等值线·等值面绘制和图形生成软件的设计

Contour,Contour Surface Rendering and Design of Graphics Software

随着大气观察资料的增多,如何简单便捷地将资料效用最大化是现今工作中一直困扰的难题,所以设计图形生成软件并将大气观察资料效用最大化非常必要。结合丽水市气象局日常业务工作的实际情况,使用C++Builder 6.0设计了等值线绘制软件,直接输入要素资料或者查询自动站资料,经过规则网格模型的建立、离散点资料网格化、等值线追踪、等值线平滑、等值线动态标注等一系列的过程,将站点的要素以等值线图的形式进行显示,使用方便,取得了不错的效果。

With the increase of atmospheric observation data,how to simply and conveniently use the data become a difficult problem.Therefore,designing graphics software is necessary.Combing with the actual situation in daily work of Lishui Weather Bureau,C ＋＋ Builder6.0 was used to design software,directly inputting elements data or inquiring automating station data,through establishment of regular network model,meshing of discrete point data,contour tracing,smoothing and dynamic marking,elements were displayed by contour map,which is convenient and achieves a good effect.
