Abstract
Isolines is important to analysis meteorological data for it enables users to grasp the overall characteristics and regularity of meteorological elements in study area.Auto-generation function of meteorological isoline was realized by interpolation,gridding and contour tracking based on ArcObjiects components provided by ESRI,which was encapsulated in a COM component by ATL technology.According to meteorological data from automatic weather station(more than 200 stations) in Tianjin,the component function was tested.The results indicate that this component could be called by client program.The relevant isoline could be generated.Furthermore,the component is free from the constraints of the version and development language of client program,which is fit for the corresponding system of meteorological department based on WebGIS.
