On the basis of analyzing the geometry characteristic of geologicsection, the data model of section is built.
在分析地质剖面图的几何特征的基础上，建立了地质剖面图的数据模型。

Geologicsection is an important diagram of reflecting the structure and lithology of stratum. It is the most intuitionistic and effectual expression of stratum.
地质剖面图是反映地层结构、岩体属性特征的重要成果图件，是地层在垂向上最直观最有效的表达方式。

Identification of condensed section is not only the key to understanding of sequence structure, but also critical to analysis of global relative sea level changes during geologic history.
