| 摘要： |
| 地质图用于记录和显示研究区的地质特征，二维地质图通常借助于地理信息系统（GIS）编制而成。随着计算机GIS技术的发展，可以对点、定点、线和区（多边形）等地质特征做抽象处理，以联系地质图与传统地质模型。然而，GIS的传统数据结构不能通过地质图来解释复杂的概念地质模型。阐述了使用信息技术表达地质图的若干关键问题，提出了面向对象的地质数据模型GeoFeature，并构建了支持存储和管理计算机数据结构的二维圆弧拓扑结构。最后，在Minesoft软件中集成了此功能。 |

| Abstract: |
| The geological map is used to record and display geological features in study areas. Commonly, the map is compiled by Geographic Information System (GIS). With the significant progress in computer GIS technology, the geometric features such as point, vertex, line, and region (polygon) are abstracted as a linkage between the geological map and classic GIS model. However, the classic data structure in GIS cannot completely interpret the complicated conceptual geological model via the geological map. This paper analyzed the key issues of using information technology to present geological maps, proposed a geological object-oriented data model called GeoFeature, and established a two-dimensional arc-centered topology structure, which helps to store and manage the computer data structures in geological modelling tools. Finally, it is realized in the Minesoft package. |
