Abstract:In order to do well the public meteorological service and improve the situation that product forms of meteorological service are single, the authors mainly explore the key technologies that FY 2 satellite data of the MICAPS software are browsed and analyzed in the web environment. Selecting ArcGIS Engine as the secondary development components, the authors realized the data format conversion from FY 2 satellite image to multiple band ArcGIS’s img format raster data, which have the custom color and projection. Then choosing ArcGIS Server as the web development components, the authors constructed the web publishing platform of the satellite raster data, which can publish, query and browse the satellite data. The authors also proposed and realized the simple quantitative analysis and statistics of the data in the network environment by the GIS analysis method. Test results show that this platform can be run on the current Web environment efficiently, and it can adapt to the current bandwidth fully and meet the browse and analysis requirements of the mainstream computer. This platform supplies the meteorological information to aid in decision making for the public to know the weather in advance and the weatherman to make weather forecast and weather warning, which makes a great advance in the construction of public meteorological services for the local weather department.
