Flight trajectory data either in AMOC or ETMS are provided as latitude and longitude values. In order to visualize these values, a GIS application was developed in VBA (Visual Basic for applications) using ARCView 8.2. This application can directly read data from an Access database. It converts the flight legs latitude and longitude into trajectories. This application was used for: 中国航空网 www.aero.cn 航空翻译 www.aviation.cn 本文链接地址:AERO2K Flight Movement Inventory Project Report(16)
