Primary exploration of 3S technology in the matching design of visual alarm chart in low altitude airspace

In the paper, 3S technology was applied to the warning chart visualization design in the low altitude airspace, the route of the low altitude warning chart platform and low alarm chart matching model were explored. According to the different requirements and emergency degree of mission, multi source remote sensing data with appropriate spatial resolution was selected. The information of geographical obstacle was filtered, the database of low altitude warning chart obstacle was built, and the low altitude airspace warning chart platform was designed. Aircraft airborne positioning system was used to collect the aircraft position information, and the low altitude warning special obstacle information chart was compared with. Aircraft flying in a dangerous situation can be warned early. The RS, GIS, GNSS technology (3S technology) is applied in the design of visual chart in low altitude airspace warning, which can provide the reference for the flight scene matching research in low altitude airspace.
