A dynamic airspace grid map based on 3D subdivision framework

Abstract. This paper proposes a dynamic airspace grid map based on a 3D subdivision framework to address the lack of standardized modeling framework in current spatial management, difficulties in finely managing small scale areas, and low efficiency issues. The dynamic airspace grid map adopts the GeoSOT-3D subdivision framework, which can seamlessly encode and manage the three-dimensional spatial domain at multiple levels without stacking. Grid map also models static and dynamic airspace, including obstacles, dynamic airspace attributes, aircraft, and can achieve intelligent visualization of time- variance airspace. Finally, the dynamic airspace grid map can organize and store static and dynamic spatial data based on a 3D subdivision framework to ensure the orderliness and security of the airspace domain.
