地块面积在转换前后经常出现面积偏差,经分析可知当前国内地块面积出现误差多由圆弧段的拟合造成,通过将圆弧段模型泰勒展开,经过反算,得到满足一定精度条件下拟合线段的数量,保证地块面积在转换前后达到一定精度需求. 该方法原理简单,既保证了数据入库后面积满足精度需求,又不会增加数据的复杂程度.

There is always area deviation during the conversion of different data. It is the curve fitting that causes the de-viation of land area nowadays. By analyzing the Taylor expansion of curve model,the number of poly-lines is calculated which satisfies the demands of the precision control during the land area identification. The new method is very simple,which not on-ly ensures the land area's precision but also does not increase the complexity of the ownership conversion.
