Study on 3D GIS-based navigation data evaluation system

Based on SuperMap Object component GIS technology,a three-dimensional navigation data evaluation system is presented utilizing decode ARINC424 data and GIS data integration,which has the functions such as: navigation data quality analysis,terminal area procedure verifying,NOTAM spatial analysis,information query,simulated navigation.Study of the system can not only improve accuracy and efficiency of verifying data in airborne navigation database,but also enhance the ability of airline operational persons to analyze and utilize aeronautical data,thereby improving the level of airline operation safety and efficiency.
