摘要
介绍了一种应用SharpMap技术实现将2300多个离散点降水实况显示成降水色斑图的方法。该方法首先读取地理信息和台站基础信息生成地图图层和台站数据图层,读取降水信息经等值线分析处理生成降水色斑图图层,然后将各图层以一定顺序渲染显示成湖南省降水色斑图。该方法可应用于将其他气象要素分析显示成色斑图。
A display method based on SharpMap technology is introduced in this paper. With this method, over 2300 discrete rainfall points can be shown in choroplethic map. This method reads geographic information data and basic information of station to generate map layers and data layers, then read precipitation data to generate choroplethic map through the analysis of the contour line. At last, these layers will be displayed in a certain order to show the precipitation data. This method also can be applied to analysis other meteorological data.
