| Abstract: | A GIS - based system for early warning and forecasting of geological disasters is introduced in this paper. SQL SERVER 2（130 , Visual Basic 6. 0 and back -end running of Surfer8. 0 are applied in the system. Using real time rainfall observation, radar data and the quantitative precipitation forecasts （QPF） of NWP models and the nowcast system SWIFT,the system produces ranked geological disaster potential for 3 -hour,24 -hour,and 48 -hour lead times based on the data of geological structure and the distribution of areas liable to geological disaster,as well as the statistical relationship between historical samples of geological disasters and rainfall data. The results are presented on the platform of GIS ,which are at the same time published to the public and the local government via TV, 12121 ,platform for decision -making meteorological service ,mobile phone short message and internet etc. |
