RESEARCH ON INTEGRATION OF SDI WITH GEOLOGICAL AND METEOROLOGICAL DATA FOR METEOROLOGICAL FORECAST AND ALARM OF GEOLOGICAL DISASTERS

摘要

In order to forecast the geological disaster, a forecasting model of geological disasters in Hefei area has been established. The model is based on raster data model. Because that the data from local SDI are vector data, some pretreatment must be done before they are used in the forecasting model. Some data, such as geological data, meteorological data and precipitation, has been translated into grid network data, which grid cell is 5KmX5 Km. In order to integrate these professional data with the data from local SDI, a new integrating way has been put forth in this paper. In our case study, the forecasting model has been used to forecast the geological disasters in Hefei area successfully by using the integrating way. The successful running of this forecasting model demonstrated that this integrating way is feasible and can be used for reference of integrating other professional data with SDI data.
