地理信息系统技术在无人驾驶飞艇中开发应用

介绍地理信息系统（GIS）技术和当前应用，以及Maplnfo软件与传统GIS技术相比在数字地图制作方面的优点，重点阐述了MapInfo在制作电子地图方面的实现方法。通过对MapX控件功能的描述，结合无人驾驶飞艇飞行航线的显示和设置需求，详细地论述了在VC中利用MapX控件开发数字地图显示功能的方法和设计思路，给出了软件设计的流程，实现了飞艇的当前位置、飞行航迹和飞行的动态过程在数字地图上的实时显示，并可在线设置、上传和下载飞行航线。

Development of geographic information system technology and its application to an unmanned airship

The contents of the Geographic Information System（GIS） technology and its current application are briefly presented. The implementation of designing digital map with MapInfo software is expatiated after analyzing MapInfo＇s advantages compared with traditional GIS software. Considering the requirements of an unmanned airship flight route display and set, the paper proposes a method and design of developing digital map in VC environment with the MapX OCX（Object Linking and Embedding Control Extension）. The software design process is given. The real-time displays of the current location of the airship, its flight-track, and the dynamic effect of flight are realized in the digital map. The editable function of flight routes is also realized. Results show that the method is effective and practicable.
