基于MyEclipse开发环境的低空目视航图系统构建
|
摘要
现有民航航图中,仪表用飞行航图不含地面参照物,目视飞行用航图也仅包含基本地形轮廓。因此,主要以目视规则运行的通航飞行器迫切需要一款能够包含禁飞区信息、危险障碍物、城镇居民点等各类地表情报信息的低空目视航图系统。本文介绍一种低空目视航图系统的基础架构及其基本功能。该系统采用MyEclipse作为开发环境,开发语言为JAVA;通过SQL Server数据库管理系统管理"基础地理信息数据库、专题地理信息数据库、文件数据库",形成数据中心;数据中心采集各数据库相关信息为客户端提供数据服务,各数据库定期更新和完善各相关数据;利用OpenLayer开发低空目视航图信息系统的WebGIS客户端,并将各基础数据、专题数据、管理数据图层叠加到用户访问界面。
In the current civil aviation chart, the instrument flight chart does not contain ground reference objects, and the visual flight chart contains only the basic terrain profile. Therefore, the general aerial vehicle, which mainly operates by visual rules, urgently needs a low altitude visual flight rule(VFR) system which can contain the information of no-fly zone, dangerous obstructions, urban settlement and other various surface intelligence information. The basic framework and basic functions of a low altitude VFR system are briefly introduced. This low altitude VFR system is based on the exploitation environment of MyEclipse, and the development language is JAVA. The basic geographic information database, subject geographic information database and file database of data center are managed by SQL Server system. The data center collects the relevant information of each database to provide the data service for the client, and each database regularly updates and perfects the relevant data. Finally, the WebGIS client of the low-altitude visual navigation map information system is developed by using OpenLayer, and the basic data, special data and management data layer are superimposed on the user access interface.
