【摘要】：针对现有接边方法依赖于直线型接边线,难以有效的支持非直线型接边线的数据接边质量检验的问题,提出了一种新的基于距离与角度控制的矢量面数据接边检查方法。该方法利用矢量面到接边线的距离值与弧段转角角度值作为参考量检测接边特征点,通过匹配接边特征点的方式检测接边错误位置,不依赖于接边线的具体形态,能够适用于任意类型接边线的矢量面数据接边检查。以第一次全国地理国情普查数据接边检验为实例进行验证,结果表明,该方法的漏检率为0%,准确率达到95%以上,有效地提升了接边线非直线的矢量面数据接边质量检验的准确性及效率。
[Abstract]:Aiming at the problem that the existing edge-connecting method is difficult to effectively support the quality inspection of the data of the non-linear connection line, a new method for edge checking of the data of the vector surface based on the distance and the angle control is proposed. the method uses the distance value of the vector surface to the ground line and the angle value of the arc-segment angle as the reference quantity to detect the edge-receiving characteristic point, And can be applied to the edge checking of the vector surface data of any type of connection line. The results show that the error rate of the method is 0%, the accuracy rate is over 95%, and the accuracy and efficiency of the quality inspection of the non-linear vector surface data of the ground line are effectively improved.
