必应词典为您提供Extract-Values-To-Points的释义,网络释义: 提取值到点;点值获取;
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为待提取的栅格数据,out_point_features为输出矢量点数...
To extract values from multiple rasters or a multiband raster dataset, use the Extract Multi Values To Points tool. The interpolation option determines how the values will be obtained from the raster. The default option is to extract the exact cell value at the input locations. To extract inte...

1、在ArcGIS中进行“值提取至点”操作时，不要将同一.tif文件加载进ENVI中，因为可能会占用，而处理...
图1 Extract Value to Points在ArcToolbox中的位置 图2 Extract Value by Points对话框设置 设置完成后点击OK进行计算,待计算结束后,提取出栅格像元值的点文件会自动添加到当前的TOC窗口中。打开属性表可以看到多了一列名为“RASTERVALU”的字段,该字段中存储的就是每个矢量点对应的栅格数据的像元值,在这里即为高程...
extract values to points Extracting values to points refers to the process of converting data stored in a raster format, such as a satellite image or a digital elevation model, into a point feature dataset. This involves extracting the values of the pixels or cells in the raster and ...
1、尽量选择默认输出路径，待数据出来后再重新导成自己所想命名的名字；2、命名的数据名称尽量用半角字符...
使用前台运行试试，后台执行工具经常不稳定。方法：地理处理菜单->地理处理选项->取消后台执行（使用前台执行）。
