| Abstract: | A framework of public meteorological services website using GIS analysis as the core is presented.The correlation between GIS and the meteorological elements with multiple temporal-spatial scales,the position of GIS in hierarchy of the logical system,and the web page functions of one,two and three-dimensional analysis maps are expounded.Meanwhile,some of the key technologies the GIS applications faced are analysed in-depth.For example,the meteorological elements interpolation of pre-cut weighted geographic boundaries,the generation of netCDF file,and two and three-dimensional visualisation technique,etc.This system has been applied in the websites including China Weather Networks,Sichuan Meteorological Networks and Chengdu Public Meteorological Services Networks. |
