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 VFR system which can contain the information of no-fly zone, dangerous obstructions, urban settlement and other various surface intelligence information. This paper will briefly introduces the basic framework and basic functions of a low altitude VFR system. 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.
