In recent years,geological hazard identification based on integrated remote sensing has been widely carried out,featuring wide surveyed areas,high time pressure,and heavy tasks.To meet the demand for the effective utilization of multi-source remote sensing data,multi-person collaboration,and quick result integration,along with the requirements of geological hazard identification tools,this study established a 3D geological hazard identification information platform.This platform,adopting a C/S architecture,allows for the effective organization and management of multi-source optical and radar remote sensing data,vector data,and 3D models and possesses functions such as the loading of multi-source data,multi-person collaboration,quick interpretations and identification,and result expression and output.This platform has successively supported fine-scale identification of hidden hazards and multiple emergency security efforts in national key areas with high geologic hazard susceptibility,such as Gansu,Yunnan,and Sichuan provinces.The application results indicate that this platform allows for rapid data supply and assists in improving work efficiency.
