Unmanned Aerial Vehicle (UAV) swarm has become the inevitable trend of develop-ment, which will enjoy broad prospects to be applied in the future. However, the change of UAV application mode will certainly bring new technical challenges in the flight management, envi-ronmental perception, collaborative control as well as other fields. This paper considers that it can be an effective solution to realize the unified management of spatial information on the UAV plat-form by adopting the spatial grid model represented by the GeoSOT-3D, and to reduce the work-load of flight management, airborne environmental perception, and ranging in the neighborhood through the association and query of all spatial grid data.
