摘要
ESRI公司提供的ArcGIS Desktop广泛应用于雷电分布数据的处理与显示上,但是由于不能进行批处理,严重影响工作效率。根据国家级雷电数据库中的雷电分布数据,进行密度分析处理后得到样本空间内的格点处密度值。为得到连续的栅格数据,以IDW插值算法为基础,基于ArcGIS Engine组件进行二次开发,实现一种雷电分布数据的批量密度处理方法。对样本空间内的雷电分布数据进行检索,重新组织数据格式并进行批量插值操作,将结果以图形化的形式显示。在8月中旬"海葵"台风影响下的华东地区雷电密度分布处理的应用结果表明,利用该方法可得到大批量可信度较高的雷电密度分布数据。
ESRI＇s ArcGIS Desktop is widely used in the lightning distributed data processing and display, but due to its inability to carry out batch operation, seriously affecting work efficiency. According to the tlightning distribution data in the database of the National lightning, can obtain the density value of the grid points in the sample space with processed densityanalysis. In order to obtain a continuous raster data, based on IDW interpolation algorithm and ArcGIS secondary development Engine components, achieve a method for Lightning distribution data＇s bulk density processing. To retrieve the lightning distribution data within sample space, reorganize the data formats and bulk in- terpolation operation, and display results in graphical form. In mid-August, under the influence of the ＂anemone＂ Typhoon, the lightning density distribution processing application results of east China show that the method can be used to get large quantities of high credible lightning density distribution data.
