依据境界之间的拓扑数据，采用拓扑分析、边界追踪、边界闭环构建、边界约束下的凸分解、区域填充和边界符号化等技术手段，提出了 OpenGL渲染环境下军用数字地图政区的构建方法。通过具体的软件开发和真实数据的测试，证明该方法生成政区准确、符号美观，可适用于不同比例尺下数字地图的显示。该算法具有较强的通用性，遵循国军标的相关规定，已经在相关数字地图软件中得以应用。

This paper proposes a construction method about administrative division in military dig-ital map under OpenGL rendering environment,according as the technical means of topology data about ambit,topology analysis,boundary tracking and closed-loop construction,convex decompo-sition under boundary constraints,region filling and boundary symbolization.By means of soft-ware development and real data test,it is proved that the method of generating accurate adminis-trative district and beautiful symbol can be used for the display of digital map with different scales.The algorithm has strong generality,complies with the relevant national military standard, and has been applied in some digital map softwares.
