Composite obstacle limitation surfaces are defined by overlaying the obstacle limitation requirements for departure and approach. Based on the assumption that airfield clearance zone consists of 3D lumps, adaptive algorithm for resolving 3D lumps is proposed, which can be used to design an airfield clearance condition evaluation procedure that can evaluate superelevation of topographical data. A programing method for airfield topography information collection based on Google Earth is proposed. By overlaying the three layers that include topographical information, obstruction information and image of airfield clearance zone, a stereoscopic display of airfield clearance condition management platform is established under ArcGIS. Thereby, an airfield clearance condition evaluation and management system is formed, which contains topographical information collection, evaluation and management of airfield clearance zone.

Abstract


Composite obstacle limitation surfaces are defined by overlaying the obstacle limitation requirements for departure and approach. Based on the assumption that airfield clearance zone consists of 3D lumps, adaptive algorithm for resolving 3D lumps is proposed, which can be used to design an airfield clearance condition evaluation procedure that can evaluate superelevation of topographical data. A programing method for airfield topography information collection based on Google Earth is proposed. By overlaying the three layers that include topographical information, obstruction information and image of airfield clearance zone, a stereoscopic display of airfield clearance condition management platform is established under ArcGIS. Thereby, an airfield clearance condition evaluation and management system is formed, which contains topographical information collection, evaluation and management of airfield clearance zone.
