[Abstract]:Geographic Information system (GIS) is an effective spatial analysis technology, which can manage massive geographic data, and has powerful functions of spatial analysis, visualization and graph making, which provides more possibilities for the early warning of meteorological and geological disasters. This paper summarizes the achievements and experiences of geological hazard early warning at home and abroad in recent years, and designs and establishes a meteorological risk early warning system based on ArcGIS Engine component technology. It has improved the forecast level of meteorological risks such as flood, mountain torrents, geological hazards and other meteorological risks caused by heavy rain, standardized the forecast contents and methods of meteorological risks at the national and provincial levels, and realized the automatic production of early warning and forecasting graphics products. It meets the urgent need of disaster prevention and mitigation in China. The main contents and results of this paper are as follows: (1) the data structure of meteorological data such as Micaps,NetCDF is studied and different analytic algorithms are compiled to analyze meteorological data. The visualization methods of isoline, isosurface and flow field line are studied to realize the visualization of meteorological data and the symbolization of individual data. (2) ArcGIS modeling technology and spatial analysis method are studied. According to the process of making thematic maps and corresponding specifications in the system, the automatic drawing model of thematic maps of different products is established. (3) the relevant class libraries in ArcGIS Engine are studied, and the modules and functions of the system are designed according to the specific requirements of the system. A sample version of the system is established based on ArcGIS Engine component development technology.
