摘要：

A new framework of 3D aids to navigation(AtoN) setting system based on GIS and virtual simulation is proposed.Some key techniques and algorithms including 3D environment simulation,AtoN simulation,automatic setting analysis and method,efficiency evaluation are discussed in detail.Based on the above algorithms and strategies,a 3D Aids to navigation setting system based on GIS and virtual simulation was developed and obtained initial application in Shekou Harbor of Guangdong Marine Safety Administration Bureau.
