现有的通过大地水准测量定量评估地壳垂直运动的技术有一个共同的特点。他们只能处理一个完整的网络系统重新连接的线路。本文提出了一种方法，基于最小二乘拟合的速度表面，能够使用分散以及连接releveled段。内置了一个选择结果的特定统计显著性水平的工具。切萨皮克湾附近的数据测试的方法的性能。结果与美国国家大地测量局的结果相当。
The existing techniques for the quantitative evaluation of vertical crustal movements from geodetic spirit levelling have one common feature. They can deal only with a complete network of systematically relevelled connected lines. This paper presents a method, based on the least-squares fitting of a velocity surface, capable of using scattered as well as connected relevelled segments. A facility to choose a specific level of statistical significance of the results is built in. The performance of the method is tested on data for the vicinity of Chesapeake Bay. The results compare well with those of the U.S. National Geodetic Survey.
