| 摘 要： | 针对特战实训演练中大比例尺军事地形图数据不足、现势性较差的问题,从特战用图需求出发,基于众源地理数据提出了一种快速、高效、经济、准确的大比例尺军事地形图测制方法。首先,介绍了众源地理数据的概念和特点,研究了众源地理数据的来源和获取方法。然后,在顾及军事地形图与民用地形图之间制图表达的差异后,设计了利用众源地理数据绘制大比例尺军事地形图的工艺流程。最后,基于ArcMap,绘制了某地1∶1万军事地形图并进行实验验证和精度分析。实验结果表明,该方法既可有效提高作业效率,又能满足成图精度要求,可为军事教学训练、指挥员用图决策提供重要参考。

| Abstract: | Aiming at the problems of insufficient data and poor current situation of large-scale military topographic map in special operations training and drilling, we propose a fast, efficient, economical and accurate large-scale military topographic map measurement method based on the crowd sourcing geographic data. Firstly, we introduce the concept and characteristics of the crowd sourcing geographic data, and analyze the sources and acquisition methods of the crowd sourcing geographic data. Then, we design a technological process of drawing large-scale military topographic map using the crowd sourcing geographic data as a result of catering for the differences between military topographic map and civil topographic map. Finally, the 1∶10 000 military topographic map of a certain place is drawn based on ArcMap, and the experimental verification and accuracy analysis are carried out. The experimental results show that the method can not only effectively improve the operation efficiency, but also meet the requirements of mapping accuracy. It can provide an important reference for military teaching and training and commander’s decision-making. |
