【摘要】 介绍了利用ArcGIS与Surfer进行等深线提取的基本流程,从插值方法、地图整饰、白化处理与数据格式转换等几个关键技术出发,对ArcGIS与Surfer两个软件的等深线提取功能进行了对比分析,并比较了黄河口区域水深等值线的提取结果。结果表明:在相同插值方法与参数设置的情况下,ArcGIS与Surfer提取的等深线在空间分布上基本一致;两种软件各具特点,在实际应用中,应该根据具体情况选择使用软件。更多还原

【Abstract】 This paper introduces the general process of extracting isobath using ArcGIS and Surfer.From the key technologies of interpolate method,map decoration,blank operation and data transformation,it relatively analyzes the isobath extracting functions of ArcGIS and Surfer,and compares the isobath results of the Yellow River estuary.The results show that a) by using the same interpolation method and parameters,the isobath space distributions of ArcGIS and Surfer are almost the same;and b) because both softwares have their own characteristics,the specific circumstances should be considered to choose the right software in actual applications.更多还原
