生成三角网处理坡坎方面，网中每一个三角形只能是坡顶线上相邻两点连接坡脚线上对应一点，或者是坡脚线相邻 ...
我觉得算方量最精确的算法是三角网。但用三角网直接两期算我觉得还是会增大误差。我的理论就是用两期的三角网同时算到一个平面。然后计算差值。这样就不存在你们说的双线性差值带来的烦恼了。 一个非测绘专业的十年测量员的理解，有可能有误清不要见笑。 本帖最后由 树櫴希德 于 2014-5-5 21:06 编辑
目的是想改进CASS三角网两期间土方计算显示结果，如图： 黄色为原地面标高，青色为完成面标高，红框内粉红色为填挖高度，三角形编号，面积，单个三角形方量已经搞定 用蓝图老师的面积标注程序批量标注三角形面积 其实相对于你这个问题我更好奇为什么会有两个点位一样而高程不一样的点？
挖填前后测的？那怎么保证它的坐标在同一处的？打了桩，还是第二次对第一次测的坐标进行放样？ 闭合多边形,有什么要求啊,根本用不了啊 一般情况只会关心挖填前后的总方量变化，有必要关心每一个三角形的变化么？这是什么行业要求这么严格的？ 那是我根据CASS生成的DTMTF.LOG文件提取的，甲方需要查看每个节点填挖高度，高程等要素。CASS这方面还有待改进 上传一个增强属性快 用INSERT插入
