a parcel is the key attribute with legal authorization. However, the parcel area based on the conversion data is different from the original area. In this paper, the authors have developed a relational equation of area computation with coordinate conversion parameters, which is a simple and convenient method for area computation. Theoretical analysis and case studies show the correctness of the equation of area calculation with coordinate conversion parameters. It is concluded that the area conversion parameters in area adjustment are easier to be detected and hence the scheme of the coordinate conversion can be selected correctly.
