“V”字型法则约束下基于GIS的地层界线计算机辅助连接

GIS-based computer-aided connection of stratigraphic boundary points pursuant to the“V”-shaped pattern rule

在计算机辅助地质填图系统中，如何在数字化的地形图上进行地层界线点的连接，并使之符合“V”字型法则，是一个具有实际意义的问题。本文深入分析了该问题的数学模型，借鉴多元统计方法中的趋势面分析方法，探讨在GIS系统中实现符合“V”字型的地质界线点的连接问题。

： How to link the observation points into stratigraphic boundaries according the “V”－shaped pattern rule on the digital topographic map in the computer－aided geological map－making system is a practical problem． On the basis of an in－depth analysis of the mathematic model of this problem and by using the trend surface analysis in the multivariate statistical analysis this paper proposes a reliable method to draw the coordinates of the nodes of the boundaries pursuant to the“V”-shaped pattern rule．
