基于Surfer的地学数据快速可视化研究及应用

Rapid visualization of geoscience data based on Surfer and its applications

为了研究不同插值方法进行数据插值的结果差异和评价特征。运用可视化的开发工具VB 6.0中集成的Surfer软件,可以使用12种插值方法进行数据插值,根据客户的不同需要实现了等高线、三维曲面等地学数据的快速显示,并可以对插值的结果进行定量评价。以湖南省平均温度为例,通过多种方法的比较结果表明:不同插值方法得出的结果有所差异,具体情况要具体分析;而且可从得到的叠加图上能够对数据的空间分布规律和某种走势进行预测和总结。

In order to analyze the performance of different algorithms for data interpolation,an evaluation system is setup.Using the visual development tools-Surfer software that integrated in VB 6.0,12 kinds of interpolation methods can be used to implement data interpolation.Geosciences data,such as contour,three-dimensional,etc,can be displayed rapidly for different users;moreover,quantitative assessment of the results of interpolation can be achieved.Taken the average temperature of HuNan providence as an example,experiment results shows that the performance of interpolation algorithms differ with specific conditions.Meanwhile,spatial distribution and tendency of the data can be predicted and summarized from the obtained overlay chart.
