摘要
通过实例介绍了用UN-SCAN-IT软件数字化等高线的方法,根据实例获得的数字高层模型数据,利用修正高斯模式,计算出复杂地形高程点的浓度值,然后利用Surfer 8.0绘制污染物的等质量浓度分布图。最后,对以上两个软件的优缺点和应用前景进行了简要分析。
It was introduced a way of digitizing contour lines with UN-SCAN-IT by an example. According to the DEM dates gotten from the example, the concentration of the complex terrain was calculated with the correctional Gaussian model, and generated the concentration distribution map by Surfer 8.0. Finally,it was given a brief analysis of the vantages and deficiencies, and the application prospects of these software.
