arcgis中的extract value to points Extract Values to Points又叫“值提取至点”,是地理信息数据处理中的一种常用方法。该方法基于一组点要素,提取点对应的栅格像元值,并将这些值记录到输出点要素类的属性表中。 在Extract Values to Points的语法中,in_point_features为输入矢量点数据,in_raster为待提取的栅格...
得出最低点，并将最低点通过conversion to point 工具转成矢量点，打算使用extract value to point ...
现在有一个DEM和一个shape点文件,名称分别为“DEM”和“POINT”。将两者叠加后每个点会落在栅格数据的某个像元中,本文介绍如何将每个点所在的栅格像元值赋予其上的点。 将两个文件加载到ArcGIS的TOC窗口中,打开Toolbox,依此找到Spatial Analyst Tools—>Extraction—>Extract Value to Points,如图1所示。 双击打开Ex...
